基于混沌粒子群算法的结构可靠性优化设计
Structural reliability optimal design based on chaos particle swarm optimization
摘要
Abstract
For the premature convergence problem of the particle swarm optimization (PSO), the chaos particle swarm optimization (CPSO) was adopted to the theory of structural reliability optimization.Dynamically contracted search fields, both of the PSO and the chaos optimization's search properties were brought into full play.Optimization model minimized structure weight was established to meet the requirement of structural system reliability, and the structural reliability optimal design method was presented on the basis of CPSO.The optimization method was used to optimize frame construction.The results show that using the structural reliability optimal design can get much better results than those by the PSO and the best vector method.This optimization method is easy to implement, and it has better stability,moreover, this method has better practical value and exploitation ability in engineering problem.关键词
