Abstract：

LS-DYNA software was adopted to conduct numerical simulation analysis of hot stamping for front bumper. The temperature field distribution, stress field distribution, reduction rate distribution and FLD in the course of hot stamping under the two types of friction conditions were calculated，and the formability of parts was predicted. Based on the simulation，the hot stamping mould was developed，and the front bumper components of hot forming were stamped. Compared the test results with the simulation, both the results coincide basically with same variation trend. The results show that the friction state has a great impact on formability of hot stamping technology for parts.
