本文利用模态综合法和谐波平衡法提出了一种有效的转子系统非线性振动分析方法。在该方法中，系统被分为一些组件，并导出每个组件的每个频率的微分方程。然后，利用分量模态综合方法获得整个系统的运动方程。采用谐波平衡法对转子系统进行动态分析。该方法的显着特点是非线性恢复力项用模态坐标以方便的形式表示。因此，可以减少运动模态方程的阶数和计算时间。数值算例表明本文提出的分析方法对于转子系统非线性振动分析是有效的。
In this paper, an effective method for the nonlinear vibration analysis of rotor system is proposed by using the Component Mode Synthesis method and the Harmonic Balance Method. In that method, the system is divided into some components and the differential equations for each frequency for every components are derived. The equation of motion for the whole system, then, is obtained by using the Component Mode Synthesis method. The dynamic analysis of rotor system is carried out by using the Harmonic Balance Method. The distinguished feature of the proposed method is that the nonlinear restoring force term is represented by using modal coordinates in the convenient form. The order of the modal equation of motion and calculation time, therefore, can be reduced. In the numerical example, it is shown that the analysis method proposed in this paper is effective for the nonlinear vibration analysis of rotor system.
