N2 - Particles enter the lubrication interface during operation of water lubricated stern bearings (WSB). This will affect the service performance. The mechanism of particle dynamics effect is not yet clear. This paper establishes novel fluid-structure coupling lubrication model of bearings with particle-dynamic effect. The relationship between liquid-film lubrication performance and particle-dynamic effect is clarified. The variation and influence rules of lubrication performance of bearings under different working conditions is specified. The interaction mechanism between particles and load-carrying performance is revealed. Theoretical analyses are consistent well with test, that verifies correctness and rationality of model and algorithm. Research is of great significance for the optimal design for such bearings under the service condition of heavy sediment.
