| In order to improve the problems of complex structure and small torsional component of mode conversion longitudinal torsional composite mode ultrasonic vibration system based on spiral grooves structure and inclined slots structure, a mode conversion longitudinal torsional composite mode ultrasonic vibration system based on new cylindrical holes composite horn is proposed in this paper. And the new cylindrical holes longitudinal torsional composite mode ultrasonic vibration system is simulated and analyzed by using finite element method and data analysis. The results show that the shear stress and rotation angle of the output end face of the system with the introduction of the new column hole composite horn have been greatly improved, which can effectively improve the conversion efficiency of longitudinal and torsional vibration. |
