摘要

随着建筑结构向大型化发展,将智能材料应用于建筑结构的减震已经成为一个重要的研究领域,压电智能结构就是目前的研究重点之一.介绍了压电堆式驱动器,建立了结构在地震作用下的运动方程和基于LQG控制理论的最优控制方法.将驱动器布置在空间钢结构框架的底层柱上,并对其在地震激励下的反应进行了主动控制实验研究.结果表明,结构各层的响应均有不同幅度的降低,压电堆式驱动器可以有效地抑制和减小结构的地震反应.
With the large-scale development of building structures,It has become an important research field that intelligent materials are used in structural damping,and the piezoelectric intelligent structures is the focus of current research.In this paper,the piezoelectric stack actuator is presented.The structure's motion equation under earthquake and the optimal control method based on the linear quadratic Gauss control theory are established.The actuator is used for bottom columns in the space steel frame.The results of the active control experiment illustrate that the responses of each floor were decreased to different degrees and the piezoelectric stack actuator can effectively reduce the structural responses induced by the earthquake.
