摘要：

Spring-back is an inevitable problem in sheet metal stamping forming, and is the research hot spot and difficulty in this field. Taking the sheet stamping forming finite element theory and the simulation method as foundation, the numerical simulation of stamping and spring-back for roof of automotive was carried out by using the Dynaform software. Based on the simulation results, the forming and displacement distribution of spring-back were analyzed. The result showed that no crackle and wrinkle happened during the course of sheet metal forming, there were some regions sinking on the panel, other rising, and sinking tendency greater than rising. In order to reduce the spring-back, the measure of controlling spring-back was concluded and proposed, and it provided a judgment of process-optimization for forming of automotive panels.
