摘　　要：以悬臂板压电结构为对象,分析其固有频率和阻尼,并探究压电片电压与振幅特性的关系。运用COMSOL进行力场、电场的复合结构仿真,得出了该结构的模态特性,得到了悬臂板压电结构在施加电压时产生振动方向的挠度变化及在振动时压电片的电压变化,为振动主动控制提供参考。Taking the cantilever piezoelectric structure as the object,its natural frequency and damping are analyzed,and the relationship between piezoelectric voltage and amplitude characteristics is explored.COMSOL is used to simulate the composite structure of force field and electric field,and the modal characteristics of the structure are obtained.The deflection change in the vibration direction of the cantilever piezoelectric structure when voltage is applied and the voltage change of the piezoelectric plate when vibration are obtained,which provides a reference for active vibration control.
