| 摘 要： | 本文建立了滑动轴承的基于短轴承非线性油膜力模型,通过转速对轴承动力学特性的影响研究，得到了偏心率、最小油膜厚度、最大油膜压力、摩擦功耗、温升、临界轴颈质量、刚度系数、阻尼系数、二维和三维油膜压力的影响因素研究；在对三维油膜压力分析时发现存转速存在在一个临界值，当转速低于这个临界值时，转速对最大油膜压力影响较大，当转速高于这个临界值时，转速对最大油膜压力影响不大。

| Abstract: | Short-bearing oil film force model have been built in this paper. Rotor speed of bearing dynamics characteristics have been studied, which got the influence factor on eccentricity, the minimum film thickness, maximum film pressure, friction power, temperature, critical journal quality, stiffness coefficient, damping coefficient, 2D and 3D film pressure. There exists a critical rotor speed when analyze 3D film pressure. The maximum film pressure has great effect when rotor speed number is below the critical speed, and the maximum film pressure has little effect when rotor speed is higher than the critical speed. |
