Ngokukhula kokukhiqizwa nokudayiswa kwezimoto, ukusetshenziswa kwamandla kanye nokukhipha ukungcola okukhiqizwa ngesikhathi sokukhiqizwa nokusetshenziswa kwezimoto kuyanda.Ngesikhathi esifanayo, ukungcoliswa kwemvelo nakho kuya ngokuya kugqama.Ngakho-ke, ukuze kuthuthukiswe intuthuko esimeme yemboni yezimoto, ngaphansi kwesisekelo sokuqinisekisa ukuqina, amandla, nokusebenza kokuphepha kwemoto, ngokushintsha impahla yesakhiwo semoto nezingxenye, isisindo semoto siyabonakala, okubalulekile ekwenzeni ngcono ukusebenza kahle kukaphethiloli wemoto kanye nokunciphisa izinto ezingcolisayo.Ukukhishwa kwekhabhoni kunomphumela wokuphromotha omkhulu kakhulu.Izimoto ezilula azikwazi nje ukugcina amandla futhi zinciphise ukukhishwa, kodwa futhi zithuthukise ukuzinza kanye namandla emoto ngesikhathi sokushayela.Lo mbhalo ikakhulukazi uchaza ingxubevange ye-magnesium ne-aluminium alloy, okumanje okuyizinto ezisetshenziswa kakhulu zezimoto ezingasindi, futhi ihlaziya izici nezinzuzo zazo, kanye nentuthuko yesikhathi esizayo ye-automotive lightweight.
Uma sibheka indlela yamanje yentuthuko, ukuze kuvikelwe indawo ezungezile futhi konge amandla nezinsiza, ucwaningo lwezimoto lwesikhathi esizayo nokuthuthukiswa kuzonaka kakhulu ukwakheka kwezimoto ezingasindi.Ukusetshenziswa kwezinto ezingasindi ezifana nensimbi enamandla amakhulu, ingxubevange ye-aluminium, ingxubevange ye-magnesium, nezinto ezihlanganisiwe ekukhiqizeni izimoto kungafinyelela ngempumelelo imoto engasindi.Ngaphezu kwalokho, izinqubo ezithuthukisiwe zokukhiqiza ezifana nokwakhiwa okushisayo, i-laser tailored welding, i-hydraulic forming, njll.Izimoto ezilula.Ingxubevange ye-aluminium isetshenziswe kabanzi ekudluleni kwemoto engasindi ngenxa yezinzuzo zayo njengokuminyana okuphansi, ukumelana nokugqwala okuhle nokucubungula kalula.
I-Aluminiyamu iyinsimbi elula ene-conductivity enhle kagesi kanye ne-thermal, kanye nokumelana nokugqwala okuhle.Ngesikhathi esifanayo, ukusebenza kwemishini ye-aluminium alloy kungcono kunezinto zensimbi zendabuko.I-Aluminium inephuzu lokuncibilika eliphansi.Izinga lokutholwa kwe-aluminium phakathi nayo yonke inqubo yokusetshenziswa nokugaywa kabusha alikho ngaphansi kwama-90%.Ingxubevange ye-Aluminium inokuphindaphindeka okuhle kakhulu, ngakho-ke ingxubevange ye-Aluminium njengamanje iyimpahla ekahle kakhulu yokubona isisindo esingasindi sezimoto.
Ukusetshenziswa kwezingxenye ze-aluminium alloy ezimotweni kunganciphisa ngempumelelo isisindo sayo yonke imoto, kwehlise isikhungo samandla adonsela phansi emoto, futhi kubone ngempela isisindo esingasindi semoto.Ngemuva kokuthi isisindo semoto sincishisiwe, ukusebenza kokusheshisa kwemoto kuzothuthukiswa ekushayeleni imoto, futhi imoto izozinza futhi ikhululeke, futhi umsindo nokudlidliza kuzothuthukiswa.
Ukusetshenziswa kwe-aluminium alloy ku-automobile lightweight ikakhulukazi kuhlanganisa i-aluminium alloy forgings, i-metal die castings, i-aluminium alloy extrusion nemikhiqizo yokudweba, njll.
I-Cast aluminium alloy isetshenziswa kabanzi enqubweni yamanje yemoto engasindi.Isetshenziswa kakhulu injini yemoto, chassis, wheel hub nezinye izakhiwo.Injini ibizwe ngokuthi "inhliziyo" ingxenye yemoto, ekhanda le-cylinder, i-cylinder block, i-piston, njll. Ukusetshenziswa kwe-aluminium alloy ezingxenyeni akukwazi nje ukunciphisa ngempumelelo isisindo sonke senjini, kodwa futhi kuhlakaze amandla ukushisa okukhiqizwa emsebenzini wenjini ngesikhathi esifanele ukuze kuthuthukiswe ukusebenza kahle kwenjini
Ukushisela kweshidi le-aluminium ingxubevange kubi kakhulu kunokwensimbi ngesikhathi sokusetshenziswa, okuthuthukisa ukusebenza kokushisela kanye nekhwalithi yokushisela yeshidi le-aluminium alloy, futhi kwandisa uhla lwesicelo se-aluminium alloy.Ukusetshenziswa kobuchwepheshe bokwenza okushisayo, ubuchwepheshe bokwenza i-superplastic kanye nobuchwepheshe bokwenza izinto ngokuqondana kwe-electromagnetic ukuze kuthuthukiswe ukwakheka nokwenza ikhwalithi yamaphaneli e-aluminium alloy.
Njengamanje, ngaphezu kwezinto zensimbi ze-aluminium alloy zendabuko, izinto ezihlanganisiwe ezisekelwe ku-aluminium zisetshenziswe kabanzi ekukhiqizeni izimoto ezingasindi ngenxa yezinzuzo zazo zokuminyana okuphansi, amandla aphezulu, nokumelana nokugqwala okuphezulu.Uma kuqhathaniswa namapiston ensimbi avamile, ama-piston enjini yezimoto anciphisa isisindo sawo cishe ngo-10%, kuyilapho ukusebenza kwawo kokukhipha ukushisa kukhuphuka izikhathi ezi-4.Ikhawulelwe amanani kanye nokulawulwa kwekhwalithi yokukhiqiza, izinhlanganisela ezisuselwe ku-aluminium azikakakhi isilinganiso esikhulu, kodwa zibonise ukusebenza kwazo okuhle kakhulu kwezinye izingxenye zezimoto.
Entuthukweni yanamuhla esheshayo yezomnotho nezenhlalakahle, ebhekene nezinkinga ezintsha zamandla kanye nezinkinga zemvelo, izimoto ezingasindi zingathuthukisa ngempumelelo ukusebenza kahle kukaphethiloli ezimotweni, ngaleyo ndlela zinciphise ukungcola.Enqubweni yokukhanya kwezimoto, ama-alloys e-magnesium, ama-aluminium alloys nezinye izinto zensimbi zisetshenziswe kabanzi ngenxa yezinzuzo nezici zazo.Ngokuzayo, ukuthuthukiswa kwezobuchwepheshe kuzosetshenziselwa ukunciphisa izindleko zempahla, ukwandisa ukusetshenziswa kwezinto ezibonakalayo, nokuthuthukisa izinto ezivumela imvelo nezingenzeka.Izinto ezintsha ezigaywa kabusha ziphinde zibe yinkambiso engagwemeki ocwaningweni nasekuthuthukisweni kwe-automobile lightweight.
