摘　　要：鉴于高能聚焦超声波清洗机声学系统的复杂性,利用传统的解析法对其进行动态分析有一定的困难,利用有限元方法对其进行分析。借助有限元分析软件ANSYS对便携式超声波清洗机的声学系统进行了模态分析及谐响应分析,从理论上验证了声学系统的动态特性。The acoustic system shape of high-intensity focus ultrasonic cleaning machine is very complicated, and it is very difficult to analyze with traditional analytical method. It was analyzed with the finite-element method. The model analysis and harmonic response analysis were carried out, and the dynamic characteristics of the acoustic system was proved in theory.
