摘　　要：应用ADINA有限元方法,对无织构和有织构水润滑聚合物轴承的承载性能进行流固耦合有限元仿真分析,探讨不同内衬材料轴承在不同转速下的水膜压力分布及承载力变化状况,以及材料弹性模量、转速、水膜压力对凹坑表面织构变形的影响规律。仿真结果表明:内衬材料弹性模量对凹坑变形及水膜压力有重要影响,在相同条件下,弹性模量越大,水膜压力及承载力也越大,因此内衬材料应选弹性模量较大的聚合物材料;在相同条件下,有织构轴承的水膜压力和承载力均高于无织构轴承;轴承发散区的织构布置初始角对轴承承载力分布状况有一定影响,随初始角的增大轴承承载力呈现先升高后降低的变化趋势。The fluid-structure interaction simulation analysis of the load-carrying property of two kinds of water lubricated polymer bearings with no-textured and textured surfaces was carried out with ADINA finite element method.The variation of water film pressure distribution and carrying capacity of the bearings with different lining materials under different rotating speeds was explored,and the influence of the elastic modulus of the polymer materials,rotating speed and water film pressure on the deformation of pit texture was analyzed.The simulation results show that the elastic modulus of the material has important impact on the pit deformation and the water film pressure.Under the same conditions,the greater the elastic modulus is,the greater the water film pressure and bearing capacity are.Therefore,the polymer material with higher elastic modulus should be selected as the lining material of water lubricated bearing.The water film pressure and carrying capacity of the textured bearing are higher than that of the no-textured bearing under the same conditions.The initial angle of texture arrangement in the divergent zone of the bearing has a certain effect on the carrying capacity distribution of the bearing,with the increase of the initial angle,the bearing capacity of the bearing is first increased and then decreased.
