| 摘 要： | 将超声电动机定子和转子接触区定子表面一点的超声波振动分解成水平振动和垂直振动 ,并分析了两个方向振动对超声电动机驱动作用的影响。提出水平振动产生摩擦驱动力 ,垂直振动影响水平驱动的效果 ,将垂直方向超声波振动的作用等效为普通滑动试验中引入垂直滑动方向超声波振动的作用研究 ,揭示了垂直方向超声波振动是导致超声驱动动摩擦因数降低的原因

| Abstract: | Ultrasonic vibration of stator surface points at the contact region of stator and rotor in ultrasonic motor(USM) is resolved into horizontal and vertical vibration respectively. The effects of the two vibration on the drive properties of USM are analyzed.It is proposed that the horizontal vibration produces friction driving force and the vertical vibration affects this process.The action of vertical ultrasonic vibration is equivalent to that of ultrasonic vibration being perpendicular to sliding direction in common sliding test The reasons are that the vertical ultrasonic vibration results in decrease of sliding friction coefficient in ultrasonic drive |
