【Abstract】 The effects of contact load and ratio of peak-peak amplitude of two-phase excitation voltage used for ultrasonic vibration on friction properties of ultrasonic drive were studied by using simulated tester of ultrasonic drive,by which the vibration ellipse of stator tooth of ultrasonic motor can be simulated.The results of research show that for each friction material there is the most optimum combination of contact load and excitation voltage under the condition of ultrasonic vibration driving.更多还原
