摘　　要：研究超声物料输送装置的压电振子,其工作模态为面内弯曲振动。通过动态设计找出两个频率相等波长相差45°的弯曲振型,实现跑道形振子面内弯曲行波,使上下横梁产生微观运动,通过物料与振子间的摩擦力完成物料输送。The piezoelectric vibrator of ultrasonic feeding device was studied, which operation modes are in-plane bending, Two bending vibrations with same frequency and wavelength difference of 45were found out by dynamic design to realize in-plane bending traveling wave of the vibrator. The micro elliptic motion was produced between up and down beams.The material transport was achieved through the friction between the material and the vibrator.
