模拟板金冲压成形的计算机软件系统

SOFTWARE SYSTEM FOR SHEET METAL FORMING SIMULATION

ＳＭＦＳＳ１由模具设计的ＣＡＤ模块、前处理模块、成形过程仿真模块和后处理模块及接口组成。仿真模块使用有限元方法对成形过程中的接触问题采用了接触搜寻法确定接触对，并使用罚参数法快速准确地求出接触力。前后处理模块使ＣＡＤ系统与仿真模块构成统一的应用系统，应用效率与方便性良好。通过应用实例说明软件的实用性及可应用性。

SMFSSI refers to software system of the sheet metal forming simulation system-1. It consists of sheet metal forming die design model (CAD)preprocessor post interface and finite element method(FEM)model. The forming process is simulated with FEM code. The slave/master contact node searching makes system fast. The panel factor is used for solving accurately. Preprocessor and post interface make system effective and convenient. Some application examples are given.
