摘要
采用弹塑性大变形有限元方法研究了几何形状和材料参数对“V”型零件翻边的影响;同时基于全量塑性理论及膜应变假定,推导了轴对称情况(管形件翻边)的解析计算模型,通过与有限元结果的比较,分析了解析模型的适用性.
A large deformation elastic plastic FEM model is employed to simulate the stretch flanging of V shaped sheet metal parts. The effects of geometry and materials properties on the forming are studied according to the calculated results. An analytical model for axisymmetric case (flanging tube) is developed based on the total strain theory and membrane assumption. Its applicability is demonstrated through comparison with FEM results.
