摘要

利用数值分析方法，建立带封油边结构的滑动轴承单向流固耦合模型，分析了不同转速下的滑动轴承润滑性能及轴瓦变形规律。结果表明，带封油边滑动轴承的油膜承载力、压力峰值、温度、壁面切应力均高于无封油边滑动轴承，气相体积分数、摩擦因数和出口端泄流量则均小于无封油边滑动轴承，且油膜承载力、压力峰值和温度等均随着转速的增加而增大；滑动轴承轴瓦变形主要受温度的影响，带封油边轴瓦变形大于无封油边轴瓦变形，且轴瓦变形均随着转速的增加而增大。

Abstract

The numerical analysis method is used to establish the one-way fluid structure coupling model of sliding bearing with oil seal edge structure， and the sliding bearing lubrication performance and bearing pad deformation are analyzed at different speeds. The results show that the oil film bearing capacity， pressure peak value， temperature and wall shear stress of the sealed oil edge sliding bearing are higher than unsealed oil seal edge sliding bearing， gas phase volume fraction， friction factor and outlet leakage flow are all smaller than oil unsealed edge sliding bearings， and the oil film bearing capacity， pressure peak and temperature are increased with the increase of rotating speed. The deformation of sliding bearing bush is mainly affected by temperature， the deformation of bearing pad with oil sealing edge is larger than without oil sealing edge， and the deformation of bearing bush are increased with the increase of rotating speed.
