摘要

本文建立了油膜轴承的模型，并对其进行了流体诱导不稳定性估计，为旋转机械系统的设计和诊断提供了理论依据。该模型由Modelica在原有的旋转机械库中实现。对采用滑动圆滑动轴承支承的Jeffcott转子系统进行了仿真。为了检查模型的行为，Campbell图和稳定性图是通过使用Modelica_LinearSystems2库来计算的。

Modelling of Oil Film Bearings

In this paper, we model the oil film bearings and estimate the fluid-induced instability for the design and the diagnosis of the rotating machinery system. The presented model is implemented in our original rotating machinery library by Modelica. An example of a Jeffcott rotor system supported by plain circular journal bearings is simulated. To check the behavior of the model, Campbell diagrams and stability maps are computed by using the Modelica_LinearSystems2 library.
