Abstract In the study of elastohydrodynamic lubrication the rheological properties of the liquid film are essential to understanding and predicting the friction and the film thickness in lubricated concentrated. There are two entirely different approaches to obtain these properties. In the quantitative approach, viscometers and rheometers are used at high pressure. In the classical approach, the same averaged properties are extracted from the contact itself. For more than 40 years the two methods have provided quite different pictures of high-pressure rheology. The claim has been made that the averaging technique provides viscosities that match those from this author's rheometer and viscometer. This claim can easily be shown to be false and the use of the contact as a viscometer must end.

是否有可能从 EHL 摩擦中提取低剪切粘度的压力依赖性？2020 年 5 月修订

摘要 在弹性流体动力润滑研究中，液膜的流变特性对于理解和预测润滑集中的摩擦和膜厚至关重要。有两种完全不同的方法来获得这些属性。在定量方法中，粘度计和流变仪在高压下使用。在经典方法中，从接触本身提取相同的平均属性。40 多年来，这两种方法提供了完全不同的高压流变学图片。有人声称平均技术提供的粘度与作者的流变仪和粘度计的粘度相匹配。这种说法很容易被证明是错误的，必须停止将触点用作粘度计。
