【Abstract】 Research on the dynamic characteristics of a new type coupling vibrator o{ PUM by finite element method is presented in this paper. The calculating results are consistent with experimental results. Furthermore, we have studied influence on frequency and mode shape of size and shape of the component parts of the coupling vibrator to find their best combination.更多还原
