Hauv kev ua haujlwm ntawm cov txheej txheem stamping nyuaj, ib pab neeg tshawb fawb tau koom tes nrog Tuam Tshoj Railway 16th Bureau Group los daws cov teeb meem cuam tshuam nrog kev siab - kev tsheb ciav hlau ceev - rooj formwork-tshwj xeeb nws cov duab geometry, sib sib zog nqus thiab tsis sib npaug ntawm qhov tob, thiab muaj kev cuam tshuam rau kev tawg thiab wrinkling. Los ntawm kev sib koom ua ke ntawm cov ntawv hlau ua txoj kev xav nrog cov lej simulation software, pab pawg tau ua tiav thawj zaug hauv tsev tsim tawm sib sib zog nqus- txheej txheem kos duab thiab cov txheej txheem tuag, uas tau xa mus rau Beijing-Tianjin High-Speed Railway; Cov kev tshawb fawb ntsig txog kuj tseem suav nrog cov ncauj lus xws li mos- cov cuab yeej tsim rau Audi B- ncej vaj huam sib luag.
Hais txog finite element simulation thiab tsom xam ntawm nyias steel ntawv stamping, cov kws tshawb fawb tau tsim ib qho qauv ANSYS finite element qauv los tshawb xyuas seb cov khoom theem hloov pauv cuam tshuam li cas rau cov qauv elastic thiab, yog li ntawd, tus cwj pwm springback thaum lub sij hawm stamping. Cov lej simulations muab cov ntaub ntawv ntawm kev ntxhov siab thiab kev sib txawv ntawm kev sib txawv thoob plaws hauv txoj kev tsim, muab lub hauv paus theoretical rau kev kwv yees thiab ua kom zoo dua cov ntawv hlau stamping.
Hais txog cov khoom siv thiab cov txheej txheem txhim kho, kub- stamped nyias steel ntawv yog hloov mus rau qib siab zog; thaum ib txwm kub-stamping steels feem ntau muaj lub zog tensile ntawm 1,500 MPa, cov kev hloov tshiab tshiab tau ua tiav 1,800 MPa thaum tuav qhov elongation ntawm kwv yees li 7.6%. Tsis tas li ntawd, kev siv cov thev naus laus zis tshiab- xws li dej txias ncaj qha - tau nce peb npaug kub - stamping ntau lawm efficiency.
