有限元模型转换及其在金属板料成形数值模拟中的应用

Finite element model transformation and its application in sheet metal forming numerical simulation

本文根据CAD和CAE软件各自的功能和特点 ,探讨了板料成形数值模拟中CAD模型向CAE模型转换的方法 ;并针对有限元分析软件ANSYS与ABAQUS的实际特点 ,编写了有限元模型转换接口程序 ,用实例验证了所编接口转换程序的可行性与正确性。

According to the individual function and characteristic of different CAD and CAE software, the method of the model transformation from CAD to CAE in Sheet Metal Forming Numerical Simulation is discussed. Then, according to the factual characteristic of the Finite Element Analysis software ANSYS and ABAQUS, an interface program of finite element model transformation is compiled. Finally, an example is given to verify the correctness and validity of the program.
