基于新型压电摩擦阻尼器的半主动控制及优化研究

摘要

为了研究压电变摩擦阻尼器的半主动控制效果，基于压电陶瓷管状驱动器设计了一种新型的压电摩擦阻尼器，并对所建立的空间杆系结构模型结合遗传算法确定了该阻尼器的最优布置数量及位置。最后对该模型进行了半主动控制仿真实验，得出此模型布置2个阻尼器时能达到较好的控制效果。%In order to study the effect of piezoelectric friction damper' semi-active control, a new type of piezoelectric friction damper is designed based on the piezoelectric ceramic driver. Through the establishment of the space truss structure model and by using genetic algorithm, the optimal number and position of the damper are determined. Finally, the simulation experiment about semi-active control is done according to the model, obtaining that the model could gain the better control effect when decorating two dampers.
