Abstract

Traditional power ultrasonic vibration systems can process one object at one time and only have one output. A directional converter of longitudinal vibration with multiple outputs composed of an input rod, a hemispherical vibrator, and three output rods is presented. The frequency equation used in the design is derived with free edges at the input and output ends of the converter, as well as the continuity of displacements, forces, and angles of rotation at each component junction. The resonant frequencies of three fabricated converters designed using the proposed method are in good agreement with those from the finite element method and also with tested values. With the input end of the converter joined with a piezoelectric transducer with a resonant frequency of 19.8 kHz, the longitudinal vibration modes and displacement amplitudes of the output ends of the three converters at their resonant frequencies are tested. The results show that longitudinal vibration can be transferred from the input end to the multi-output ends through the converter. Furthermore, there exists a linear relationship between the excitation voltage and the displacements of each output of the converter.

一种单输入多输出的纵向振动定向变换器

传统的功率超声振动系统一次只能处理一个物体，只有一个输出。提出了一种由一个输入杆、一个半球形振子和三个输出杆组成的多输出纵向振动定向变换器。设计中使用的频率方程是在转换器的输入端和输出端具有自由边，以及每个组件连接处的位移，力和旋转角度的连续性的情况下导出的。用该方法设计的三种加工变换器的谐振频率与有限元计算结果和试验值吻合较好。将转换器的输入端与谐振频率为19.8 kHz的压电换能器连接，测试了三个转换器在谐振频率下的纵向振动模态和位移幅值。结果表明，纵向振动可以通过变换器从输入端传递到多输出端。此外，励磁电压与变换器各输出的位移之间存在线性关系。
