摘要
本文探讨了空间网格结构优化设计中遗传算法的应用,并利用遗传算法的并行性、全局优化性以及可操作性等特点,建立空间网格结构的优化设计模型,寻求各设计参数的最佳匹配.最后通过三杆平面桁架的数值例题来验证遗传算法应用的可行性和有效性.
This paper investigates the application of Genetic Algorithm(GA)in the optimum design of space grid structures. With GA's characteristic of running side by side,the overall optimization and feasible operation,the optimum design model of space grid structures is established,and the optimum matching of the design variables is obtained.A numerical example for the three bar truss is given to demonstrate the reliability and feasibility of GA's application.
