摘要
调谐质量阻尼器被广泛应用于高耸结构振动控制。为了提高阻尼器的减振效果,基于安全性要求,建立等效二次型性能指标;通过改进遗传算法,求得TMD阻尼器的最佳安装位置,从而提高TMD减振系统的减振效果。最后通过仿真实验验证优化的意义,并得出一些结论:对于塔筒结构减振控制,不仅要针对低阶振型进行控制,高阶振型的扭转振动也不容忽视。
Tuned mass damper is widely used in high-rise structure vibration control.In order to improve the effect of the vibration damper,based on the requirement of safety,the equivalent quadratic performance index was established;based on improved genetic algorithm,the optimal installation position of the TMD damper was gotten,so as to improve the vibration reduction effect of TMD damping system.Finally the optimization significance was verified through simulation experiments.Also some conclusions are:for structural vibration control of tower drum,not only low-order modes should be controlled,but also high order torsional vibration modes should not be ignored.
