基于EFG法和遗传优化算法的结构形状优化研究

STUDY ON STRUCTURAL SHAPE OPTIMIZATION USING ELEMENT-FREE GALERKIN METHOD AND GENETIC OPTIMAL ALGORITHM

中文摘要英文摘要

本文将无网格Galerkin法(Element-Free Galerkin Method—EFGM)和改进的Matlab遗传算法工具箱(Matlab Genetic Toolbox—MGT)相结合,提出了一种新的连续体结构形状优化设计方法。并针对形状优化设计的特点,建立了一种规则网格与有限元网格混合的EFG积分背景网格法。详细介绍了M函数文件的修改方法,以处理Matlab遗传算法工具箱不能直接施加的非线性与隐性约束条件。最后,完成了一个工程实例的结构形状优化,所得结果显示了该方法是可行的。

Integrating Matlab Genetic Toolbox with Element-Free Galerkin Method, a novel approach to continuum-based structural shape optimization problem is presented in this paper. According to the characteristic of shape optimization, a method combining regular mesh with element mesh is recommended. Thoroughly introduce the approach how to modify the M file to impose no-linear, implicit constraint that GAT can’t directly do. The results of the example, a practical optimization problem of connecting rod, show the feasibility of the approaches introduced.
