[摘要]在传统渐进结构优化方法的基础上,对静力优化过程中应力准则的选取以及位移灵敏度的计算做了改进。改进后的渐进结构优化方法(ESO)具有更强的工程实用性。运用这一方法对特定荷载作用下的转换厚板进行了拓扑优化,优化结果给出转换厚板的传力路径,并为现有转换厚板的加强及其形式改进提供了指导。

Abstract:The selection of stress criterion and the calculation of displacement sensitivity have been improved based on the tradition evolutionary structural optimization (ESO). The improved ESO is more applicable for practical engineering. This method is applied for topology optimization of transfer slab with given load. The result can show the force transfer path of the transfer slab, and also can offer some guidelines for the reinforcement and improvement of transfer slab.
Keywords:improved ESO; transfer slab; topology optimization; force transfer path
