建立了轴向柱塞泵滑靴副的热弹流润滑模型。该模型考虑了弹性流体动力学行为和粘温效应的相互影响。讨论了滑靴的变形情况，以及滑靴内油膜厚度、压力和温度的分布。研究了工况条件和滑靴结构参数对TEHD润滑性能的影响，如膜厚、压力、温度和泄漏流量。预测的温度和膜厚与测量结果吻合较好，而压力分布与以前的研究相比，显示出合理的。分析了载荷压力和轴转速对TEHD润滑特性的影响，指出在滑靴结构参数优化设计时，应考虑弹流压力与油膜温度、压力的平衡。最后，对滑靴半径比、节流孔长径比等滑靴结构参数进行优化，以提高滑靴副的TEHD润滑性能。
A novel thermoelastohydrodynamic (TEHD) lubrication model has been developed for slipper pair in axial piston pump. The model considers the interaction between elastohydrodynamic behavior and viscosity temperature effect. Deformation of the slipper is discussed as well as the distribution of oil film thickness, pressure and temperature. Effects of working conditions and slipper structure parameters on TEHD lubrication performance, such as film thickness, pressure, temperature, and leakage flow rate are investigated. The predicted temperature and film thickness show good agreement with measurements, while the pressure shows a reasonable distribution comparing with previous studies. The influence of load pressure and shaft rotational speed on the TEHD lubrication characteristics are illustrated which shows the elastohydrodynamic pressure should be balanced against the oil film temperature and pressure in optimized design of slipper structure parameters. Finally, the structure parameters of slipper, such as the slipper radius ratio and orifice length-diameter ratio, were optimized to improve the TEHD lubrication performance of slipper pair.
