离散变量结构优化的拟满应力设计方法

AN IMITATIVE FULL-STRESS DESIGN METHOD FOR STRUCTURAL OPTIMIZATION WITH DISCRETE VARIABLES

  • 摘要: 本文以满应力设计思想为基础,提出了适用于离散变量结构优化设计计算的拟满应力设计方法。该方法能直接计算具有应力约束和截面尺寸约柬的离散变量结构优化设计问题,也能处理同时具有稳定性约束和位移约束的多工况、多约束、多变量的离散变量结构优化设计问题。算例结果表明,拟满应力设计方法对于离散变量结构优化计算是非常有效的。

     

    Abstract: An imitative full-stress design method was presented for structural optimum design with discrete variables. The structural optimum design with discrete variables under stress and section size constraints can be directly calculated by this method, and the structural discrete optimization with multi-loading, multi-variable and multi-constraint (including stability and displacement constraints) can also be dealt with by using the indtative full-tress design method. The method was illustrated by two numerical examples. The results of the examples show that the method is efficient.
