本文提出了一种计算大型转子—轴承—基础系统动力响应的新方法。该方法的主要特点是既适用于线性支撑的情况。也适用于非线性支撑的情况,轴承的动态特性参数不参加为缩减系统的自由度而进行的模态参数计算,并且方法具有明确的物理意义。
This paper presents a new method for calculating the dynamic response of a large rotor-bearing-foundation system. The main feature of this method is that it is suitable for linear support. It also applies to the case of nonlinear support. The dynamic parameters of the bearing do not participate in modal parameter calculation to reduce the degree of freedom of the system, and the method has clear physical meaning.
