摘　　要：综合考虑水润滑橡胶轴承不同开槽结构的润滑特性,设计出一种具有混合槽结构的橡胶轴承。采用有限元法建立了水润滑橡胶轴承双向流固耦合模型,研究不同沟槽结构对橡胶衬层变形、水膜压应力分布以及流场速度分布的影响,结果表明,混合槽结构综合了U形、V形和T形槽结构的各方面优势,能够改善水润滑橡胶轴承的流体润滑特性。The lubrication characteristics of water-lubricated rubber bearings with different groove structures are considered comprehensively,and the rubber bearings with mixed groove structure are designed. The bidirectional flow-solid coupling model for the bearings is built by using finite element method,and the effects of different groove structures on deformation of rubber lining,compressive pressure distribution of water film and velocity distribution of flow field are studied. The results show that the mixed groove structure integrates advantages of U-shaped,V-shaped and T-shaped groove structures,and the elastohydrodynamic lubrication characteristics of the bearings are improved.
