摘　　要：推导了不同形状函数变幅杆的四端网络表达式,完成了超声珩齿振动系统的结构设计。利用ANSYS软件进行了动力学分析,验证了设计的变幅杆可满足系统谐振的要求。中空变幅杆可有效地提高变幅杆的放大比,为大孔径齿轮的高效珩齿的变幅杆设计提供了一种新方法。This paper derived four-terminal network expressions of horns with different section shape function, based on the transfer matrix theory and proved that the designed horn can meet the requirements of resonant vibration system by the finite element analysis with ANSYS software. The amplification factor of a conical horn with a hole can be improved efficiently. Therefore,the horn with bigger diameter hole is a new design method of the gear with a bigger central hole in ultrasonic gear honing.
