Abstract： This paper investigated the vibration-oil film coupling mechanism in axial piston pumps through an integrated dynamics model combining pump component dynamics with slipper/swashplate and valve plate/cylinder block lubrication models. The model was solved using a combined explicit-implicit approach with control volume method.Experimental validation confirmed the model effectivenes in predicting vibration characteristics.The results indicate that calculated results of coupled model show strong agreement with experimental data；in terms of oil film characteristics，increases of rotational speed lead to greater central oil film thickness，while pressure elevation results in reduces of oil film thickness at the center of high-pressure regions. The oil film pressure distribution exhibits periodic variation in sync with the plunger chamber pressure. Leakage increases markedly with both increases of pressure and speed，especially in high-pressure regions. The coupled model demonstrates superior predictive accuracy compared to conventional decoupled approaches.The research provides important theoretical support for the design of axial piston pumps.
