Rapid Prediction of Roughness Effects in Sliding EHL Contacts

Popis výsledku v původním jazyce

The surface roughness represents an important issue from many tribological aspects for several decades. Roughness features in elasohydrodynamically lubricated (EHL) contacts substantially affect minimum film thickness, pressure distribution and thus havea great influence on friction, wear and fatigue life. However, surface roughness deforms inside contact and its omission can be oversimplification of the problem. Therefore, it is important to be able predict effects connected with surface roughness todesign surface pattern performance. The amplitude attenuation theory provide rapid tool to obtain roughness deformation and associated pressure fluctuations. It is based on the description of essential harmonic surface components with given amplitude andwavelength. This study further extends the model under rolling-sliding conditions with the aim present the complete and simple definition. The possibilities of the model are shown on practical case of surface indentation effects in EHL c
