In the meantime, the difference between a direct integration method and a modality superposition method in the nonlinear solution of large sized shaftings was also investigated. It can be shown that the use of a nonlinear method for solving the kinetics response of a higher dimensional rotor bearing system is both essential and feasible. With regard to the nonlinear kinetics problems of a rotor system the direct integration method is more effective than the modality superposition method. steam turbine, rotor, dynamics, nonlinearity

国内外先后采用非线性油膜力的数值积分方法对转子轴承系统的非线性动力学行为进行了一定研究，但主要集中在简单转子—轴承系统的研究上，在分析上主要采用的是简单离散方法，转子多被简化为刚性转子和Jeffcott转子模型，只能对简单转子—轴承系统的非线性动力学行为进行定性的分析，而对于象汽轮机组轴系这样的高
