基于MSC.Marc接口的遗传算法结构优化设计

Genetic Algorithms Structural Optimization Design System Interfaced with MSC.Marc

提出了一种结构优化设计系统,该系统采用C语言和FORTRAN语言混合编写而成 在应用遗传算法的基础上,构建了与Marc模块的应用程序接口,直接调用Marc进行有限元分析,实现对目标体的结构优化设计 此系统被应用于车体优化设计中,取得了成功,充分说明该方法是正确。

This paper proposes a structural optimization design system which is programmed in C and FORTRAN. In order to conduct the optimization of target structure,this system, based on genetic alogorithms, designs an application interface with Marc Module and through which Marc can be used to calculate FEA directly. The system is successfully applied to bodywork optimization design, and shows that the design method is precise and effective.
