摘　　要：运用四端网络法设计了一种新型的圆锥悬链线形复合变幅杆,对变幅杆进行了理论分析,得出频率方程和放大倍数的表达式,采用MATLAB解算出变幅杆的谐振长度、放大倍数和节点位置。并利用ANSYS软件对其进行模态分析和谐响应分析,结果表明有限元分析结果与理论设计基本一致,符合变幅杆设计要求。利用该方法可以将其他任意形状的变幅杆进行组合得出新型变幅杆,为变幅杆的优化设计提供了借鉴,有一定的实用价值。A new type of conical catenary composite horn is designed using the four-terminal network method. The horn is analyzed theoretically, and the frequency equation and the expression of the magnification are obtained. MATLAB is used to solve the resonance length, magnification and node position of horn. ANSYS software is used to perform modal analysis and harmonious response analysis. The results show that the finite element analysis results are basically consistent with the theoretical design and meet the design requirements of the horn. Using this method, other horns of any shape can be combined to obtain a new horn, which provides a reference for the optimal design of the horn, and has certain practical value.
