Nrog rau kev txhim kho sai ntawm kev lag luam tsheb, tib neeg muaj cov kev xav tau siab dua thiab siab dua rau qhov ua tau, kev ntseeg siab thiab kev zoo nkauj ntawm cov vaj huam sib luag tsheb. Kev kos duab I-puab yog cov txheej txheem tseem ceeb tshaj plaws hauv cov txheej txheem tsim cov vaj huam sib luag lub cev. Seb nws tus qauv tsim nyog yuav txiav txim siab Nws cuam tshuam ncaj qha rau qhov zoo ntawm cov vaj huam sib luag tsheb thiab lub voj voog kev txhim kho ntawm cov qauv tshiab. Yog li ntawd,TTMtshuaj xyuas cov txheej txheem kos duab ntawm cov vaj huam sib luag tsheb, uas yog qhov zoo rau kev luv luvpwmlub sijhawm tsim qauv, txhim kho qhov zoo ntawm cov vaj huam sib luag, thiab yog li txhim kho kev sib tw ntawm cov tuam txhab. Daim ntawv no feem ntau qhia txog cov txheej txheem kos duab ntawm phab ntsa sab nraud vaj huam sib luag.

1.1 Cov ntaub ntawv siv rau cov vaj huam sib luag sab

Cov txheej txheem tsim ntawm lub vaj huam sib luag sab nraud ntawm phab ntsa sab feem ntau yog 4-5 kauj ruam (tsis suav nrog kev ua kom dawb). Yuav kom ntseeg tau tias cov khoom noodle zoo thiab txo qhov nyuaj ntawm kev debugging, feem ntau ntawm cov phab ntsa sab tam sim no ua tiav hauv tsib kauj ruam. Vim yog cov duab nyuaj ntawm phab ntsa sab thiab qhov tob ntawm kev kos duab, cov ntaub ntawv ntawv siv feem ntau yog DC56D + Z lossis DCO7E + Z + pre-phosphating nrog cov khoom siv kho tshuab zoo dua, thiab cov khoom tuab feem ntau yog 0.65mm, 0.7mm, thiab 0.8mm. Xav txog kev tiv thaiv xeb thiab kev tawv thiab kev ua tau zoo ntawm cov khoom, cov khoom siv nyiam yog DCDC56D + Z / 0.7t. Tib lub sijhawm, qhov tawg ntawm ciam teb ntawm qhov rooj qhib sab muaj kev sib raug zoo nrog lub kaum sab xis R ntawm cov kab khoom phem. Lub kaum sab xis R me dua ntawm qhov rooj qhib, qhov yooj yim dua rau ciam teb tawg.

1.2 Kev taw qhia ntawm phab ntsa sab nraud vaj huam sib luag

Xav txog cov txheej txheem kos duab ntawm lub vaj huam sib luag sab nraud, feem ntau qhov kev taw qhia ntawm lub vaj huam sib luag sab nraud ntawm lub vaj huam sib luag sab nraud yog nyob rau ntawm lub kaum sab xis ntawm 8-15 ° nrog rau Y kev taw qhia ntawm lub cev tsheb.

1.3 Cov ntsiab lus ntxiv rau kev saib xyuas hauv cov txheej txheem sab nraud ntawm phab ntsa

1.3.1 Cov ntsiab lus tseem ceeb rau kev teeb tsa cov duab ntxiv ntawm sab saud ntawm B-pillar

Muaj ob txoj kev teeb tsa rau kev kos cov nqaij seem ntawm lub ces kaum sab saud ntawm B-pillar. Ib qho yog kos cov kab sib cais ntawm lub punch ntawm lub ces kaum ntawm lub punch ze rau cov khoom zoo li cas, uas yog, hom R. Cov duab no ntawm cov nqaij seem tuaj yeem txo qhov chaw ntawm lub ces kaum sab saud. Qhov tuab thiab qhov thinning ntawm cov khoom tuaj yeem hloov kho kom tiv thaiv kev tawg. Qhov thib ob yog teeb tsa cov kab sib cais ntawm lub punch ntawm lub ces kaum ntawm lub punch kos duab rau ib txoj kab ncaj, uas yog, ib txoj kab ncaj. Cov duab no ntawm cov nqaij seem tuaj yeem txhim kho qhov formability ntawm lub ces kaum sab saud thiab nres Qhov saum npoo ntawm lub B-pillar yog deformed.

1.3.2 Cov ntsiab lus uas yuav tsum tau saib xyuas thaum teeb tsa cov duab ntxiv ntawm cov txheej txheem ntawm qhov chaw qhib qhov rooj

Cov kab sib cais ntawm qhov qhib qhov rooj yuav tsum hloov pauv linearly ntau li ntau tau, thiab qhov kev hloov pauv yuav tsum tsis txhob ntse lossis tig

1.4 Kev teeb tsa ntawm cov hlua khi rau ntawm phab ntsa sab nraud

Vim yog cov duab ntawm phab ntsa sab uas nyuaj heev, txhawm rau kom tswj tau cov khoom ntws hauv txhua qhov, feem ntau siv ob lub tav. Txhawm rau kom tiv thaiv cov hlua rub kom tsis txhob nkag mus rau hauv qhov chaw ntawm cov khoom thiab cuam tshuam rau qhov zoo ntawm cov khoom, qhov deb ntawm cov hlua rub thiab cov khoom ze ntawm qhov chaw yuav tsum tau nthuav dav, thiab tom qab ntawd qhov chaw ntawm cov hlua rub yuav tsum tau kho los ntawm CAE simulation kev tshuaj xyuas siv Autoform software. Cov hlua rub hauv qhov qhib qhov rooj yuav tsum du li sai tau, thiab lub kaum sab xis R yuav tsum loj li sai tau.
