摘要
本文考虑涡动比、瓦块惯性、支点摩擦以及瓦背气膜刚性和阻尼的影响,对弹性支承可倾瓦气体径向轴承的动态性能进行了分析。文中介绍了瓦背气膜动特性的计算方法。此外,还分析计算了用该种轴承支承的转子系统的稳定性。
In this paper,the dynamic behaviors of an elastically supported tilting pad gas journal bearing are analysed with consideration of fhe influnces of whirl ratio,pad inertia,pivot friction as well as gas film stiffness and damping effects on the back of the pads.A method for calculating the dynamic characteristics of the gas film on the back of the pad is introduced.The stability of a rotor systen supported on such bearings is also analysed.
