Hauv ib lub tsheb, koj tuaj yeem pom ntau hom hlau siv.
Lub chassis, kis tau tus mob, axles, saloon cheeb tsam, load lub cev, thiab lwm yam yog ua los ntawm txawv composites ntawm hlau.

Hom steel siv hauv tsheb tsim:

Advanced high-strength steel (AHSS): hom no yog 10% sib dua li cov hlau me me thiab muaj zog dua. Nws yog siv thoob plaws lub cev tsheb.

Stainless hlau: dav siv nyob rau hauv tsheb. Tshwj xeeb tshaj yog nyob rau hauv Bus lub cev thiab tsheb thauj khoom. Feem ntau nyob rau hauv cov pa tawm thiab lwm qhov chaw uas raug mob hnyav

High-strength low-alloy (HSLA) hlau: feem ntau yog rau cov thav ntawv vim nws muaj zog, tsim tau, thiab tus nqi qis.

Ultra-siab zog steel (UHSS): nruj thiab tiv taus kev cuam tshuam.

Galvanized hlau: nws yog xeb-resistant thiab tuaj yeem ua rau 80% ntawm lub tsheb.

High carbon hlau: siv rau thav duab, chassis, qhov rooj vaj huam sib luag, thiab kev txhawb nqa beams raws li nws tiv taus hnav thiab tsim kua muag.

Qhov zoo ntawm steel nyob rau hauv automotive manufacturing

Rau lub cev tsheb,qis carbon steelfeem ntau yog qhov kev xaiv tsim nyog tshaj plaws. Nov yog vim li cas:

Formability: Cov pa roj carbon tsawg (tseem hu ua cov hlau me me) muaj cov ductility zoo heev, ua kom yooj yim rau hauv cov duab uas xav tau rau lub tsheb lub cev.

Weldability: Nws tuaj yeem ua tau yooj yim welded, uas yog qhov tseem ceeb rau kev sib sau ua ke ntau yam ntawm lub cev tsheb.

Nqi-zoo: Tsawg-carbon steel feem ntau tsis tshua kim dua li cov pa roj carbon monoxide siab lossis stainless hlau, ua rau nws muaj kev xaiv pheej yig dua rau kev tsim khoom loj.

Kev txiav txim siab hnyav: Txawm hais tias cov hlau tsis muaj roj carbon tsawg hnyav dua li qee qhov kev xaiv, lawv muab qhov sib npaug zoo ntawm qhov hnyav thiab lub zog rau kev siv tsheb.

High carbon hlaufeem ntau yog nkig heev rau lub cev tsheb, vim tias nws tuaj yeem tawg hauv qhov cuam tshuam.Stainless hlaumuaj kev tiv thaiv corrosion zoo heev tab sis yog kim dua thiab tsawg dua cov pa roj carbon tsawg, ua rau nws tsis tshua muaj rau kev siv lub cev tsheb. Txawm li cas los xij, stainless hlau tuaj yeem siv rau hauv cov ntawv thov tshwj xeeb, xws li cov tshuab tso pa lossis cov khoom siv trim, qhov kev tiv thaiv corrosion yog qhov tseem ceeb.

Vim li cas steel zoo dua aluminium rau tsheb ua:

Carbon fiber ntauib feem kev tsim kho thiab autoclaving tseem kim heev, vim tias tag nrho cov khoom yuav tsum tau txiav los ntawm cov ntaub thiab txheej hauv pwm uas tom qab ntawd yuav tsum tau txhaj tshuaj thiab muab tso rau hauv lub tshuab nqus tsev, suav nrog lub tsev tag nrho "crash plhaub / cell" (qhov twg tus tsav tsheb thiab cov neeg caij tsheb. nyob) ces muab tso rau hauv qhov cub loj thaum tseem nyob hauv lub tshuab nqus tsev. Ib qho autoclave loj txaus los ua txoj haujlwm no yog txwv tsis pub kim. Tsis tas li ntawd, cov neeg tsim khoom siv ntau qhov chaw CF muaj ntau yam xws li.

Cov pa roj carbon fiber ntau tuaj yeem deform, yog li nqus lub zog sib tsoo, feem ntau yam tsis muaj kev puas tsuaj.

Lawv yuav xav tau repainting, tab sis tsis tas yuav hloov.

Cov weaves nyob rau hauv cov fibers kuj muaj peev xwm tswj tau directionally, yog li ntawd tus tsim muaj peev xwm heev precisely coj cov kab ntawm quab yuam, qhov twg lub zog yuav mus nyob rau hauv ib tug sib tsoo.

Raws lialuminiumtsis yog fiber ntau, nws tsis tuaj yeem tsim los siv cov cuab yeej no. Txhua yam yuav raug rhuav tshem. Aluminium muaj zog thiab lub teeb txaus siv nyob rau hauv ntau qhov chaw ntawm tag nrho cov tsim ntawm lub tsheb, tshwj xeeb tshaj yog nyob rau hauv qhov chaw uas nws tsuas yog nyuaj heev los ua ib tug tsoos CF ib feem.

Kev nce qib tau ua rau carbon fiber txij li McLaren F1, uas yog 'Carbotanium'.

Raws li nws suab, qhov no yog ib qho weave ntawm carbon fiber uas muaj titanium strands interwoven.

Thiab nws yog* 10x muaj zog *tshaj li tus qauv carbon fiber.

Ntau thaj chaw ntawm a"tus qauv"(hauv cov lus hais vim tsis muaj qhov raug) lub cev lub tsheb yog tsim los ntawm 22 lossis 24- ntsuas cov ntawv txias dov, feem ntau galvanized lossis nrog qee qhov kev tiv thaiv corrosion ntxiv. Qee tus siv cov khoom kub-dov, qee qhov siv txhuas ntawm cov hlau sib txawv, qee qhov siv hunks ntawm magnesium ntawm no thiab muaj, thiab ib txhia siv stainless hlau.

Tus thawj VW Beetle yog tag nrho cov sib npaug thiab cov khoom, vim li ntawd, cov khoom siv tuaj yeem ua tau ntau dua li cov tsheb nrog cov npoo loj. Qhov no txhais ua lub teeb, lub tsheb pheej yig.

Hauv kev xaus, ib tsev neeg ntawm cov ntaub ntawv tsis muaj zog dua lwm tus. Cov tsev neeg ntawm cov hlau tsis muaj steel muaj xws li cov ntaub ntawv uas tawv thiab mos, muaj zog thiab tsis muaj zog, hloov tau yooj yim thiab nruj, thiab tus nqi sib tw thiab kim heev. Yog li cov tsev neeg ntawm carbon steels. Hloov chaw, koj yuav tsum xaiv raws li tus neeg tsim qauv tsim los ntawm txhua daim ntawv thov.
