中文摘要	针对目前圆柱型超声电机定、转子间相对滑动较大,导致电机效率低下等问题,推导了定子端面驱动质点的运动轨迹方程,并利用MATLAB软件对驱动质点的运动轨迹进行仿真分析;采用有限元法对本研究提出的柔性接触结构进行接触变形分析;对定子进行模态和谐响应分析。结果表明:定子端面驱动质点的运动轨迹为一椭圆,椭圆面与定子端面呈一定夹角;本研究提出的柔性接触结构能有效减少定、转子间的相对滑动。; There exists a great slippage between the stator and the rotor of a cylindrical ultrasonic motor,which will lead to a low motor efficiency.A motion equation of a driving point on the top surface of the stator was deduced.The motions of the driving points on the top surface of the stator were simulated by using MATLAB software.The deformation on the flexible structure of contact area presented in this paper was analyzed using FEM.The modal and harmonic responses of the cylindrical stator were also analyzed.The calculated results indicate that the motion locus of the driving point on the top surface of the stator is an elliptical curve,and there is an angle between the elliptical motion surface and the top surface of the stator.The flexible structure of contact area can reduce the relative slippage between the stator and the rotor effectively.
