| Abstract: | This paper describes a new type of ultrasonic linear motor using anisotropic materials (CFRP) as its vibration body,analyzes its actuating mechanism and established the dynamic equation of the vibration body.The two resonant frequencies of the motor are calculated.They correspond to the bi directional motion of the motor.The experiments on the driving force and speed of the motor are also carried out.The results show that the greatest driving force is 0.5 N and the speed varies from 0 mm/s to 8 mm/s with the change of the driving voltage.The bi directional motion of the motor can be implemented by the switchover of the two resonant frequencies. |
