When it comes to the numerical evaluation of tribological contacts operated in the boundary and mixed lubrication regime, the estimation of the asperity contact based on statistical methods is widespread. We have studied the effects and expressiveness of major aspects of statistical contact modelling including the choice of contact model, surface evaluation method and magnification in the process...
The current work investigates the tribological functionality of crankshafts bearing systems focusing on the variation of shaft materials and their surface conditions. Tribological tests were carried out with a ring-on-disc test configuration representing the bearing-shaft contact under start–stop motion. Forged steel and cast iron shaft materials were sliding against an Al based bearing alloy. The...
