Q1: Cov ntsiab lus zoo ntawm kev siv txhuas daim hlau hauv lub tsheb tsim niaj hnub?
Aluminium daim hlau muaj peb cov txiaj ntsig tseem ceeb rau cov ntawv thov hauv tsheb:
Luj txo kev txo- Aluminium lub ntom ntom (2.7 g / cm³) yog 60% qis dua li cov hlau, ua kom}% kev txuag nyiaj hauv lub cev panels
Tsoo lub zog nqus dej- 5 xxx series alloys tuaj yeem nqus tau 2 x lub zog ntau dua li cov hlau me me
Corrosion Kuj- Cov Oxide Oxide Txheej Txom Nyem xav tau rau cov galvanization kim
Cov neeg siv hluav taws xob loj ceeb toom tshaj tawm 8-12% roj ua tau zoo thaum hloov cov hlau nrog txhuas hauv kev kaw panels.
Q2: Yuav ua li cas sib txawv txhuas alloy series ua nyob rau hauv cov ntawv thov hauv tsheb?
Kev ua tau zoo sib txawv los ntawm Alloy:
5xxx series(5052, 5182): Zoo tshaj plaws rau lub cev Panels vim muaj kev muaj peev xwm (txog 25% elongation)
6xXX Series(6061, 6082): Zoo tagnrho rau cov txheej txheem sib xyaw nrog T6 npau taws (tawm los dag zog ~ 250 mpa)
7xxx series(7075): Siv rau hauv kev nyab xeeb kev nyab xeeb (B-CTS, Bumper Beams)
Cov kev tsim kho tshiab muaj xws li al-mg-sc alloys uas ua ke nrog 5xxx formability nrog 6xxx muaj zog {}}
Q3: Yuav ua li cas cov txheej txheem tsim tsim kom muaj kev pab ntau yam lag luam?
Peb cov thev naus laus zis tseem ceeb:
Kev Sib Tw Kub(HFQ®): Tso cai sib sib zog nqus yam tsis muaj kev tawg rau cov fenders
SuperPlastic Taus(SPF): Tsim cov kab xeb complex rau cov khoom kim heev tsheb
Laser Vuam:
Fiber ntau laser vuam ua tiav 5m / min nrawm
Txo cov cheeb tsam hluav taws kub los ntawm 60% vs Mig
Cov txheej txheem no pab 0 {. 7mm nyias txhuas panels nrog cov kws kho hniav sib piv rau 1.2mm steel.
Q4: Cas ua cov phaj txhuas tsim kev cuam tshuam EV roj teeb kev ua tau zoo?
Cov kev xav tseem ceeb:
Kev Tswj Cov Thermal: Txhuas Cov Hluav Taws Xob Hlau Muab Khoom Siv Hluav Taws Xob Muab 3x zoo dua li cov hlau
Luj faib: Kev siv lub tswv yim txo qis tag nrho cov tsheb loj thaum tswj 50:50 qhov hnyav nyhav
Kev tiv thaiv kev sib tsoo: HoneyComb txhuas cov qauv nqus 35% kev cuam tshuam ntau dua lub zog
Tesla tus txheej txheem roj teeb siv 3mm 6000-}-koob daim hlau ua cov khoom siv thauj khoom-cov kab mob.
Q5: Dab tsi cov txiaj ntsig kev ruaj khov ua tau cov phiaj xwm txhuas daim hlau?
Peb qhov zoo tshaj plaws:
Rov qab tau: Automotive Txhuas muaj 90% + tus nqi rov ua dua tshiab
LifeCycle Emissions: Txhua kg ntawm txhuas txuag tau 20kg npib hla lub tsheb lub neej
Kev ua tau zoo: Niaj hnub smelters siv 60% tsawg zog tshaj 1990s cov qauv
BMW tshaj tawm lawv cov aluminium-incenticive I3 ua tiav 30% qis cradle-rau-ntxa emissions dua li steel sib npaug.
