- Abstract:
- The computation accuracy was often insufficient in the rod-type ultrasonic motor design because of the adopted continuous composite structure finite element model.In this paper,a method for modeling the rodtype ultrasonic motor vibrator based on bolt pretension was presented and the influence of bolt pretension and contact surface friction coefficients on modal frequency was analyzed.Experiments showed that,the deviation of motor working mode frequency is 0.05％,0.47％,0.64％ respectively through this finite element analysis method with consideration of bolted-joint nonlinear factors.Consequently,the calculation accuracy was good.It was shown that the finite element model based on bolted-joint nonlinear system was more conducive to motor performance design and estimation.
