Study on lubrication performance of radial sliding bearing with different contact angles based on FLUENT

文章以某型舰径向滑动轴承为模型,针对接触角结构参数变化对轴承润滑性能的影响,采用UG软件建立了轴承不同接触角参数下油膜模型,采用ICEM划分了油膜四面体网格,通过FLUENT仿真软件分析了轴承稳定工况不同接触角大小与轴承油膜压力分布、承载力关系和气穴程度的关系,得出了轴承在接触角为116°附近时轴承承载力最大,其结论可为大型舰径向滑动轴承的设计、试验和制造提供理论支撑。

In this paper,a type of ship radial bearing is considered as a model,according to the influence of the change of microstructure parameters on bearing lubrication performance under different contact angles,the oil film model is established by using software,and the ICEM is used to divide the oil film tetrahedral mesh,the relationship between the contact angle and bearing oil pressure distribution,bearing capacity and the degree of cavitation is analyzed by FLUENT simulation software.The results show that the bearing capacity is the largest when the contact angle is about 116°,which can provide the theoretical support for the design,test and manufacture of the large ship radial plain bearing.
