Imodyuli yeCamshaft: ipulasitiki esikhundleni sensimbi
Okuqukethwe
Umkhiqizo omusha uthembisa izinzuzo ngokwesisindo, izindleko kanye nemvelo
Ngokubambisana noMahle noDaimler, abacwaningi eFraunhofer Institute benze into entsha yokwakhiwa kwecamshaft. Ngokusho kochwepheshe, lokhu kuzoletha izinzuzo eziningi.
Ngubani othe izinsuku zenjini yomlilo yangaphakathi zibaliwe? Uma ugcina ukuthi zingaki izinto ezintsha eziqhubekayo ezenzelwe uhlobo lwakudala lokunyakaza, uzothola kalula ukuthi lo mqondo ongaguquguquki wehaba, uma ungafakwanga kahle. Amaqembu ocwaningo ahlala ethula izixazululo ezintsha ezenza uphethiloli, udizili nezinjini zegesi zibe namandla kakhulu, zonge uphethiloli, futhi kaningi ngasikhathi sinye.
Kuqiniswe nge-resin yokwenziwa esikhundleni se-aluminium.
Lokhu kwenziwa ososayensi eFraunhofer Institute for Chemical Technology (ICT). Ngokubambisana nochwepheshe bakwaDaimler, Mahle nabanye abahlinzeki bezinto zezimoto, basungule uhlobo olusha lwemodyuli ye-camshaft eyenziwe ngepulasitiki kunama-alloys alula. Imodyuli iyingxenye ebalulekile yesitimela sokushayela, ngakho-ke ukuzinza kuyisidingo esibaluleke kakhulu kubaklami. Kodwa-ke, iFraunhofer isebenzisa amandla amakhulu, i-fiber-reinforced thermosetting polymer (izinhlaka zokwenziwa) esikhundleni se-aluminium yemodyuli esebenza njengezindlu ze-camshaft.
Ababhali bentuthuko bathi lokhu kuzoletha izinzuzo eziningi ngasikhathi sinye. Ngakolunye uhlangothi, ngokwesisindo: "Imodyuli ye-camshaft isekhanda lesilinda, okungukuthi, imvamisa iphezulu kwendlela yokushayela," kuchaza uThomas Sorg, usosayensi eFraunhofer Institute. Lapha, ukonga isisindo kuyasiza kakhulu njengoba kwehlisa amandla adonsela phansi emoto. " Kepha akukuhle nje kuphela ngokuguquguquka komgwaqo. Ukwehla kwesisindo ekugcineni kungenye yezindlela eziphumelela kakhulu zokunciphisa ukukhishwa kwe-CO2 ezimotweni.
Izindleko nezinzuzo zesimo sezulu
Yize ingxenye yalesi sikhungo ilula ukwedlula imodyuli ye-aluminium camshaft, abasunguli bayo bathi imelana kakhulu namazinga okushisa aphezulu kanye nengcindezi yemishini neyamakhemikhali, njengaleyo edalwa uwoyela wezimoto zokwenziwa nama-coolants. Ngokusobala, intuthuko entsha nayo inezinzuzo. Njengoba oplastiki beziphatha njengabavikeli bemisindo, "indlela ezwakala ngayo imodyuli ye-camshaft ingenziwa kahle kakhulu," kuchaza uSorg.
Kodwa-ke, inzuzo enkulu kakhulu kungaba izindleko eziphansi. Ngemuva kokuphonsa, izingxenye ze-aluminium kumele zenze ukuqedelwa okubizayo futhi zibe nempilo elinganiselwe. Ngokuqhathanisa, izindleko zokucutshungulwa okungeziwe kwezinto ezisetshenziselwa i-fiber-reinforced thermosetting ziphansi kakhulu. Umklamo wazo we-monolithic uvumela ingxenye ukuthi icutshungulwe ngaphambili efektri, lapho ingafakwa khona enjinini ngokunyakaza kwesandla okumbalwa nje. Ngaphezu kwalokho, i-Fraunhofer ICT ithembisa ukuqina okukhulu okukhulu ekuthuthukisweni kwayo okusha.
Ekugcineni, kuzoba khona nezinzuzo zesimo sezulu. Njengoba ukukhiqizwa kwe-aluminium kunamandla amakhulu, i-carbon footprint yemodyuli ye-camshaft yeDurometer fiber kufanele ibe phansi kakhulu.
isiphetho
Okwamanje, imojula ye-camshaft ye-Institute of ICT. U-Fraunhofer usesesiteji semodeli esebenzayo yokubonisa. Ebhentshini lokuhlola injini, ingxenye ihlolwe amahora angu-600. "Sijabule kakhulu ngesibonelo esisebenzayo kanye nemiphumela yokuhlolwa," kusho uCatherine Schindele, umphathi wephrojekthi kwaMahle. Kodwa-ke, kuze kube manje abalingani abazange baxoxe ngesihloko sezimo lapho kungenzeka khona ukuhlela ukusetshenziswa kwe-serial yentuthuko.
