Nekuwedzera kwekugadzirwa kwemotokari uye kutengesa, kushandiswa kwesimba uye kusvibiswa kwemhepo kunogadzirwa panguva yekugadzira uye kushandiswa kwemotokari kuri kuwedzera.Panguva imwe cheteyo, kushatiswa kwemhoteredzo kuri kuwedzerawo kukurumbira.Naizvozvo, kuitira kusimudzira kusimukira kwakasimba kweindasitiri yemotokari, pasi pechisungo chekuona kuomarara, simba, uye kuchengetedza kuita kwemotokari, nekushandura zvinhu zvechimiro chemotokari uye zvikamu, huremu hwemotokari hunoonekwa, izvo zvakakosha pakuvandudza kushanda kwemafuta emotokari uye kuderedza zvinosvibisa.Emissions ine yakakura kwazvo kukurudzira maitiro.Mota dzakareruka haingogone chete kuchengetedza simba uye kuderedza kubuda, asi zvakare inovandudza kugadzikana uye simba remotokari panguva yekutyaira.Ichi chinyorwa chinonyanya kutsanangura magnesium alloy uye aruminiyamu alloy, ari pari zvino anonyanya kushandiswa emotokari zviremu zvinhu, uye anoongorora maitiro azvo uye zvakanakira, pamwe neremangwana rekusimudzira maitiro emotokari lightweight.
Tichitarisa kubva kune yazvino budiriro maitiro, kuitira kuchengetedza nharaunda uye kuchengetedza simba nezviwanikwa, remangwana rekutsvaga mota uye budiriro inobhadhara zvakanyanya kune yakareruka dhizaini yemotokari.Kushandiswa kwezvinhu zvisingaremi sesimbi-yakasimba, aruminiyamu alloy, magnesium alloy, uye zvinhu zvinosanganiswa mukugadzirwa kwemotokari zvinogona kubudirira kuwana mota yakareruka.Pamusoro pezvo, maitiro ekugadzira epamberi akadai sekupisa kuumba, laser tailored welding, hydraulic forming, nezvimwe zvinogona kushandiswa zvakare.Motokari dzakareruka.Aluminium alloy yakashandiswa zvakanyanya mumotokari yakareruka ichipfuura nekuda kwezvakanaka zvayo senge yakaderera density, yakanaka corrosion resistance uye nyore kugadzirisa.
Aluminium isimbi yakareruka ine yakanaka magetsi uye yekupisa conductivity, pamwe nekunaka kwekusagadzikana.Panguva imwecheteyo, iyo machining performance yealuminium alloy iri nani pane iyo yechinyakare simbi zvinhu.Aluminium ine nzvimbo yakaderera yekunyungudika.Iyo yekudzoreredza mwero wealuminium panguva yese yekushandiswa uye kudzokorodza maitiro haisi pasi pe90%.Aluminium alloy ine yakanaka kwazvo kuberekana, saka Aluminium alloy parizvino ndiyo yakanyanya kunaka zvinhu kuona huremu hwemotokari.
Iko kushandiswa kwealuminium alloy zvikamu mumotokari kunogona kunyatso kudzikisa huremu hwemotokari yese, kudzikisa nzvimbo yegiravhiti yemotokari, uye kunyatsoona huremu hwemotokari.Mushure mokunge uremu hwemotokari hwaderedzwa, kukurumidza kwekuita kwemotokari kuchavandudzwa mukufambisa kwemotokari, uye motokari ichave yakanyatsogadzikana uye yakagadzikana, uye ruzha uye kudengenyeka kuchavandudzwa zvakare.
Iko kushandiswa kwealuminium alloy mumotokari lightweight kunyanya inosanganisira aluminium alloy forgings, simbi inofa castings, aluminium alloy extrusion uye zvigadzirwa zvekudhirowa, nezvimwe.
Cast aluminium alloy ndiyo inonyanya kushandiswa mune yazvino mota lightweight process.Inonyanya kushandiswa mumotokari injini, chassis, vhiri hub uye zvimwe zvimiro.Injini yakanzi "moyo" chikamu chemotokari, muhumburumbira musoro, cylinder block, piston, etc. Kushandiswa kwealuminium alloy kune zvikamu hakugone chete zvinobudirira kuderedza huremu hweinjini, asiwo kuparadzira kupisa kunogadzirwa muinjini kushanda panguva yakakodzera yekuvandudza kushanda kweinjini
Iyo weldability yealuminium alloy sheet yakashata kupfuura iyo yesimbi panguva yekushandiswa, iyo inovandudza welding performance uye welding mhando yealuminium alloy sheet, uye inowedzera huwandu hwekushandisa kwealuminium alloy.Kushandiswa kweinopisa yekugadzira tekinoroji, superplastic yekugadzira tekinoroji uye electromagnetic coincidence kugadzira tekinoroji yekuvandudza kuumbwa uye kuumba mhando yealuminium alloy mapaneru.
Parizvino, mukuwedzera kune echinyakare aruminiyamu alloy simbi zvinhu, aruminiyamu-yakavakirwa composite zvinhu zvakashandiswa zvakanyanya mukugadzira mota isina kuremerwa nekuda kwezvakanaka zvadzo zvekudzikira density, kusimba kwepamusoro, uye yakakwirira corrosion kuramba.Kuenzaniswa nemapistoni echinyakare ekukanda simbi, injini yemotokari pistons inoderedza huremu hwadzo ne10%, nepo kupisa kwavo kupisa kunowedzera ka4.Yakadziviswa nemutengo uye kugadzirwa kwemhando yekudzora, aluminium-yakavakirwa macomposites haisati yaumba chiyero chakakura, asi vakaratidza kuita kwavo kwakanakisa pane zvimwe zvikamu zvemotokari.
Mukusimudzira kwanhasi kwehupfumi nemagariro, kutarisana nematambudziko matsva emagetsi uye matambudziko ezvakatipoteredza, mota dzisina kuremerwa dzinogona kunyatso kuvandudza kushanda kwemafuta emotokari, nekudaro kuderedza kusvibiswa kwemhepo.Mukuita kwemotokari lightweighting, magnesium alloys, aruminiyamu alloys uye zvimwe zvinhu zvesimbi zvakashandiswa zvakanyanya nekuda kwezvakanakira uye maitiro.Mune ramangwana, kuvandudzwa kwetekinoroji kuchashandiswa kudzikisa mitengo yezvinhu, kuwedzera mashandisirwo emidziyo, uye kugadzira zvinhu zvine hushamwari uye zvinogoneka.Zvishandiso zvitsva zvinodzokororwa zvakare maitiro asingadzivisike mukutsvagisa uye kusimudzira kwemotokari yakareruka.
