摘要
为了研究矩形沟槽结构参数对水润滑轴承弹流润滑性能的影响,建立水润滑轴承流固耦合(FSI)分析模型,采用有限元法,通过比对轴承周向水膜压力、最大水膜压力、摩擦系数、承载力、偏位角和轴承最大径向变形等参数,阐述了矩形沟槽结构参数对轴承润滑性能的变化规律。结果表明,沟槽宽度或深度越大的轴承,其承载性能越差。通过合理调整沟槽的宽深比,可以有效地改善轴承的润滑状态。在相同流水槽总断面积下,沟槽宽深比过大或过小均不是轴承弹流润滑的最好状态,沟槽宽度对轴承承载性能的影响要高于沟槽深度对轴承的影响。
In order to study the influence of rectangular groove structure parameters on the elastohydrodynamic lubrication performance of water-lubricated bearings,a fluid-structure interaction(FSI)analysis model is established.By using finite element method,parameters such as the circumferential water film pressure,maximum water film pressure,friction coefficient,bearing capacity,deflection Angle and maximum radial deformation of bearings are compared.The variation rule of rectangular groove structure parameters on bearing lubrication performance is described.The results show that the bearing with greater groove width or depth has worse bearing performance.By reasonably adjusting the width to depth ratio of the groove,the lubrication state of the bearing can be effectively improved.The same flow groove total cross-sectional area ratio,groove width to depth ratio is too large or too small is not the best state of bearing elastomeric lubrication.The impact of groove width on the bearing load performance is higher than the impact of groove depth on the bearing.
