| Abstract: | The transmitting model of ultrasonic vibration in ultrasonic transducer and capillary is given in this paper by utilizing the propagating mechanism of ultrasonic wave in elastic body. The ultrasonic vibration displacement and velocity of high frequency are measured with the laser doppler vibration PSV-300-F(1.5MHz),then the conclusion in theory is proven. Welding characteristics of welding tool with ultrasonic longitudinal complex transverse vibration system are studied. It shows that longitudinal complex transverse vibration system is a model of high-efficient energy transmission. And we draw some conclusions that have important instructional significance to optimize ultrasonic vibration system, improve the energy transmission efficiency and study the character of energy transmission of the ultrasonic vibration system. |
