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.

轴承的润滑性能取决于低摩擦和高承载能力，从理论上讲，这可以通过部分滑动或非均匀滑动表面设计来实现。在研究中，我们使用临界切应力模型对固定滑动滑块表面和运动防滑平面的二维润滑接触进行了数值分析。检验了滑动器表面上滑动区域的扩散以及边界滑动的临界剪切应力准则中的松弛。从结果中提取了一些见解，并提出了两个局部滑移模式，即侧向中心条纹和反三角形。通过滑动轴承测试，对这两个新的局部滑模进行了数值和实验验证，
