Ibhlog yeCW kaDisemba ka-2021, "IiSensors ze-Ultrasonic zesiko loPhuculo lweNkqubo eDityanisiweyo kunye noLawulo," ichaza umsebenzi kwiYunivesithi yaseAugsburg (UNA, Augsburg, eJamani) ukuphuhlisa inethiwekhi ye-74 sensors ukuba iCosiMo Iprojekthi yokuvelisa i-demonstrator ye-EV yebhetri ye-cover (izinto ezidibeneyo kwi-smart transportation) . kwi-UNA kunye neNtloko ye-UNA's Artificial Intelligence (AI) Network Network e-Augsburg, ichaza ukuba kutheni i-sensor zibaluleke kakhulu: "Eyona nto iluncedo kakhulu esiyinikelayo kukubonwa kwento eyenzekayo ngaphakathi kwebhokisi emnyama ngexesha lokucubungula. Okwangoku, abaninzi abavelisi baneenkqubo ezilinganiselweyo zokuphumeza oku. Umzekelo, basebenzisa i-sensor ezilula kakhulu okanye ezikhethekileyo xa besebenzisa i-resin infusion ukwenza iindawo ezinkulu ze-aerospace. Ukuba inkqubo yokufakwa ayihambanga kakuhle, ngokusisiseko uneqhekeza elikhulu lesilahlwa. Kodwa ukuba unezisombululo zesisombululo sokuqonda ukuba yintoni engahambi kakuhle kwinkqubo yemveliso kwaye kutheni, ungayilungisa kwaye uyilungise, ulondoloze imali eninzi. ”
I-Thermocouples ngumzekelo "wenzwa elula okanye ekhethekileyo" esetyenzisiweyo amashumi eminyaka ukujonga ubushushu be-laminates edibeneyo ngexesha lokunyanga kwe-autoclave okanye i-oven. i-thermal bonders.Abenzi be-Resin basebenzisa iintlobo ezahlukeneyo ze-sensors kwilebhu ukujonga utshintsho kwi-resin viscosity ngokuhamba kwexesha kunye nokushisa ukuphuhlisa ukubunjwa konyango.Yintoni ephumayo, nangona kunjalo, inethiwekhi yenzwa enokubona kunye nokulawula inkqubo yokuvelisa kwi-situ esekelwe iiparamitha ezininzi (umzekelo, ubushushu kunye noxinzelelo) kunye nemeko yezinto (umz., viscosity, aggregation, crystallization).
Ngokomzekelo, i-sensor ye-ultrasonic iphuhliswe kwiprojekthi ye-CosiMo isebenzisa imigaqo efanayo yokuhlola i-ultrasonic, eye yaba yinto ephambili yovavanyo olungonakalisi (NDI) lwamacandelo adibeneyo agqityiweyo.Petros Karapapas, iNjineli eyiNjineli eMeggitt (Loughborough, UK), Uthe: "Injongo yethu kukunciphisa ixesha kunye nomsebenzi ofunekayo wokuhlolwa emva kokuveliswa kwezinto ezizayo njengoko sisiya kwimveliso yedijithali." I-Materials Centre (NCC, Bristol, UK) intsebenziswano ukubonisa ukubekwa esweni kwe-Solvay (Alpharetta, GA, USA) EP 2400 ring ngexesha le-RTM isebenzisa i-sensor ye-dielectric ye-linear ephuhliswe kwiYunivesithi yaseCranfield (eCranfield, e-UK) Ukuhamba kunye nokunyangwa kwe-oxyresin ukwenzela I-1.3 m ubude, 0.8 m ububanzi kunye ne-0.4 m ubunzulu obuhlanganisiweyo beqokobhe le-injini yokuthengisa ubushushu benqwelo-moya. “Njengoko besijonga indlela yokwenza iindibano ezinkulu ezinemveliso ephezulu, besingenako ukwenza lonke uhlolo lwasemva kokwenziwa komsebenzi kwaye kuvavanyo kuwo onke amacandelo, ”utshilo uKarapapas. ”Okwangoku, senza iiphaneli zovavanyo ecaleni kwezi nxalenye zeRTM emva koko senze uvavanyo ngoomatshini ukuze siqinisekise umjikelo wonyango. Kodwa ngale sensor, ayiyomfuneko. ”
I-Collo Probe igxininiswe kwisitya sokuxuba ipeyinti (isangqa esiluhlaza phezulu) ukubona xa ukuxuba kugqityiwe, ukonga ixesha kunye namandla.Ikhredithi yomfanekiso: ColloidTek Oy
“Injongo yethu asikokuba sesinye isixhobo selabhoratri, kodwa kukujolisa kwiinkqubo zemveliso,” utshilo uMatti Järveläinen, iCEO kunye nomseki weColloidTek Oy (eKolo, eTampere, eFinland). I-CW kaJanuwari ka-2022 ibhlog ethi "Fingerprint Liquids for Composites" iphonononga iCollo's. indibaniselwano yezinzwa ze-electromagnetic field (EMF), inkqubo yomqondiso kunye nohlalutyo lwedatha ukulinganisa "uphawu lweminwe" lwalo naluphi na ulwelo olufana ne-monomers, iiresin okanye izinto ezincamathelayo . Uyiqonde ngcono indlela esebenza ngayo ngokwenene inkqubo yakho kwaye usabele xa izinto zingahambi kakuhle,” utshilo uJärveläinen. “Izinzwa zethu ziguqula idatha yexesha lokwenyani ibe yimiyinge eqondakalayo nenokusetyenzwa, efana nerheological viscosity, evumela ukuphuculwa kwenkqubo. Umzekelo, unokunciphisa amaxesha okuxuba kuba unokubona ngokucacileyo xa ukuxuba kuphelile. Ke ngoko, kunye Ungonyusa imveliso, wonge amandla kwaye unciphise i-scrap xa kuthelekiswa nokulungiswa okuncinci.
Injongo #2: Ukwandisa ulwazi lwenkqubo kunye nokubonwayo. Kwiinkqubo ezifana nokuhlanganiswa, u-Järveläinen uthi, "Awuboni ulwazi oluninzi kwi-snapshot. Uthatha nje isampuli kwaye ungene kwi-lab kwaye ujonge ukuba bekunjani kwimizuzu okanye kwiiyure ezidlulileyo. Kufana nokuqhuba kuhola wendlela, iyure nganye Vula amehlo akho umzuzu uze uzame ukuqikelela ukuba iya phi na indlela.” USause uyavuma, ephawula ukuba inethiwekhi yenzwa ephuhliswe kwi-CosiMo "isinceda ukuba sifumane umfanekiso opheleleyo wenkqubo kunye nokuziphatha kwezinto eziphathekayo. Sinokubona imiphumo yendawo kwinkqubo, ekuphenduleni Ukwahluka kwinxalenye yobunzima okanye izinto ezidibeneyo ezifana ne-foam core. Into esizama ukuyenza kukubonelela ngolwazi malunga nokuba kwenzekani ngokwenene kubumba. Oku kusivumela ukuba sigqibe ngeenkcukacha ezahlukeneyo ezinje ngemilo ye-flow front, ukufika kwexesha ngalinye kunye neqondo lokudityaniswa kwindawo nganye yoluvo.
I-Collo isebenza kunye nabavelisi be-epoxy adhesives, iipeyinti kunye nobhiya ukudala iiprofayili zenkqubo kwibhetshi nganye eveliswayo.Ngoku wonke umenzi unokujonga ukuguqulwa kwenkqubo yabo kwaye usete iiparitha eziphuculweyo, kunye nezilumkiso zokungenelela xa iibhetshi ziphuma kwinkcazo.Oku kunceda. uzinzise kwaye uphucule umgangatho.
Ividiyo ye-flow front kwinxalenye ye-CosiMo (i-injection yokungena lichaphaza elimhlophe embindini) njengomsebenzi wexesha, ngokusekelwe kwidatha yokulinganisa evela kwinethiwekhi ye-sensor e-mold.Ikhredithi yomfanekiso: iprojekthi ye-CosiMo, i-DLR ZLP Augsburg, iYunivesithi yase-Augsburg Augsburg
"Ndifuna ukwazi ukuba kwenzeka ntoni ngexesha lokwenziwa kwenxalenye, ungayivuli ibhokisi kwaye ndibone ukuba kwenzeka ntoni emva koko," utshilo uMeggitt's Karapapas. ukuqinisekisa ukunyangwa kwe-resin. Ukusebenzisa zonke iintlobo ezintandathu ze-sensor ezichazwe ngezantsi (kungekhona uluhlu olupheleleyo, ukhetho oluncinci, ababoneleli, nabo), banokubeka iliso kunyango / i-polymerization kunye ne-resin flow.Ezinye izinzwa zinezakhono ezongezelelweyo, kunye neentlobo ze-sensor ezidibeneyo zinokwandisa amathuba okulandelela kunye nokubonwa. ngexesha lokubumba okudibeneyo.Oku kubonakaliswe ngexesha le-CosiMo, esebenzisa i-ultrasonic, i-dielectric kunye ne-piezoresistive in-mode sensors yeqondo lokushisa kunye nemilinganiselo yoxinzelelo nguKistler (Winterthur, Switzerland).
Injongo #3: Ukunciphisa ixesha lomjikelo.Izinzwa ze-Collo zinokulinganisa ukufana kwe-epoxy yamacandelo amabini ngokukhawuleza njengoko iinxalenye A kunye ne-B zixutywe kwaye zijovwe ngexesha le-RTM nakuyo yonke indawo ekubunjeni apho zibekwe khona ezo nzwa. i-resins zonyango olukhawulezayo lwezicelo ezifana ne-Urban Air Mobility (UAM), eya kubonelela ngemijikelo yonyango olukhawulezayo xa kuthelekiswa ne-epoxies enye yangoku efana ne-RTM6.
Abenzi boluvo be-Collo banokubeka iliso kwaye babone i-epoxy ichithwa, ifakwe kwaye iphiliswe, kwaye xa inkqubo nganye igqityiwe.Ukugqiba ukunyanga kunye nezinye iinkqubo ezisekelwe kwimeko yokwenyani yezinto ezicutshungulwayo (ngokuchasene nexesha lemveli kunye neeresiphi zokushisa) kubizwa ngokuba yi-state material management. (MSM) .Iinkampani ezifana ne-AvPro (eNorman, e-Oklahoma, eU.SA) zilandela i-MSM kangangamashumi eminyaka ukulandelela utshintsho kwinxalenye yezixhobo kunye neenkqubo njengoko zilandela iithagethi ezithile zobushushu beglasi (Tg), viscosity, polymerization kunye/okanye. crystallization .Ngokomzekelo, inethiwekhi yeenzwa kunye nohlalutyo lwedijithali kwi-CosiMo yayisetyenziselwa ukumisela ixesha elincinci elifunekayo ukutshisa i-RTM press and mold kwaye yafumanisa ukuba i-96% ye-polymerization ephezulu ifunyenwe kwimizuzu ye-4.5.
Abathengisi be-Dielectric sensor ezifana ne-Lambient Technologies (i-Cambridge, MA, i-USA), i-Netzsch (i-Selb, iJamani) kunye ne-Synthesites (i-Uccle, eBelgium) baye babonisa amandla abo okunciphisa amaxesha okujikeleza. ) kunye ne-Bombardier Belfast (ngoku i-Spirit AeroSystems (i-Belfast, e-Ireland)) ibika ukuba ngokusekelwe kwimilinganiselo yexesha langempela lokumelana ne-resin kunye nobushushu, ngokusebenzisa iyunithi yokufumana idatha ye-Optimold kunye ne-Optiview Software iguqulela kwi-viscosity eqikelelweyo kunye ne-Tg. "Abavelisi banokubona i-Tg. ngexesha lokwenyani, ukuze bakwazi ukwenza isigqibo sokuba bawuyeke nini umjikelo wokunyanga,” ucacisa watsho uNikos Pantelelis, uMlawuli weSynthesites. “Akuyomfuneko ukuba balinde ukuze bagqibezele umjikelo wecarryover omde kunokuba kuyimfuneko. Umzekelo, umjikelo wesiqhelo we-RTM6 lunyango olupheleleyo lweyure ezi-2 kwi-180°C. Sibonile ukuba oku kungenziwa mfutshane ukuya kwimizuzu engama-70 kwezinye iijiyometri. Oku kwaboniswa kwakhona kwiprojekthi ye-INNOTOOL 4.0 (jonga "Ukukhawulezisa i-RTM kunye ne-Heat Flux Sensors"), apho ukusetyenziswa kwenzwa yokushisa kunciphise umjikelezo wokunyanga i-RTM6 ukusuka kwi-120 imizuzu ukuya kwi-90 imizuzu.
Injongo #4: Ukulawulwa kwe-loop evaliweyo yeenkqubo eziguquguqukayo.Kwiprojekthi ye-CosiMo, eyona njongo iphambili kukwenza ngokuzenzekelayo ulawulo oluvaliweyo ngexesha lokuveliswa kweengxenye ezidibeneyo.Le yinjongo ye-ZAero kunye ne-iComposite 4.0 yeeprojekthi ezichazwe nguCW I-2020 (i-30-50% yokunciphisa iindleko) .Qaphela ukuba ezi zibandakanya iinkqubo ezahlukeneyo - ukufakwa ngokuzenzekelayo kwe-tape ye-prepreg (ZAero) kunye ne-fiber spray preforming xa kuthelekiswa noxinzelelo oluphezulu lwe-T-RTM kwi-CosiMo ye-RTM kunye ne-epoxy yokuphilisa ngokukhawuleza (iComposite 4.0). kwezi projekthi zisebenzisa abenzi boluvo abaneemodeli zedijithali kunye ne-algorithms ukulinganisa inkqubo kunye nokuqikelela isiphumo senxalenye egqityiweyo.
Ukulawulwa kwenkqubo kunokucingwa njengoluhlu lwamanyathelo, i-Sause ichaze.Isinyathelo sokuqala kukudibanisa i-sensor kunye nezixhobo zokusebenza, wathi, "ukubona ngeso lengqondo into eyenzekayo kwibhokisi elimnyama kunye neeparitha zokusebenzisa. Amanye amanyathelo ambalwa, mhlawumbi isiqingatha solawulo oluvaliweyo, luyakwazi ukucofa iqhosha lokumisa ukuze lingenelele, Lungelelanisa inkqubo kwaye uthintele iindawo ezaliwe. Njengenyathelo lokugqibela, unokuphuhlisa iwele ledijithali, elinokuthi lizisebenzele, kodwa likwafuna utyalo-mali kwiindlela zokufunda koomatshini. " Kwi-CosiMo, olu tyalo-mali luvumela abenzi boluvo ukuba bondle idatha kwiwele ledijithali, uhlalutyo lwe-Edge (ubalo olwenziwe kumda womgca wemveliso ngokuchasene nokubalwa okuvela kwindawo yokugcina idatha) isetyenziselwa ukuqikelela ukuhamba phambili kwamandla, umthamo we-fiber umthamo kwi-textile preform. kunye neendawo ezomileyo ezinokuthi zibe kho.” Ngokunqwenelekayo, unokuseta useto oluvumela ulawulo lwe-loop evaliweyo kunye nokulungisa inkqubo,” utshilo u-Sause. Unokusebenzisa le nkcazelo ukwandisa umbandela wakho.”
Ngokwenza njalo, iinkampani zisebenzisa i-sensor ukwenza ngokuzenzekelayo iinkqubo.Ngokomzekelo, i-Synthesites isebenza kunye nabathengi bayo ukudibanisa i-sensor kunye nezixhobo zokuvala i-resin inlet xa i-infusion iphelile, okanye uvule umshicileli wokushisa xa unyango olujoliswe kuyo lufezekiswa.
UJärveläinen uphawula ukuba ukufumanisa ukuba yeyiphi inzwa elungele imeko nganye yokusetyenziswa, "kuya kufuneka uqonde ukuba loluphi utshintsho kwizinto kunye nenkqubo ofuna ukuyijonga, emva koko kufuneka ube nesihlalutyi." I-analyzer ifumana idatha eqokelelwe ngumhloli-mibuzo okanye iyunithi yokufumana idatha. idatha ekrwada kwaye uyiguqule ibe lulwazi olunokusetyenziswa ngumenzi. "Okunene ubona iinkampani ezininzi ezidibanisa izinzwa, kodwa ke azenzi nto ngedatha," utshilo uSause. Yintoni efunekayo, wachaza, "yinkqubo yokufunyanwa kwedatha, kunye noyilo lokugcinwa kwedatha ukuze ukwazi ukucubungula idatha. "
“Abasebenzisi bokugqibela abafuni nje ukubona idatha ekrwada,” utsho uJärveläinen.” Bafuna ukwazi, ‘Ingaba inkqubo yenziwe yalungiswa?’” Linokuthatyathwa nini inyathelo elilandelayo?” Ukwenza oku, kufuneka udibanise izinzwa ezininzi. kuhlahlelo, kwaye emva koko usebenzise ukufundwa koomatshini ukukhawulezisa inkqubo. ” Olu hlalutyo lwamaphethelo kunye nendlela yokufunda yomatshini esetyenziswa yiqela leCollo kunye neCosiMo inokufezekiswa ngeemephu ze-viscosity, iimodeli zamanani ze-resin flow flow front, kwaye Ukukwazi ekugqibeleni ukulawula iiparitha zenkqubo kunye noomatshini babonwa.
I-Optimold yi-analyzer ephuhliswe yi-Synthesites ye-dielectric sensors.Ilawulwa yi-software ye-Synthesites 'Optiview, iyunithi ye-Optimold isebenzisa imilinganiselo yokushisa kunye ne-resin yokumelana ne-resin ukubala nokubonisa iigrafu zexesha langempela ukujonga imeko ye-resin kubandakanya umxube wokuxuba, ukuguga kweekhemikhali, i-viscosity, i-Tg. kunye neqondo lokunyanga.Inokuthi isetyenziswe kwiinkqubo ze-prepreg kunye ne-liquid forming process.Iyunithi eyahlukileyo i-Optiflow isetyenziselwa ukujonga ukuhamba. inzwa yobushushu kunye neesampuli ze-resin / prepreg kule yunithi yokuhlalutya. "Sisebenzisa le ndlela ye-state-of-art ye-infusion kunye ne-adhesive curing ye-wind turbine blade production," watsho u-Nikos Pantelelis, uMlawuli we-Synthesites.
Iinkqubo zolawulo lwenkqubo ye-Synthesites zidibanisa abenzi boluvo, i-Optiflow kunye/okanye iiyunithi zokufunyanwa kwedatha ye-Optimold, kunye nesoftware ye-OptiView kunye/okanye ye-Online Resin Status (ORS).Ikhredithi yomfanekiso: Synthesites, ihlelwe yi-CW
Ngoko ke, abaninzi abanikezeli be-sensor baye baphuhlisa abahlalutyi babo, abanye basebenzisa ukufundwa komatshini kwaye abanye abakwenzi.Kodwa abavelisi abadibeneyo banokuphinda baphuhlise iinkqubo zabo zesiko okanye bathenge izixhobo ezingaphandle kwe-shelf kwaye baziguqule ukuhlangabezana neemfuno ezithile.Nangona kunjalo, amandla okuhlaziya inye kuphela into ekufuneka iqwalaselwe.Zininzi ezinye.
Uqhagamshelwano nalo luyingqwalasela ebalulekileyo xa ukhetha ukuba yeyiphi inzwa yokusetyenziswa.Inzwa inokufuna ukuba idibane nezinto eziphathekayo, i-interrogator, okanye zombini.Ngokomzekelo, ukufudumala kobushushu kunye neenzwa ze-ultrasonic zingafakwa kwi-RTM mold 1-20mm ukusuka. umphezulu - esweni echanekileyo ayifuni ukudibana nezinto ekubumbeni.Iinzwa ze-Ultrasonic nazo ziyakwazi ukugocagoca iindawo kubunzulu obuhlukeneyo ngokuxhomekeke kwi-frequency esetyenzisiweyo.I-Collo sensors ze-electromagnetic nazo zingafunda ubunzulu bolwelo okanye iinxalenye - 2-10 cm, ngokuxhomekeke ngokuphindaphindiweyo ukugocagocwa - kunye nezikhongozeli ezingezizo ezentsimbi okanye izixhobo ezidibana nentlaka.
Nangona kunjalo, i-microwires magnetic (bona "Ukujongwa okungadibaniyo nobushushu kunye noxinzelelo ngaphakathi kwee-composites") okwangoku kuphela kwezivamvo ezikwazi ukubuza ii-composites kumgama we-10 cm. ifakwe kwizinto ezidibeneyo.Inzwa ye-microwire ye-AvPro's ThermoPulse, efakwe kwi-adhesive bond layer, iye yancinwa nge-25mm ye-carbon fiber laminate ukulinganisa ubushushu ngexesha lenkqubo yokudibanisa. Azichaphazeli i-composite okanye i-bondline performance.Kwi-diameters ezinkulu kancinane ze-100-200 microns, i-fiber optic sensors nazo zinokufakelwa ngaphandle kokuthotywa kwezakhiwo zesakhiwo.Nangona kunjalo, ngenxa yokuba zisebenzisa ukukhanya ukulinganisa, i-fiber optic sensors kufuneka ibe noqhagamshelwano olucingo Ngokukwanjalo, ekubeni izinzwa ze-dielectric zisebenzisa i-voltage ukulinganisa iipropathi ze-resin, kufuneka ziqhagamshelwe kwi-interrogator, kwaye ininzi kufuneka idibane ne-resin abayijongileyo.
I-sensor ye-Collo Probe (phezulu) inokuntywiliselwa kumanzi, ngelixa i-Collo Plate (ezantsi) ifakwe eludongeni lwesitya / isitya sokuxuba okanye inkqubo yombhobho / umgca wokutya.Ikhredithi yomfanekiso: ColloidTek Oy
Umgangatho wokushisa we-sensor yinto enye ephambili yokuqwalaselwa.Ngokomzekelo, ininzi ye-shalf-shelf ultrasonic sensors isebenza ngokuqhelekileyo kumaqondo okushisa ukuya kwi-150 ° C, kodwa iinxalenye kwi-CosiMo kufuneka zenziwe kumaqondo okushisa angaphezu kwe-200 ° C. Ngoko ke, i-UNA Kuye kwafuneka ukuba kuyilwe i-ultrasonic sensor ngobu buchule.Izinzwa zedielectric ezilahlwayo zeLambient zinokusetyenziswa kwindawo ethile ukuya kuthi ga kwi-350 ° C, kwaye izinzwa zayo eziphinda zisetyenziswe ekungundeni zingasetyenziswa ukuya kuthi ga kwi-250 ° C.RVmagnetics (Kosice, Slovakia) inzwa yayo ye-microwire yezinto ezidibeneyo ezinokumelana nokunyanga kwi-500 ° C. Ngelixa iteknoloji ye-Collo sensor ngokwayo ayinayo umda weqondo lokushisa, i-glass shield ye-Collo Plate kunye nendlu entsha ye-polyetheretherketone (PEEK) ye-Collo Probe zombini zivavanywa. ngomsebenzi oqhubekayo kwi-150 ° C, ngokutsho kweJärveläinen. Ngelo xesha, i-PhotonFirst (Alkmaar, e-Netherlands) yasebenzisa i-polyimide yokugqoka ukubonelela ukushisa okusebenzayo kwe-350 ° C kwi-fiber optic sensor yayo yeprojekthi ye-SuCoHS, ukwenzela ukugcinwa kunye neendleko- indibaniselwano esebenzayo yobushushu obuphezulu.
Enye into ekufuneka iqwalaselwe, ngokukodwa ukufakela, ingaba i-sensor imilinganiselo kwindawo enye okanye i-sensor ye-linear eneendawo ezininzi zokuva.Ngokomzekelo, i-Com & Sens (Eke, eBelgium) i-fiber optic sensors ingaba yi-100 yeemitha ubude kwaye ibonise phezulu. ukuya kwi-40 i-fiber Bragg grating (FBG) iindawo zokuva kunye nesithuba esincinci se-1 cm. Ezi zinzwa zisetyenziselwe ukubeka iliso kwi-structural health (SHM) ye-66-meter-long-composite bridges kunye ne-resin flow monitoring ngexesha lokugalelwa kwe-bridge enkulu. abenzi boluvo bomntu ngamnye kwiprojekthi enjalo baya kufuna inani elikhulu lee-sensor kunye nexesha elininzi lokufakela.I-NCC kunye neYunivesithi yaseCranfield babanga iinzuzo ezifanayo kwii-dielectric sensors zabo zomgca.Xa kuthelekiswa ne-single-point dielectric sensors ezibonelelwa yiLambient, Netzsch kunye ne-Synthesites, " Ngenzwa yethu yomgca, sinokubeka iliso ukuhamba kwe-resin ngokuqhubekayo kubude, nto leyo inciphisa kakhulu inani leenzwa ezifunekayo kwinxalenye okanye isixhobo.
I-AFP NLR ye-Fiber Optic Sensors Iyunithi ekhethekileyo idibaniswe kwi-channel ye-8 ye-Coriolis AFP intloko yokubeka i-fiber optic sensor arrays ezine kwiqondo lokushisa eliphezulu, i-carbon fiber iqiniswe iphaneli yovavanyo oludibeneyo.Ikhredithi yomfanekiso: Iprojekthi ye-SuCoHS, i-NLR
I-sensors ze-linear nazo zinceda ukufakwa kwe-automate.Kwiprojekthi ye-SuCoHS, i-Royal NLR (i-Dutch Aerospace Centre, i-Marknesse) iphuhlise iyunithi ekhethekileyo edibeneyo kwi-channel ye-8 ye-Automated Fiber Placement (AFP) intloko ye-Coriolis Composites (iQueven, eFransi) ukuze ifake ii-arrays ezine ( imigca yefiber optic eyahlukileyo), nganye inezinzwa ze-5 ukuya kwezi-6 ze-FBG (i-PhotonFirst inika i-23 iyonke yoluvo), kwiipaneli zovavanyo lwe-carbon fiber.RVmagnetics ibeke i-microwire sensors yayo kwi-pultruded GFRP rebar.”Iingcingo aziqhubeki [1-4 cm. zinde kwii-microwires ezininzi ezihlanganisiweyo], kodwa zibekwe ngokuqhubekayo xa kuveliswa i-rebar,” utshilo uRatislav Varga, umseki weRVmagnetics. “Unocingo oluncinci olune-1km microwire. iikhoyili zefilament kwaye zondle kwindawo yokuvelisa i-rebar ngaphandle kokutshintsha indlela eyenziwe ngayo. Ngeli xesha, iCom & Sens isebenza kwitekhnoloji ezenzekelayo yokufaka i-fiber-optic sensors ngexesha lenkqubo yokuguqula i-filament kwiinqanawa zoxinzelelo.
Ngenxa yokukwazi ukuqhuba umbane, i-carbon fiber inokubangela iingxaki kwi-dielectric sensors.I-dielectric sensors zisebenzisa i-electrode ezimbini ezibekwe kufutshane enye kwenye. Kule meko, sebenzisa isihluzi. I-sensor ye-dielectric ye-linear ephuhliswe yiYunivesithi yaseCranfield kunye ne-NCC isebenzisa indlela eyahlukileyo, kubandakanywa izibini ezimbini eziphothiweyo zobhedu. ngepolymer ekhuselayo engachaphazeli intsimi yombane, kodwa ithintela i-carbon fiber ukuba ingabikho.
Ngokuqinisekileyo, ixabiso likwangumcimbi.I-Com & Sens ithi i-avareji yeendleko kwi-FBG sensing point yi-50-125 euro, enokuthi yehle ukuya kuma-euro angama-25-35 ukuba isetyenziswe kwiibhetshi (umzekelo, kwiinqanawa ze-100,000 zoxinzelelo). kuphela iqhezu lemveliso yangoku kunye nomthamo oqikelelweyo wemikhumbi yoxinzelelo oludibeneyo, jonga i-CW's 2021 inqaku kwi-hydrogen.) U-Meggitt's Karapapas uthi ufumene izibonelelo zemigca ye-fiber optic kunye ne-FBG sensors ephakathi kwe-£ 250 / inzwa (≈300 € / inzwa), umntu ogocagoca ngemibuzo uxabisa malunga ne-£10,000 (e-€12,000).” Isivamvo sombane esisivavanyileyo sasifana nocingo olugqunyiweyo onokuluthenga eshelufini,” wongeze watsho u-Alex Skordos. umphandi ophezulu) kwiComposites Process Science kwiYunivesithi yaseCranfield, "yi-impedance analyzer, echaneke kakhulu kwaye ixabisa i-£ 30,000 ubuncinane [≈ €36,000], Kodwa i-NCC isebenzisa umntu obuza imibuzo olula kakhulu oluquka ngaphandle kwe-shelf. iimodyuli ezivela kwinkampani yorhwebo Advise Deta [Bedford, UK].” I-Synthesites icaphula i-€ 1,190 ye-in-mold sensors kunye ne-€20 yokusetyenziswa okukodwa / i-sensor yecandelo Kwi-EUR, i-Optiflow icatshulwa kwi-EUR 3,900 kunye ne-Optimold ye-EUR 7,200, kunye nezaphulelo ezikhulayo kwiiyunithi ezininzi zokuhlalutya.La maxabiso aquka i-software ye-Optiview inkxaso eyimfuneko, uPantelelis uthe, wongeza ukuba abavelisi be-wind blade bagcina iiyure ze-1.5 kumjikelo ngamnye, zongeza ii-blades ngomgca ngamnye ngenyanga, kunye nokunciphisa ukusetyenziswa kwamandla ngama-20 ekhulwini, kunye nembuyekezo kutyalo-mali lweenyanga ezine kuphela.
Iinkampani ezisebenzisa i-sensor ziya kufumana inzuzo njengoko i-composites i-4.0 yokuvelisa i-digital evolves.Ngokomzekelo, uthi uGrégoire Beauduin, uMlawuli woPhuhliso lwezoShishino kwi-Com & Sens, "Njengoko abavelisi beenqanawa zoxinzelelo bezama ukunciphisa ubunzima, ukusetyenziswa kwezinto eziphathekayo kunye neendleko, banokusebenzisa iinzwa zethu ukulungelelanisa. Uyilo lwazo kunye nokubeka iliso kwimveliso njengoko befikelela kumanqanaba afunekayo ngo-2030. Izinzwa ezifanayo ezisetyenziselwa ukuvavanya amanqanaba oxinzelelo ngaphakathi kweeleya ngexesha lokujika kwe-filament kunye nokunyanga nako kunokubeka iliso kwingqibelelo yetanki ngexesha lamawaka emijikelo yokugalela i-refueling, ukuqikelela ukugcinwa okufunekayo kunye nokuqinisekiswa kwakhona ekupheleni koyilo. ubomi. Singakwazi Idijithi yedatha yamawele edijithali ibonelelwe kuyo yonke inqanawa yoxinzelelo edibeneyo eveliswayo, kwaye isisombululo sikwaphuhliselwa iisathelayithi. "
Ukuvumela amawele edijithali kunye neentambo I-Com & Sens isebenza kunye nomvelisi we-composites ukusebenzisa i-fiber optic sensors yayo ukuze ikwazi ukuhamba kwedatha yedijithali ngokuyila, ukuveliswa kunye nenkonzo (ekunene) ukuxhasa amakhadi e-ID yedijithali axhasa iwele ledijithali lenxalenye nganye (ngasekhohlo) eyenziwe. Ikhredithi yomfanekiso: I-Com & Sens kunye ne-Figure 1, "Ubunjineli kunye neeNjineli zeDijithali" nguV. Singh, K. Wilcox.
Ngaloo ndlela, idatha ye-sensor isekela i-digital twin, kunye nentambo yedijithali edibanisa ukuyila, ukuveliswa, ukusebenza kwenkonzo kunye nokuphelelwa yisikhathi.Xa ihlalutywa ngokusebenzisa i-intelligence yokufakelwa kunye nokufunda ngomatshini, le datha ibuyisela kuyilo kunye nokucubungula, ukuphucula ukusebenza kunye nokuzinza. iphinde yatshintsha indlela amakhonkco onikezelo asebenza ngayo kunye.Ngokomzekelo, umenzi wokuncamathelisa uKiilto (iTampere, eFinland) usebenzisa iCollo sensors ukunceda abathengi bayo balawule umlinganiselo wamacandelo A, B, njl. ngoku inokuhlengahlengisa ukwakheka kwezinto ezincamathelayo kubathengi ngabanye, utshilo uJärveläinen, "kodwa ikwavumela uKiilto ukuba aqonde ukuba iiresin zidibana njani kwiinkqubo zabathengi, kunye nendlela abathengi abanxibelelana ngayo neemveliso zabo, etshintsha indlela okwenziwa ngayo unikezelo. Amatyathanga angasebenzisana.”
I-OPTO-Light isebenzisa i-Kistler, i-Netzsch kunye ne-Synthesites sensors ukujonga ukunyanga kwiindawo ze-epoxy ze-CFRP ze-thermoplastic. Ikhredithi yomfanekiso: AZL
IiSensors zikwaxhasa izinto ezintsha ezintsha kunye nokudibanisa inkqubo.Ichazwe kwi-CW's 2019 inqaku kwiprojekthi ye-OPTO-Light (bona "I-Thermoplastic Overmolding Thermosets, i-2-Minute Cycle, ibhetri enye"), i-AZL Aachen (Aachen, eJamani) isebenzisa amanyathelo amabini. inkqubo yokucinezela ngokuthe tye enye ukuya (UD) carbon fiber/epoxy prepreg, emva koko igqitywe nge-30% ifayibha yeglasi emfutshane eqiniswe nge-PA6.Isitshixo kukunyanga kuphela i-prepreg ukuze i-reactivity eseleyo kwi-epoxy ikwazi ukubopha kwi-thermoplastic. I-AZL isebenzisa i-Optimold kunye ne-Netzsch DEA288 Epsilon analyzers ezine-Synthesites kunye ne-Netzsch dielectric sensors kunye ne-Kistler in-mold sensors kunye ne-software ye-DataFlow yokuphucula ukubumba inaliti. baqonde imeko yokunyanga ukuze bazuze unxibelelwano olululo kwi-thermoplastic overmolding,” ucacisa ngelitshoyo injineli yophando ye-AZL uRichard Schares. "Kwixesha elizayo, inkqubo inokuguquguquka kwaye ikrelekrele, ukujikeleza kwenkqubo kubangelwa ziimpawu zoluvo."
Nangona kunjalo, kukho ingxaki esisiseko, utsho uJärveläinen, “kwaye oko kukungaqondi kwabathengi ngendlela yokudibanisa ezi zivamvo zahlukeneyo kwiinkqubo zabo. Uninzi lweenkampani azinazo iingcali zoluvo. ” Okwangoku, indlela eya phambili ifuna abavelisi beenzwa kunye nabathengi Utshintshiselwano ngolwazi emva naphambili.Imibutho efana ne-AZL, i-DLR (i-Augsburg, eJamani) kunye ne-NCC iphuhlisa ubuchule beenzwa ezininzi.USause uthe kukho amaqela ngaphakathi kwe-UNA, kunye ne-spin-off. Iinkampani ezibonelela ngokudityaniswa kwenzwa kunye neenkonzo zamawele edijithali. Wongeze ukuba inethiwekhi yemveliso ye-Augsburg AI iqeshe indawo ye-7,000-square-meter kule njongo, "ukwandisa iplani yophuhliso yeCosiMo kwindawo ebanzi kakhulu, kubandakanywa iiseli ezizenzekelayo ezidibeneyo, apho amaqabane amashishini. Ungabeka oomatshini, uqhube iiprojekthi kwaye ufunde ukudibanisa izisombululo ezintsha ze-AI. ”
UCarapappas uthe i-Meggitt's dielectric sensor demonstration kwi-NCC yayilinyathelo lokuqala kuloo nto. imfuno kwaye zeziphi izixhobo zokuodola. I-Digital automation iyaphuhla.
