Study on Ultrasonic Micromateriel Transmission System

Abstract:

Article Preview

A new type ultrasonic materiel transmission system is proposed in this study. In this new design, bending vibration traveling wave is generated in an elastic pipe by using two uniform sandwich type longitudinal vibration transducers. Thus, elliptical trajectory motions can be formed at particles on the pipe wall, which can drive the materiel by frictional force. The adopting of sandwich transducer in this device can gain large vibration amplitude and improve the electromechanical coupling efficiency. The structure and working principle of the proposed design are introduced. The transducer and the pipe are designed and analyzed by using FEM method. The longitudinal vibration mode of the transducer and the bending vibration mode of the pipe are analyzed, and the resonant frequencies of these two modes are tuned to be close. A prototype system is fabricated and measured.
