基于LS-dyna求解器的多工步冲压成形仿真分析

LS-dyna solver based on the multi-stage metal forming simulation analysis

LS—dyna求解器的多工步冲压成形的仿真分析，并将冲压分析结果映射到碰撞模拟中，使的碰撞分的结果析更加贴近实际。

LS-dyna solver of multi-stage metal forming simulation analysis and results mapped to the collision stamping simulation, the results of the analysis of the collision points closer to reality .
