摘要

基于目前机械结构优化设计未充分考虑结构动态特性对综合性能的影响以及工程优化设计效率低下的问题,提出了响应面模型仿真实验方法。通过结合最优空间填充设计和Kriging插值思想构建机械结构优化设计初始代理模型,并利用试验设计方法、误差较大区域加密优化、近似最优解局部加密处理以及内外层更新迭代思想,建立了在局部区域和全局空间内都具有较高近似精度的Kriging模型。在此基础上,基于筛选优化算法和多目标遗传算法得到目标函数的Pareto最优解。最后用轻轨用轴桥结构优化设计实例验证了该方法的有效性。

Abstract

The response surface model simulation experiment method is proposed on the basis of the influence of the dynamic characteristics of the structure on the comprehensive performance and the low efficiency of the engineering optimization design. By combining the ideas of the optimal design of space filling and Kriging interpolation to construct the initial agent model for optimal design of mechanical structure,and by using experimental design method,the error is bigger regional encrypted local encryption processing optimization,the approximate optimal solution and iteration of ideas,both inside and outside layer updating is established both in local and global space with high approximation accuracy of Kriging model. On this basis,Pareto optimal solution of the objective function is obtained based on the filter optimization algorithm and the multi-objective genetic algorithm.Finally,an example is given to demonstrate the effectiveness of the method.
