建立水润滑橡胶合金轴承3D流固耦合模型，应用流体计算分析软件对轴承运行过程中的内部流场进行分析。分析结果表明，转速和偏心率是影响水膜压力分布、水膜流速分布和承载能力的重要因素，采用较大的转速有助于流体动压形成，增大偏心率将会增大轴承系统中水的动压，从而增大水膜压力和承载能力。橡胶层的变形和应力分析表明，橡胶层主要承载面的变形量和应力随着转速和偏心率的增加而变大，在橡胶衬层与轴套黏接面处有最大应力，设计中应该充分考虑橡胶衬层的物理性能及其与铜套黏接面的力学性能。

3D fluid?structure coupling model of water lubrication rubber alloy bearing was established.Fluid calculation software was applied for the analysis of internal flow field in the running bearing.The analysis results show that speed and eccentricity are the important factors influencing the water film pressure distribution,water film velocity distribution and bearing capacity.The larger speed helps to form hydrodynamic pressure.The increase of eccentricity will increase dynamic water pressure,and increase water film pressure and bearing capacity.The analysis of deformation and stress of rubber layer shows that the deformation and stress of main bearing surface of rubber layer are increased with increased speed and eccen?tricity.Maximum stress is located in the rubber lining and shaft sleeve adhesive surface.The physical properties of the rub?ber lining and its mechanics performance on the shaft sleeve adhesive surface should be fully considered in the design.
