【摘要】 本文针对桁架结构优化设计时存在多种离散变量和多种约束条件的情况,将改进的离散变量直接搜索方法与结构有限元分析相结合,形成了适用于桁架结构设计的优化方法MADOP,同时研制了该方法的应用软件。通过对两个桁架结构优化设计表明,本方法是十分有效的。更多还原

【Abstract】 For optimum design of truss which exist various discrete Variablcs and various restiaincd conditions, lascd on improvement of the method for scarching discrete variables and finite elements analysis, an effective method is developed, that is MADOP. And.the software of the method is formed. Computational results for two examples show that the method presented in this paper is very efticient.更多还原
