【摘要】 渐进结构优化法(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。其原理是通过将结构中无效或低效的材料逐步去掉,使剩下的结构逐渐趋于优化。与其它优化方法相比,该方法原理简单,计算效率高,工程应用方便。本文阐述了渐进结构优化法的基本原理和具体步骤,并按照各种约束条件详细介绍了该方法在国内外的研究进展和典型范例。更多还原

【Abstract】 Evolutionary Structural Optimization(ESO) is a new arising numerical approach for optimization of various types of structures.The basic idea of ESO is removing inefficient material step by step,making the remaining structure evolve towards an optimum.Compared with other optimizing methods,the ESO has simpler principle,higher efficiency for structural optimization,and more convenient implementation in engineering applications.This paper elaborates the theories,procedures,investigation progress and typical numerical examples of this method according to different kinds of constraints.更多还原
