| 摘 要： | 将参数化网格划分系统ParaMesh和网格模型转换接口程序应用于参数化有限元分析(PFEA)和优化设计之中。通过ParaMesh建立了参数化有限元模型并进行参数化有限元分析。把人工神经网络(ANN)和遗传算法(GA)相结合进行优化设计,研究了U形件翻边成形中的板料形状优化。利用优化的结果值进行验算,获得了良好的成形件,表明基于PFEA、ANN和GA进行成形板料形状优化是可行的。

| Abstract: | The parameterized mesh partitioning system,i.e.ParaMesh and grid model conversion interface program were applied to the parameterized finite element analysis(PFEA)and optimization design.ParaMesh was used for the establishment and analysis of finite element model,and artificial neural network(ANN)and genetic algorithm(GA)were combined for the optimization design of U-shaped sheet bar flanging.Good shaped objects were obtained from optimized computations. |

| Keywords: | parameterized finite element analysis(PFEA) artificial neural network(ANN) genetic algorithm(GA) optimization |
