摘要：

Water lubricated bearings are the key supporting parts in the propulsion systems of warships. The lubrication performances and the load carrying capacity characteristics of the bearings have significant effects on the hull structural vibration and vibro-borne noise of the whole system. However, as the lubrication mechanism is very complex, there is no effective design and calculation theories and methods for such bearings. Therefore, this project takes the new-type sandwich bearing as the research object. The fluid structure coupling lubrication models considering the influences of the double nonlinear effects, the misaligned load effects and other factors will be established in this proposal. The macro fluid solid interaction dynamic characteristics will be investigated. The influences of the multi coupling factors on the lubrication performance parameters will be analyzed. The macro-micro fluid solid structure synergistic lubrication mechanisms will be revealed. The research can promote the development of the lubrication theoretical system for the propulsion system in large ships.
