利用遗传算法的结构优化设计

Optimum Design of Truss Structures by Using Genetic Algorithm

利用遗传算法，首次提出“取刚架截面形状和尺寸规格为设计变量，结构体积为目标函数，求全局最优解”这一代化模型．通过对各个计算环节的研究，确立了可行的计算方法，编制计算程序，并以算例证明该方法的有效性．

A optimum design method in which the optimum shapes and dimension of cross sectionsare selected to minimize the structural volume and get the global optimum solution, is presentedfirst by means of the method of the genetic algorithm. The numerical results show that the modelis valid.
