The numerical methods based on transfer matrix have been depicted,which is used to compute the natural frequencies and mode shapes of the transmission system.And the method to build the transfer matrix of each model has been discussed.In order to predigest the computation,the expanded transfer matrices have been used in the multi-rotor system.The boundary state vectors have been created to better and simply apply the boundary conditions.Finally,the process of creating a multi-rotor system has been depicted,and the key method to solve the matrix equation has also been discussed in the example of a simple transmission system. 扭转振动 传递矩阵法 多回转轴系统 扩展的传递矩阵 torsional vibration transfer matrix method multi-rotor system expanded transfer matrix U463.2 车辆传动国家重点实验室资助项目（51457080103BQ3103） 2005-01-01 2021-04-01 S2
