分析了超声振动的减摩机理和振型、振幅等因素对减摩作用的影响，认为超声振动使摩擦面间的实际接触面积显著减小是导致摩擦力显著下降的主要原因。设计制造的直线式超声振动减摩试验机构具有一定的减摩作用，当信号源驱动电压为１６０Ｖ时，超声振动可使摩擦系数降低约６３％。
The mechanism of the anti-friction of ultrasonic vibration and the influence of vibration mode and amplitude on the anti-friction effect are analyzed. It is considered that the actual contact area between the frictional surfaces is significantly reduced by the ultrasonic vibration, which is the main reason for the significant decrease of the friction force. Design and manufacture of linear ultrasonic vibration anti-friction test mechanism has a certain anti-friction effect, when the signal source drive voltage of 160V, the ultrasonic vibration can reduce the friction coefficient of about 63%.
