- 摘要：In this paper the optimized design of ultrasonic metal welding transducer has been done by using the finite element analysis method and the Screwing torque test. The converter part, boost part and horn part are all taken into account here. The p-wave propagation on the face and s-wave on the flange are approved primely. With the binding force changes, the mechanical Q value of transducer changes also followed. Therefore the amplitude of the output energy will be affected. Through the experiment the optimal design of the Screwing torque output were achieved. Metal Ultrasonic welding has its own special requirements. And the mechanical vibration frequency of the transducer is set as 20 kHz here. At last phase and frequency characteristics of the transducer were measured with Impedance Analyzer Test.
