超声波液体处理中声场分布与换能器特性研究
Research of Acoustic Field Distribution and Transducer Characteristics in Ultrasonic Liquid Treatment
摘要
Abstract
To improve the control accuracy of the transducer,the load liquid acoustic field distribution and the vibration performance of the ultrasonic transducer in ultrasonic liquid treatment are studied from theoretical and experimental aspects.The finite element analysis software is used to simulate the designed ultrasonic transducer and vibration system,and the parameters such as resonant frequency of the transducer are studied by modal analysis through COMSOL,and the actual liquid treatment finite element model is established and the pressure acoustic analysis is performed on the ultrasonic vibration system to obtain the parameters such as sound pressure and sound intensity in the load liquid.The real-time control of ultrasonic vibration system frequency is realized based on the integrated chip,and the experiment shows that the actual resonant frequency of the transducer has only 0.12%error with the simulated resonant frequency,the actual output amplitude error is less than 0.5 μm,and the sound intensity error is less than 0.1 W/cm2.The simulation model has a small error with the actual one,which can accurately predict the operating state of the transducer and help guide the design of the trans-ducer and the analysis of the liquid sound field.关键词
