摘要：

The application of ultra-high strength steel parts in automobile bodies is increasing in order to reduce the weight and to increase the impact strength. A hot stamping process combines the shape forming process together with the strength hardening process. The strength of hot stamped parts can reach about 1500MPa which cannot be produced by the other conventional sheet metal forming processes. In this paper, the physical phenomena of hot stamping process and the technology issues of CAE are discussed. Then, a CAE system for the multi-stage hot stamping process is developed in order to perform the simulation faster and more accurately. A center pillar formed by hot stamping is taken as an example and a multi-stage simulation for formability evaluation and hardness prediction is performed using the developed CAE system. The simulation results for temperature, thickness and hardness have a good agreement with experimental values.
