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.
