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.
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。

Piezoelectric or stored charge effects: the creation of charge unbalances (and thus current flow or voltage shift) due to mechanical stress.
压电或储存电荷效应：由于机械应力产生的电荷不平衡(从而产生了电流或电压偏置)。

Piezoelectric pieces are added to vibration system, they vibrate with system together and generate induced voltage.
