Abstract The Stribeck curve shows the friction coefficient as a function of speed, viscosity and load. The viscosity times speed over load parameter can be interpreted as a film thickness. The film thickness over roughness parameter unifies friction curves in the isoviscous rigid regime. In this paper, the Stribeck curve is predicted numerically in the full-film Elastohydrodynamic Lubrication regime. It is shown that the lambda ratio is not the most appropriate parameter. A more elaborate parameter including the operating conditions and based on the Amplitude Reduction Theory [1] gives much better results. For a complex surface topography, the full numerical simulation is time-consuming. A rapid prediction method is proposed. Good agreement is found between the full numerical simulation and the prediction.

全膜弹性流体动力润滑下的 Stribeck 曲线预测

摘要 Stribeck 曲线显示摩擦系数是速度、粘度和载荷的函数。粘度乘以负载速度参数可以解释为薄膜厚度。膜厚超过粗糙度参数统一了等粘性刚性区域的摩擦曲线。在本文中，Stribeck 曲线在全膜弹性流体动力润滑方案中进行了数值预测。结果表明，λ 比率不是最合适的参数。一个更详细的参数，包括操作条件和基于振幅减小理论 [1] 给出了更好的结果。对于复杂的表面形貌，完整的数值模拟非常耗时。提出了一种快速预测方法。在完整的数值模拟和预测之间发现了良好的一致性。
