摘要

摘要: 提出了一种新型纵扭复合超声振动系统的设计方法，并应用有限元软件对其正确性进行仿真验证。利用矩阵传输理论得出了指数过渡变幅杆的纵扭共振频率方程及放大倍数，其间利用MATLAB软件对此频率方程进行了求解；然后通过对圆棒中有纵扭复合振动时的应力状况进行分析，得出了一种新型的纵扭同频激励方式。按此法设计纵扭复合超声振动系统，并应用有限元软件ANSYS进行模态分析与瞬态动力学分析。结果表明：有限元分析与理论计算结果吻合较好。

Abstract: A new design method for longitudinal-torsional composite of the ultrasonic vibration system was put forward and the finite element software ANSYS was used to validate this method. Firstly, based on the transfer matrix theory, the resonance frequency equations and the vibration velocity amplification coefficient for the longitudinal-torsional composite vibration of the horn were derived. Meanwhile, the resonance frequency equations were solved by using the software of MATLAB. Then, stress states of the rod when the longitudinal and torsional vibration travels in the rod were studied, and a new incentive mechanism for longitudinal and torsional vibration mode was put forward. Finally, a new type of longitudinal-torsional composite of the ultrasonic vibration system was designed and its dynamic characteristics were calculated using ANSYS. Results show that the calculated resonant frequencies agree well with the designed frequencies, and the longitudinal vibration frequency and torsional vibration frequency are almost equal to each other.
