According to the impedance match principle, dynamics model of the whole machine composed of rotor bearing foundation is built. 根据阻抗匹配原理,建立了由转子轴承基础(RBF)所组成的整机动力学模型。
On the assumption of short bearings, consideration the vertical deformation of the foundation, the coupled nonlinear dynamic model of the rotor bearing foundation system is formulated in this paper. 在无限短转子-轴承的基础上,考虑基础在垂直方向的变形,通过分析油膜力,建立了转子-轴承-基础非线性动力学模型。
