建立了用有限元子结构模态综合法进行轴向预紧端齿连接转子动力特性分析的公式系统。重点阐述如何考虑端齿及变轴力的影响，如何获得变轴力端齿梁元的性质矩阵和建立变轴力端齿梁元及系统的运动方程。
The formula system for analyzing the dynamic characteristics of rotor with axial pretensioned end tooth is established by using modal synthesis method of finite element substructure. This paper focuses on how to consider the influence of the end tooth and the variable axial force, how to obtain the property matrix of the variable tooth end beam and the equations of motion of the system.
