Abstract In the present work, a CFD numerical investigation of the tribological characteristics of parallel and quasi-parallel slider bearings has been performed. The work is initiated following experimental observations of load carrying capacity on parallel thrust bearings. The computational results conclude that the principal mechanism of pressure build-up is the hydrodynamic wedge generated due to thermal deformation of the active pad surface. The calculated final geometry of the pad consists of a converging region, extending from the oil entrance to the maximum pressure region, and a diverging region extending from the maximum pressure region to the oil outflow. Finally, initial surface defects of the pad active surface, contribute moderately to building-up the final load carrying capacity of the slider.

在 ThermoElastoHydroDynamic (TEHD) 状态下运行的平行和准平行滑动轴承的数值研究

摘要 在目前的工作中，对平行和准平行滑动轴承的摩擦学特性进行了 CFD 数值研究。这项工作是在对平行推力轴承的承载能力进行实验观察后开始的。计算结果得出结论，压力积聚的主要机制是由于活动垫表面的热变形而产生的流体动力楔。计算出的垫的最终几何形状包括一个收敛区域，从油入口延伸到最大压力区域，以及一个从最大压力区域延伸到油流出的发散区域。最后，垫有源表面的初始表面缺陷对建立滑块的最终承载能力有适度的贡献。
