Based on the influence of specific working conditions (speed,eccentricity,etc.) on the lubrication characteristics of water lubricated sandwich bearings,the materials of double lining water lubricated bearing were studied.The one-way and two-way fluid-structure interaction dynamic models were established,and their effects on the bearing were compared.The influence laws of elastic modulus and Poisson’s ratio on static performance parameters such as bearing load,pressure and deformation were proved.The change mechanism of static performance of double lining water lubricated bearing under fluid-structure interaction was revealed.The research indicates that the static performance of the solid domain of water lubricated bearings changes significantly with the change of liner material parameter.The performance of the fluid domain does not change significantly.The results enrich the selection range of double liner water lubricated bearing materials and provide a theoretical basis for the selection of bearing materials.
