The study presents a profile design method to improve the wear performance of misaligned water-lubricated bearing based on the modified Archard model. This method takes into account the variation of the film thickness under the mixed elastohydrodynamic lubrication (mixed-EHL). A transient hydrodynamic Reynolds equation model with the Patir–Cheng flow factors is used to predict the evolution of the mixed-EHL performance over time. The Archard model is extended to predict the time-varying wear based on the fatigue concept. To verify the effectiveness of the proposed profile design method; the simulation results, including the transient contact pressure, wear depth and wear volume, between the considering and not considering the profile design are compared. To gain insight, several illustrative examples are presented to show the amelioration of the profile design. Parametric studies are reported to show the applicability of the profile design and emphasise the profile height selection. Therefore, the profile design is an extraordinary method to reduce the edge wear.

一种提高错位水润滑轴承磨损性能的轮廓设计方法

研究提出了一种基于改进的 Archard 模型的轮廓设计方法，以提高错位水润滑轴承的磨损性能。该方法考虑了混合弹性流体动力润滑（mixed-EHL）下油膜厚度的变化。具有 Patir-Cheng 流动因子的瞬态流体动力学雷诺方程模型用于预测混合 EHL 性能随时间的演变。Archard 模型扩展到基于疲劳概念预测时变磨损。验证所提出的轮廓设计方法的有效性；比较了考虑和不考虑轮廓设计的模拟结果，包括瞬态接触压力、磨损深度和磨损量。为了获得洞察力，提供了几个说明性示例以显示轮廓设计的改进。参数研究报告显示轮廓设计的适用性并强调轮廓高度选择。因此，轮廓设计是一种减少边缘磨损的非凡方法。
