结构优化设计的几个方法

Several Methods for Structural Optimization

摘要: 本文阐明作者提出的几个结构优化设计方法。全文分为四部分。第一部分给出复杂结构满应力设计的浮动指数法、冻结内力法和拱坝的满应力设计方法,利用这些方法可对各种复杂结构进行满应力设计。第二部分给出一个边界搜索法,收敛速度较快。第三部分给出结构几何优化的混合方法。第四部分给出结构重分析的内力线性化方法,和两阶段优化方法。

Abstract: In this paper the author proposed several methods for structural optimization, namely: the method of fully stresssed design of complex structures such as the double-curvature arch dams, the method of boundary tracking, the mixed method for shape optimization of structures, the method of approximate structural analysis and the method of optimizing in two stages.
