低控制电压的杂交阻尼

Abstract

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.

Key words: vibration suppression, hybrid damping, hybrid control, intelligent control
