摘 要

(西南交通大學土木工程學院,成都 610031)
[摘要]在傳統(tǒng)漸進結構優(yōu)化方法的基礎上,對靜力優(yōu)化過程中應力準則的選取以及位移靈敏度的計算做了改進。改進后的漸進結構優(yōu)化方法(ESO)具有更強的工程實用性。運用這一方法對特定荷載作用下的轉換厚板進行了拓撲優(yōu)化,優(yōu)化結果給出轉換厚板的傳力路徑,并為現(xiàn)有轉換厚板的加強及其形式改進提供了指導。
[關鍵詞]改進ESO;轉換厚板;拓撲優(yōu)化;傳力路徑

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
