摘　　要：通过有限元分析的方法,利用ANSYS对以压电元件的逆压电效应为驱动力的平衡装置中的压电元件进行瞬态分析,发现在周期正弦信号的驱动下,压电元件有明显的收缩和扩张现象.通过对压电振子表面上的节点作位移分析,在同一个极角坐标下,各节点的位移轨迹基本相同,各节点的位移曲线都近似于正弦,在同一时刻同一极角坐标下的各节点的位移量近似相等.Through the nonlinear transient dynamic analysis of the piezoelectricity component in the on- line-balancing device which used piezoelectricity effect principle by ANSYS, the obvious contraction and the expansion phenomenon were observed under the cyclical sine actuation in the piezoelectricity component. The displacement on the piezoelectric vibrator surface was analyzed by ANSYS with that the various nodes have the basic same displacement path under a same polar angle coordinate. The displacement curve is an approximate sine function, and the displacement quantity is approximately equal under the same time and polar angle coordinates.
