摘要

在压电摩擦阻尼器力学性能试验的基础上，对一安装有压电摩擦阻尼器的模型结构进行了地震模拟振动台试验研究。利用MATLAB/Simulink软件平台和dSPACE软硬件资源，建立了压电摩擦阻尼结构控制系统的仿真模型，采用快速控制原型技术对模型结构进行了地震反应振动台试验。通过振动台试验验证了地震作用下提出的压电摩擦阻尼器和以速度响应为输入的模糊控制方法调节阻尼器控制力的有效性。试验结果表明，提出的压电摩擦阻尼器能够根据结构的响应实时调整阻尼器的摩擦力，可以有效减小模型结构在地震作用下的位移反应和加速度反应。

Abstract

Based on the performance experiment of piezoelectric friction damper, a series of shake table tests were carried out using a piezoelectric friction damper under various earthquakes. The simulation model of the structure with piezoelectric friction damper was established by using MATLAB/Simulink software platform and software/hardware resources of dSPACE (digital Signal Processing and Control Engineering). The shake table experiments were implemented by using rapid control prototype technology. The seismic efficiencies of the designed piezoelectric friction damper and proposed velocity-input fuzzy control strategy were both evaluated. Experimental results indicate that the designed piezoelectric friction damper can adjust its damping force according to structure responses by proposed control method in real-time and effectively suppress the structural responses under earthquake excitations
