Abstract

The presence of rigid particulate contamination in hydrodynamic bearings is known to lead to considerable damage resulting in failure. This paper presents a model for evaluating the flash temperature between a fixed, rigid particle embedded into the bearing over-layer while in contact with the slider. Scuffing is assumed to occur if the flash temperature exceeds a certain critical value. The model provides a convenient procedure for estimating an appropriate filter size. Examples are provided to illustrate the utility of the model.
