渐进结构优化法的基本理论及应用

THE THEORY AND APPLICATION OF EVOLUTIONARYSTRUCTURAL OPTIMISATION METHOD

  • 摘要: 渐进结构优化法(Evolutionary Structural Optimization,简称ESO)是近年来兴起的一种解决各类结构优化问题的数值方法。它是基于这样一个简单概念:通过将结构中无效或低效的材料一步步去掉,剩下的结构将逐渐趋于优化。ESO 的特点在于简单,通用,优化的结构可为桁架,刚架,板壳或三维连续体,优化的约束条件包括应力,刚度,位移,频率及临界压力。本文阐述渐进结构优化法的基本原理和具体步骤,并以一系列算例演示该法的计算机实施过程,文章最后介绍了 ESO 的最新进展。

     

    Abstract: Evolutionary Structural Optimisation (ESO) is a simple and robust numerical method for optimization problems of various structures. The basic idea of ESO is that by slowly removing inefficient material, the residual structure evolves towards an optimum. The significance of ESO is its simplicity and generality. It can be used for a wide range of structures including trusses, frames,plates/shells and 3D continua. The optimization constraints can be stresses,stiffnesses/displacements, frequencies or buckling loads.This paper introduces the theories,procedures and the latest techniques of ESO. A number of examples of engineering design problems are presented to demonstrate the capability and effectiveness of ESO.
