夹心式超声波换能器研究及设计

Research and Design of Sandwich Ultrasonic Transducer

针对工业生产中存在的结垢问题,基于超声波除垢的方法技术,对用于除垢的压电陶瓷换能器和变幅器进行研究,设计了一种夹心式压电陶瓷换能器,将变幅器输出端设计为矩形,并对其进行ANSYS仿真和模态分析。结果表明,仿真结果与设计目标误差小于3%,工作过程中最大应力和输出振幅满足实际使用需求,为超声波除垢工作在复杂环境的固定和能量传输提供了一种新的设计方法。

To resolve the problem of scaling existed in industrial production,based on the method and technology of ultrasonic scaling removal,this paper designs piezoelectric ceramic transducer and amplitude converter used for scaling removal.A sandwich piezoelectric ceramic transducer is designed,and the output end of the amplitude converter is designed as a rectangle.ANSYS simulation and modal analysis are carried out.The results show that the error between the simulation results and the design target is less than 3%,and the maximum stress and output amplitude in the working process meet the practical requirements,which provides a new design method for the fixing and energy transmission of ultrasonic descaling work in complex environment.
