文中采用简化传递矩阵法计算带刚性支承、球铰的转子的临界转速和带定心弹性支承的挤压油膜阻尼器的双转子系统的不平衡响应。简化传递矩阵法求解范围广,计算机程序简单,规律性强。特别适于带刚性支承、球铰和中介轴承的转子系统的计算。计算方法是将多转子系统分割成几个单转子系统,再按边界条件耦合起来建立线性方程组求解。对此方法进行了理论和实验的检验,均有很好的一致性。由于带定心弹性支承的挤压
In this paper, the simplified transfer matrix method is used to calculate the critical speed of a rotor with a rigid bearing and a spherical hinge, and the unbalance response of a two-rotor system with a squeezed oil damper with a centering elastic support. Simplify the transfer matrix method to solve a wide range of computer programs is simple, regular and strong. Especially suitable for the calculation of rotor systems with rigid bearings, ball joints and intermediate bearings. The calculation method is to divide the multi-rotor system into several single-rotor systems, and then coupled to establish a linear equation solution according to the boundary conditions. This method has been tested in theory and experiment, all have very good consistency. Due to the centering of elastic support extrusion
