摘要
考虑了摩擦层剪切变形,对行波型超声波电机定转子接触区域内的粘滑分布特性进行研究。首先假设超声波电机定转子接触区域内完全为粘滞分布的情况下,求得接触区域内摩擦材料的切向应力;再与滑动摩擦应力进行比较,从而确定接触区域内粘滑分布情况及其分布规律,并根据所获得的粘滑分布计算电机运行性能。最后,对理论分析的结果进行实验验证,实验结果与理论分析结果相吻合,验证了理论分析的正确性,为超声波电机的设计与分析提供了理论依据。
The objective of this paper is to study the stick-slip distribution of the contact area between stator and rotor in traveling wave ultrasonic motor taking into account the shearing deformation of the frictional layer.Firstly,the tangential stress is calculated assuming that there exists only stick distribution in the contact area.Secondly,the tangential stress is compared with the sliding frictional stress.The stick-slip distribution as well as the performance of the motor is determined then.Finally,the analyzed result is verified by the experiment,and good agreement is obtained.The result is identified as being useful in designing and analyzing the ultrasonic motor.
