Abstract

LS-DYNA and ANSYS software are adopted to simulate hot stamping and quenching processes of M-shaped 1038mm*1.85mm B1500HS automobile anticollision beam. Different stress distribution are obtained among different start temperature as 800 , 850 , 900 , 950 and different stamping velocity as 25mm/s, 50mm/s, 75mm/s and 100mm/s. The higher the start temperature, the better the metal formability; the higher the temperature at the end of forming, the smaller the flow stress. The faster the stamping velocity, the shorter the cooling time, and the lower the maximum flow stress. After optimization, the difference between the minimum and maximum temperature of forming part decreases from 74 to 47 , indicating that the temperature distribution after cooling is more uniformed.
