摘要

提出减震结构被动控制系统优化分析数学模型，结合优化模型特点与主要优化算法的数学原理，选取模式搜索算法进行结构减震被动控制系统参数优化分析。通过编制目标函数程序，实现了Matlab模式搜索工具箱与Ansys减震模型的接口。多峰值函数的极值求解过程印证了模式搜索工具箱在解决该类优化问题时的有效性，而框架减震模型参数优化分析过程表明了优化程序的可行性以及优化结果的准确性，最终不同地震波下的优化分析结果证明了优化程序在减震结构参数优化中的稳定性。

Abstract

The thought of research on vibration control of construction is given out and corresponding mathematical model is established. Based on the model characteristics of optimization of seismic reduction structure and mathematical principle of main optimization algorithm, pattern search algorithm is chosen for damper parameter optimization analysis. Through secondary development of ANSYS, damper parameter optimization program of seismic reduction structure is established. Through searching for extreme value of one multi-peak functions pattern search algorithm is established to be effective. The results show the optimization algorithm of this paper and corresponding program can realize the parameter optimization analysis effectively and accurately. At last process of optimization analysis under different seismic waves proved the stability of the algorithm.
