【摘要】 采用有限元动态分析技术,采用HILL屈服准则,模拟了板料拉深成形的过程,结合实验拉深进行比较,模拟结果与实验数据符合。应用0.618一维搜索优化方法,在数值模拟中对压边力进行了优化,为实验中压边力的确定提供了参考数据。更多还原

【Abstract】 A sheet metal forming of transversely anisotropic materials is simulated with 3D dynamic elastic-plastic finite element method, and the final shape and the Forming Limit Diagram are got. The results of simulation coincide with the facts well. The blank holder force is optimized and the results can be used as reference of the experiments.更多还原
