薄板优化设计的多阶段决策算子法

A Multistage Decision Operator Method for the Optimum Design of Thin Plate

本文在研究应用多阶段决策算子方法求解弹性薄板结构优化的问题中,运用了有限元的分析方法,按多阶段决策分析的需要推导了位移约束条件的表达式及状态转换方程式,成功地解决了离散变量的弹性薄板结构优化设计的问题。文中编制了薄板优化设计的计算机程序,给出了在微机上作出的计算例题。

In this paper, based on the conceptions of the multistage decision operator and the object function matrix and the analysis of finite element method, the optimum design of thin plate with discrete variables under the displacement constraints is solved successfully by using the multistage decision operator method. The computer program for the optimum design of the plate is coded, and a numerical example computed on microcomputers is given in this paper.
