基于进化策略有频率禁区的结构优化设计方法
Structural optimization design method with frequency forbidden zone using evolution strategy
摘要
Abstract
For depart frequency bandwidth, the method is to adjust component sections or nodes’coordinates to change the dynamic characteristics on premise of static intensity being satisfied, so called optimization design of truss structure with frequency forbidden zone. Covariance Matrix Adaptation Evolution Strategy(CMA-ES), which is a global optimization algorithm with the advantages of high efficiency and robustness, has become a powerful tool for solving highly nonlinear multidimensional optimi-zation problems. Combining finite element method, an optimal method of truss structure with frequency forbidden zone based on CMA-ES algorithm is proposed. The results of examples show that the method is feasible and has the merits of excellent global optimization performance and efficiency compared with traditional and Particle Swarm Optimization(PSO)method.关键词
