| Abstract: | A nonlinear dynamic model of the stator of ultrasonic motor was established while considering the nonlinear constitutive relations of piezoelectric materials, Analytical and numerical methods were used to analyze the primary resonance of the stator of ultrasonic motor. The relationship between characteristics of the solution and parameters of the stator was given and the results make a foundation for further study of rotary traveling wave ultrasonic motor. |
