摘要
Under the condition of ultrasonic vibration, the friction properties of several materials were studied experimentally; and the mechedsm of friction force reduction on the resonance was also analyzed. It is found that tungsten carbide and 45# steel are an ideal friction couple for ultrasonic motor.
