| Abstract: | Considering the slow crawling problem of bimodal ultrasonic motor(BUSM),a novel actuation mode of BUSM combined with wavelet drive and pretension angle control through the further study of BUSM drive mechanism was presented,which demonstrated its advantages in solving the slow crawling problem.The theory analysis and test results showed that the guide wave in wavelet drive benefited the conversion from static friction coefficient to dynamic friction coefficient of stage and made the stage acquired initial m... |
