摘 要: 首次将和声搜索算法(harmony search algorithm,HSA)引入结构健康监测领域,并成功应用于结构有限元模型修正.首先介绍和声搜索算法的基本原理及其主要计算步骤;其次将结构有限元模型修正转化为一优化问题,建立目标函数,利用和声搜索算法求解该优化问题,得到结构修正后的有限元模型;最后通过对5层剪切型框架模型进行仿真模拟,验证该方法在结构健康监测领域应用的可行性.拓宽和声搜索算法的应用范围,为结构健康监测提供另一种思路. The harmony search algorithm (HSA) was the first time introduced into the structural health monitoring, and applied to the updating of the structure finite element model. Firstly, the basic principle of harmony search algorithm and its main calculation procedure were introduced, then, the structural finite element model updating was transformed into an optimization problem, its objective function was estab- lished, and the harmony search algorithm was used to solve this optimization problem. Finally, the feasi- bility of the application of this harmony search algorithm in structural health monitoring was verified by using a five-floor shear-frame model for simulation, so that the application scope was enlarged, providing another way to treat structural health monitoring.
