Abstract:
对悬臂板、四边固支板及低频隔振系统开展了较为系统的压电振动控制研究，并在有限元环境，进行了压电控制电压的输入设计。数值计算结果表明，压电振动控制效果显著，验证了所提压电振动控制方法的有效性。本研究对于工程结构的压电振动控制具有指导意义，对于气浮振动控制等低频隔振系统开展压电主动控制，具有重要的实际工程应用价值。
The piezoelectric vibration control of cantilever plate, four-side fixed plate and low-frequency vibration isolation system was systematically studied in this paper, and the voltage input design of piezoelectric control was carried out using finite element method. The numerical results showed that the piezoelectric vibration control effect was significant, and the effectiveness of the proposed piezoelectric vibration control strategy was verified. This research has guiding significance for the piezoelectric vibration control of engineering structures, and has important practical engineering application value for the piezoelectric active vibration control of low-frequency vibration isolation systems such as air floating vibration control.
