基于润滑剂在弹性流体动力润滑状态下表现出类似塑性固体的非牛顿特性，根据塑性屈服和流体动力润滑理论，建立了考虑润滑剂在固液界面滑移的线接触弹流润滑失效预测模型．计算结果显示：载荷和滑滚比对润滑油膜厚度影响显著；在一定载荷和滑滚比下，润滑油膜将丧失承载能力而破裂．与现有理论及实验数据对比，线接触弹流润滑失效预测模型的计算结果与实验结果具有较好的一致性．
Based on the non-Newtonian behavior of the lubricant in the elastic hydrodynamic lubrication state, the model is established based on the plastic yielding and hydrodynamic lubrication theory, and the failure prediction model of the line contact elastohydrodynamic lubrication considering the slippage of the lubricant at the solid-liquid interface is established. The calculated results show that the load and slip ratio have a significant effect on the lubricant film thickness. Under a certain load and slip ratio, the lubricant film will lose its bearing capacity and rupture. Comparing with the existing theoretical and experimental data, the calculation results of the line contact EHL failure prediction model are in good agreement with the experimental results.
