| 摘 要： | 利用压电材料的机电耦合特性，采用数值分析和实验相结合的方法研究了压电材料对支架的振动控制。利用Ｈａｍｉｌｔｏｎ原理，采用速度反馈，并考虑压电材料的机电耦合效应推导了振动主动控制有限元方程，分析了不同约束，不同压电片布置情况下支架的振动控制，实现了压电片的优化布置，同时用实验验证了数值分析的正确性。

| Abstract: | By using mechanical electro coupling character of piezoelectric material, active vibration control of supporter is studied by means of numerical analysis and experiment. Velocity feedback is adopted and taking into account mechanical electro coupling of piezoelectric material, finite element equation is derived by using Hamilton principle. Various boundary conditions and locations of piezoelectric patches are studied. The optimized location of piezoelectric patches is realized. The experimental result is provided. |
