【摘要】 采用内缘固定的B13振动模态,设计出一种新型盘形行波型超声波电动机。利用Ansys动力学分析方法仿真定子的振动情况。考虑了定子外径、定子齿分布圆位置和齿高等结构因素,计算了超声波电动机的定子齿振幅、共振频率、振动速度和接触面质点运动轨迹等参数的变化情况,并设计出超声波电动机结构样机。结果表明,该超声波电动机的结构简单、质量轻、转速较高,并具有一定的转矩。更多还原

【Abstract】 Using B13 vibrating mode and fixing interior edge of stator,a new disc type of traveling wave ultrasonic motor(TWUSM) was designed.ANSYS dynamic analysis method was introduced to simulate the vibrating station of stator.Structure factors like exterior diameter of stator,distribution circle location of stator teeth and the height of tooth were considered.The variation of related parameters were calculated,such as amplitude of stator teeth,resonate frequency,vibrating speed,motion locus of contact particles,etc.Then,a prototype of TWUSM was fabricated.The results showed that this kind of TWUSM has simple structure,light weight and high speed,and a certain torque as well.更多还原
