摘　　要：从理论上推导了在某一模态下超声波电动机振子的模态参数之间的关系,利用ANSYS软件对超声波电动机压电振子进行数值模拟分析,实现了基于ANSYS的压电振子各动力学参数的提取,从而将复杂的超声波电动机振子模型简化为单自由度的弹簧-质量系统,经与理论计算值对比,结果表明该方法对于获得超声波电动机动力学参数行之有效。The relationship of modal parameters was introduced and proved theoretically.Through modal and harmonic analysis of piezoelectric ultrasonic vibrator based on ANSYS,the modal parameters of rectangular piezoelectric resonator were extracted,by which the vibrator model was simplified as the spring single-degree-of-freedom system.Results show it is a effective way to obtain the dynamic parameters by comparing with the theoretic results.
