Raws li cov ntaub ntawv los ntawm Lub Koom Haum Automotive Engineers ntawm Tuam Tshoj hauv xyoo 2024, kev lag luam thoob ntiaj teb automotive sealing system tau mus txog qhov ntsuas ntawm 5.2 billion US dollars, nrog rau qhov sib piv ntawm cov khoom sib khi ntse nce mus txog 37%.

I. Kev Txhim Kho Cov Khoom Siv Seal: Kev Tshawb Fawb Peb Sab Hauv Cov Khoom Siv, Cov Txheej Txheem, thiab Kev Sib Koom Tes Txawj Ntse

Kev Hloov Pauv ntawm Cov Khoom Siv

• Ethylene – Propylene – Diene Monomer (EPDM): Ib yam khoom siv ib txwm muaj, nws tuaj yeem tiv taus qhov kub thiab txias txij li - 50 ° C txog 150 ° C thiab muaj kev tiv thaiv UV ntawm 2000 teev (cov ntaub ntawv los ntawm SAIC lub chaw kuaj mob). Txawm li cas los xij, nws muaj qhov tsis zoo ntawm lub neej sealing tsis txaus.
• Thermoplastic Elastomer (TPE): Cov khoom siv tshiab tiam tshiab. Tesla Model 3 siv cov qauv sib xyaw ua ke peb txheej (pob txha tawv + txheej ua npuas ncauj + txheej tiv taus hnav), ua tiav lub neej nqa ntawm 150,000 zaug, nce 300% piv rau EPDM.
• Cov Khoom Siv Sib Xyaws Kho Tus Kheej: BASF tau tsim cov thev naus laus zis micro-capsule uas tuaj yeem kho cov kab nrib pleb txog li 0.5 hli. Nws tau teem sijhawm kom raug teeb tsa rau hauv Porsche cov qauv hluav taws xob ntshiab hauv xyoo 2026.

Daim Ntawv Qhia Txog Kev Faib Pawg Qauv

Cov Txheej Txheem Tsim Khoom Txawj Ntse
●Volkswagen ID.7 siv laser positioning rau kev sib dhos, ua tiav qhov tseeb ntawm ±0.1 hli thiab tshem tawm 92% ntawm cov suab nrov tsa.
●Toyota lub TNGA platform modular tsim tau ua kom muaj kev txij nkawm zoo dua 70%, nrog rau lub sijhawm hloov ib feem tsawg dua 20 feeb.
II. Kev Tshuaj Xyuas Txog Qhov Zoo ntawm Daim Ntawv Thov Kev Lag Luam: Kev Nkag Mus Rau Hauv Kev Siv Tshuab Los Ntawm Lub Tsheb Thauj Neeg Mus Rau Cov Chaw Tshwj Xeeb
Tshiab - Lub Tsheb Siv Hluav Taws Xob
● Kev Sib Txuas Dej Tsis Pub Dej nkag: Lub ru tsev ntawm XPeng X9 siv cov qauv labyrinth plaub txheej, ua tiav xoom nkag mus rau hauv qab nag ntawm 100mm / h (tau ntawv pov thawj los ntawm CATARC).
●Kev Tswj Xyuas Kev Siv Hluav Taws Xob: Li L9 txo qhov kev siv hluav taws xob ntawm cov cav qhov rai los ntawm 12% los ntawm kev sib txhuam qis (μ ≤ 0.25).
Cov Xwm Txheej Tshwj Xeeb rau Lub Tsheb
● Cov Tsheb Thauj Khoom Hnyav: Foton Auman EST muaj cov khoom sib khi uas tiv taus roj, tswj tau qhov elastic modulus ntau dua 5MPa hauv qhov chaw txias heev ntawm - 40 ° C.
●Cov Tsheb Khiav Tawm Sab Nraud: Tank 500 Hi4 – T siv cov hlau uas muaj zog ntxiv, ua rau lub tsheb khiav tob txog 900 hli.
Kev Txuas Ntxiv ntawm Kev Tsim Khoom Txawj Ntse
●Bosch lub iSeal 4.0 system muaj 16 lub micro-sensor, uas ua rau muaj kev saib xyuas tiag tiag thiab kev kwv yees qhov xwm txheej ntawm kev sib khi.
●ZF lub blockchain traceability system tuaj yeem taug qab 18 yam tseem ceeb ntawm cov ntaub ntawv xws li cov khoom siv raw thiab cov txheej txheem tsim khoom.
III. Cov Lus Qhia ntawm Kev Hloov Pauv ntawm Kev Siv Tshuab: Kev Hloov Pauv ntawm Kev Lag Luam Uas Tau Los Ntawm Kev Koom Tes Ua Ke
Cov Txheej Txheem Sib Txuas Lus Ib puag ncig
Continental tau tsim cov khoom siv kaw uas tiv taus cov av noo nrog qhov dej nce txog li 15%, uas tau npaj yuav siv rau hauv Mercedes - Benz EQ series hauv xyoo 2027.
Cov Txheej Txheem Tsim Khoom Siv Tau Ntev
Covestro cov khoom siv TPU uas ua los ntawm cov khoom siv bio-based tau txo nws cov pa roj carbon dioxide los ntawm 62% thiab tau dhau daim ntawv pov thawj xa khoom rau BMW iX3.
Kev Siv Tshuab Digital Twin
Lub platform ANSYS simulation ua rau muaj kev sim virtual ntawm cov txheej txheem sealing, ua rau lub voj voog tsim kho luv dua 40% thiab txo cov khoom pov tseg los ntawm 75%.
Xaus lus
Txij li kev tsim cov qauv molecular ntawm cov ntaub ntawv mus rau kev sib koom ua ke ntawm cov txheej txheem sib txuas lus ntse, cov thev naus laus zis foob tsheb tau tawg hla cov ciam teb ib txwm muaj. Raws li Waymo cov neeg tsav tsheb tsis muaj neeg tsav tsheb tau hais txog tus qauv ruaj khov ntawm 2 lab lub voj voog, qhov kev sib tw thev naus laus zis no txog 0.01 - millimeter precision yuav txuas ntxiv tsav tsheb kev lag luam mus rau kev ntseeg siab dua thiab kev txawj ntse.
