Cov tsheb yog tsim los ntawm kaum tawm txhiab tus neeg sib xyaw ua ke, thiab cov khoom xaiv rau txhua qhov kev cuam tshuam ncaj qha cuam tshuam rau lub tsheb ua haujlwm, kev nyab xeeb, kav ntev, thiab nqi. Nrog kev nce qib hauv cov ntaub ntawv txuj ci, niaj hnub cov khoom siv hluav taws xob tsis muaj txwv rau cov hlau tsoos hlau. Hloov chaw, lawv tau tsim cov toj roob hauv pes ntau yam, feem ntau hlau- raws li, nrog ntau cov ntaub ntawv siv hauv synergy. Kab lus no yuav muab ib qho in -} qhov tob tob ntawm cov khoom siv thiab cov khoom siv hauv cov khoom siv tsheb loj.
I. Steel: Lub Pob Txheem Ntawm Kev Raug Kho Automotive
Cov hlau tseem yog cov khoom siv feem ntau cov khoom siv hauv kev tsim khoom lag luam, cov nyiaj txiag rau kwv yees li 60% -70%. Nws lub zog siab, yooj yim ntawm kev ua, thiab tus nqi qis ua rau nws xaiv qhov uas xav tau rau lub cev, chassis, thiab powertrain Cheebtsam.
High - lub zog hlau (hss) thiab advanced high {1} {muaj zog hlau (ahs)
Siv nyob rau hauv kev nyab xeeb rau kev nyab xeeb xws li lub cev ntas thiab qhov rooj cuam tshuam cov kab teeb ci rau 500}}}, txo qhov hnyav thaum txhim kho kev nyab xeeb. Piv txwv li, dual-theem steel (DP hlau) thiab MARTENITITIC steel yog siv nyob rau hauv A / B CTS thiab Bumers.
Galvanized steel ntawv
Galvanized steel ntawv yog dav siv nyob rau hauv lub cev panels (xws li lub qhov rooj thiab hoods) kom txuas ntxiv nws lub neej kev pabcuam vim nws xeb {}} resistant nto.
Nrum Hlau
Vim nws cov khoom lag luam zoo heev thiab poob siab qhov nqus tau cov khoom siv, nws feem ntau siv hauv cov khoom siv xws li cov cav ntoo thiab nres tsheb. Grey cam khwb cia hlau yog tsawg {{1} Tus nqi}} tus nqi, thaum cov hlau du, ua rau nws thauj khoom zoo xws li crankshafts.
Ii. Aluminium Alloy: cov khoom siv dag zog ua rau
Nrog lub ntom ntom tsuas yog ib -}}}}} tus thib peb ntawm cov hlau tab sis lub zog zoo sib xws, Alloy Alloy yog cov khoom tseem ceeb rau lub tsheb loj. Txhua txhua phaus ntawm aluminium alloy siv nyob rau hauv qhov chaw ntawm cov hlau txo qhov hnyav los ntawm kwv yees li ib phaus thiab txhim kho kev siv roj.
Cov Cheebtsam cov khoom sib xyaw: lub tog raj kheej hau, pistons, thiab lwm yam siv cov txhuas alloy kom txhim kho cov kev tsis txaus siab.
Lub cev thiab chassis: high -}}}}} Tus qauv teskine lub cev sib xyaw ntau dua 90% aluminium alloy.
Cov log: 6061 lossis 7075 Series Aluminium Log Muaj Kev Sib Tw Ntawm Lub Hnav Thiab Compostsics Thiab Composites: Kev tawg ua haujlwm thiab tsim qauv
The proportion of engineering plastics and composites used in automobiles has increased annually, primarily in non-structural parts, but is also gradually expanding into functional components.
Nquag plastics
Polypropylene (PP): Bumpers thiab sab hauv lub tshuab txiav, tus nqi qis thiab yooj yim rau pwm.
Polyurethane (PU): Lub rooj ua npuas ncauj thiab suab rwb thaiv tsev, muab kev nplij siab.
Nylon (PA): lub tshuab siv hluav taws xob (xws li kev ua kom muaj kev nkag), tiv taus siab {}} kub roj corrosion.
Carbon Fiber txhawb koob Regerfed Yas (CFRP): Nrog rau cov qauv ntawm BMW (xws li tshem tawm cov qauv BMW I3}
Iav Fiber Reinle Reinterced Yas (GFRP): Siv rau sab nrauv cov cheebtsam xws li ru tsev thiab lwj, ntsuas lub zog thiab tus nqi.
4. Roj hmab thiab elastomers: qhov indispensable "mos" lub luag haujlwm
Cov log tsheb: Composites ntawm cov roj hmab muaj roj hmab thiab hluavtaws hluavtaws (xws li styrene {}} butadiene roj hmab) yuav tsum sib npaug hnav tsis kam, tuav, thiab kev laus tsis kam. Ntsaws thiab ceeb tuaj ua: ethylene propylene diene monomer (EPDM) yog siv rau lub qhov rooj ntsaws, thiab cov roj hmab muaj rau kev ncua rau bushings.
V. Cov Khoom Siv Tawm: cov thev naus laus zis ntawm yav tom ntej auto
Magnesium alloy: sib dua tshaj txhuas (nrog ib qho ntom ntom (nrog lub ntom ntom nti (nrog ib qho ntom nti ib {3, nws yog siv nyob rau hauv kauj thaib hau, tab sis yog kev ntxim rau kev xeb.
Ceramics: Siv hauv Spark Plug insulators thiab turbocharger bearings, lawv muab siab heev - kub kuj.
Cov khoom siv 3D luam tawm: titanium alloys, nylon hmoov, thiab lwm yam ntaub ntawv siv rau kev tsim cov khoom sib xyaw ua ke.
Tag
Cov kev xaiv ntawm cov ntaub ntawv hauv cov khoom lag luam yog kev sib npaug ntawm kev ua tau zoo, qhov hnyav, thiab tus nqi. Yav tom ntej, nrog kev nce qib ntawm lub zog tshiab thiab ntse thev naus laus zis, xws li cov ntaub ntawv graphene, thiab rov ua dua lub chaw tsim khoom lag luam hauv tsheb. Nkag siab cov ntaub ntawv no tsis yog qhov tseem ceeb rau cov neeg siv khoom tab sis kuj tseem pab tau kev nkag siab txog kev txhim kho cov thev naus laus zis thev naus laus zis.
