轴承的润滑性能是由低摩擦和高承载能力决定的，从理论上讲，部分滑移或非均质滑移表面设计可以促进这一点。本文采用临界剪应力模型，对静止滑动滑块表面与运动防滑面之间的二维润滑接触进行了数值分析。研究了边界滑移临界剪应力准则松弛条件下滑块表面滑移区域的扩散问题。在此基础上，提出了两种局部滑动模式，即侧向中心条纹和逆三角形。通过滑块轴承的数值和实验验证了这两种新的部分滑移模式，表明滑块轴承承载能力的提高超出了经典雷诺方程的预测。
The lubrication performance of a bearing is determined by low friction and high load carrying capacity, which can be theoretically facilitated by partial-slip or heterogeneous-slip surface design. In the study, we numerically analysed a two-dimensional lubricated contact of a stationary slip slider surface and a moving non-slip plane by using the critical shear stress model. The proliferation of slip region on a slider surface with the relaxation in the critical shear stress criterion for boundary slip was examined. Insights were extracted from the results, and two partial-slip patterns, namely, lateral central stripe and inverse triangle, were proposed. These two new partial-slip patterns were validated numerically and experimentally through slider bearing tests, which demonstrate that the bearing load carrying capacity was enhanced beyond the predictions of the classical Reynolds equation.
