摘　　要：基于环形振子面内弯曲振动模态,提出将行波直线超声电机的长环型振子用于小块体物料的振动输送技术,研制出一种具有宽输送面的不对称压电输送振子,并对该振子进行了振动测试和实物输送实验研究。Based on the bending modes generated in the plane of the vibrator, a novel piezoelectric vibrator of the ring type, which used for conveying millimeter size solid objects, is presented. The nonsymmetrical structure of ring type vibrator is manufactured, which possesses wide conveying surface. The vibration modes and performance of the conveying prototype are experimentally studied.
