| 摘 要： | 提出一种用多层压电片和约束阻尼层在低控制电压下进行结构振动的杂交阻尼控制方式。基于各种材料的本构关系，导出了多层压电片作用在梁结构上的力和所施加的电压以及结构的运动之间的耦合关系和系统的控制微分方程。讨论了多层压电片附加位置的优化。仿真计算表明，这种杂交阻尼控制方式有着良好的振动抑制效果和较低的控制电压。

| Abstract: | An active and passive hybrid damping control manner with lower voltage is proposed through both multiple piezoelectric patches and constrained damping layer for suppressing structural vibration. The formula of actuating force produced by multiple piezoelectric patches and the control equations of multi layer beam are derived based on the constitutive relations of different materials. The optimal placement of multiple piezoelectric patches is discussed. The simulation indicates that the proposed hybrid damping control manner is a satisfactory way to suppress the structural vibration and lower the control voltage. |
