摘要
采用有限元模拟曲面壳体一次热拉深成形,壳体底部出现断裂,成形试验也与模拟结果一致。通过改进工艺方案,采用2次拉深成形并模拟,结果表明此方案可行,经试验对比,验证了模拟结果的正确性。
Breaking occurred in shell bottom in FE simulation of one step hot drawing forming cambered shell,which has been proved in test of forming.Improvement o f technology using two step drawing forming has been done and proved to be feas ible by results,which was proper verified in comparison test,of simulation whi ch has thus shown its guidance in technology flow planning and die design for in crease in work efficiency and reduction of cost.
