摘要/Abstract

摘要：

压电陶瓷开裂是影响超声波电动机使用寿命的关键因素。针对该故障类型,研究了一种模拟压电陶瓷开裂的行波型超声波电动机定子建模方法。建立无故障超声波电动机定子模型,经动力学分析后得到的定子质点运动轨迹验证了模型的合理性;改变裂纹长度以模拟陶瓷片的不同开裂程度,得到了孤极电压信号随裂纹尺寸的变化规律;对不同开裂程度故障电机的孤极电压进行了采样,分析结果表明仿真结果与实测数据具有较好的一致性。

关键词: 超声波电动机, 压电陶瓷开裂, 定子建模, 孤极电压

Abstract:

Piezoelectric ceramic cracking is the key factor to determine the service life of ultrasonic motor. A method used to simulate ceramic cracking in the stator of traveling wave ultrasonic motor was studied. The rationality of stator modeling was verified by the particle movement tracks via dynamic analysis. The fault degree of ceramic was simulated by different crack length, then the variation of monitor electrode voltage with crack dimension was analyzed. The monitor electrode voltage data of fault motor with ceramic crack was collected. The analysis shows that the simulation results are in good agreement with the actual measurement.

Key words: ultrasonic motor, piezoelectric ceramics cracking, stator modeling, monitor electrode voltage
