摘要
本文在文 [4 ]的基础上 ,按“有无复合体”模型对应力约束下多工况平面连续体结构拓扑优化的求解进行研究 ,提出了“工况影响系数”的概念 ,用于“病态荷载”问题的识别和解决 ,获得了令人满意的数值结果。
Based on the reference[4], the topological optimization problem of plane continuum structure under multi\|loading case with stress constraint has been solved according to the exist\|null combination model. The effective coefficient of loading case is proposed to identify and deal with the ill load problem. The computational results are satisfactory.
