圆盘形和圆环形压膜轴承的气动力分析

Aerodynamic Analysis of Circular Plate-Shaped and Circular Ring-Shaped Squeeze Film Bearings

本文按照气体动力学理论,对圆盘形和圆环形压膜轴承的气动力作了详细的分析;给出了这两种轴承的压力分布的解析表达式,并用该方法修正了圆盘形压膜轴承的部分计算公式;还给出了这两种轴承的压力分布和承载能力的计算结果,可供设计者参考.

Aerodynamics of circular plate- and circular ring-shaped squeeze film bearings is analyzed in detail, yielding analytic expressions for the pressure distribution of these bearings. Several formulae for these bearings are modified using the developed method. The paper also gives numerical results of pressure distribution and load-bearing capacities of these bearings.
