摘要
基于压电元件的被动控制技术正得到越来越多的重视。该文以悬臂梁为受控结构,深入研究和探讨了RLC电路在多模态振动中控制的应用。具体分析了压电片的最佳粘贴位置和模拟电感的实现等问题,最后给出了串、并联形式的RLC电路在悬臂梁减振应用中的实验结果。
At present, more and more attention is paid to the passive control based on piezoelectric ceramic. In this paper, the multiple mode passive control of cantilever beam with RLC circuit based on piezoelectric is discussed in detail. Besides, the optimized position of piezoelectric transducer and the implementation of simulated inductor are also showed. At last, a series RLC circuit and a parallel RLC circuit are designed, and some experimental results are given.
