摘要
本文提出结构优化的一种广义优化准则法，分别把Chen的优化准则法和Heo的子结构灵敏度综合延伸到重特征值场合，并借助设计向量的广义变分改进了Czyz的方法．
This paper presents a generalized optimality criterion method for structural optimization. Extensions are made respectively to Chen's method for optimality criterion and Heo's method for substructural sensitivity synthesis to allow the treatment of multiple eigenvalue case,and Czyz's approach is improved by means of generalized variation of the design vector.
