摘　　要：根据细胞微切割实验对超声振动切割系统的要求,对夹心式超声换能器和超声变幅杆组成的振动系统进行了设计,超声换能器采用夹心式压电换能器,变幅杆是一种将等截面圆柱形阶梯变幅杆的一端替换成圆锥形变幅杆构成的新型复合圆锥阶梯形变幅杆,设计了超声换能器和变幅杆的基本结构,并给出其制造尺寸。In view of Ultrasonic Vibration Cell Cutting System is studied in order to meet the requirements of Cell Cutting experiment System, the sandwich piezoelectric ultrasonic transducers and ultrasonic amplitude transformer are studied. Ultrasonic transducers is the sandwich piezoelectric, and a new compound cone step type amplitude transformer is firstly presented and carried out. The basic theoretical parameters of the compound cone step type amplitude transformer is presented, the size of the ultrasonic amplitude transformer is offered, the ultrasonic amplitude transformers is designed and manufactured.
