摘要:
3自由度超声电机利用圆柱定子的3种同频共振模态(2个正交的弯曲摇摆振动和1个纵向振动),两两分别叠加、合成,通过摩擦驱动球转子分别绕3个轴旋转.根据这一原理可将该电机改装成多自由度直线电机.通过有限元方法设计定子的结构和模态,利用阻抗测试方法测得的定子共振频率、模态与设计相符,同时测量了球转子绕3个轴的转速特性.为了提高3自由度圆柱超声电机的定转子传动效率,对圆柱型定子锥形端面作了进一步优化设计.
Abstract:
A three-degree of freedom(DOF)ultrasonic motor that uses a cylinder stator is developed. The three-DOF ultrasonic motor can be constructed when three natural frequencies of a stator are made to correspond. When two of these natural vibrations, two bending modes perpendicular to each other and a longitudinal mode, a spherical rotor in contact with the stator head rotates around three perpendicular axes. The operational principle can realize multi-DOF linear motion. The structure of three-DOF ultrasonic motor is designed using finite element analysis. By using the impedance-measurement, the natural frequencies and natural modes of vibration agree well with those calculated. In addition to the confirmation of three-DOF motion, the basic characteristics of the three-DOF motion, the rotational speed of the spherical rotor around three perpendicular axes were measured. To increase conversion efficiency from stator vibration to mechanical output of the three-DOF motor, the optimized taper angle of the contact surface between cylinder stator and spherical rotor is constructed.
