摘要To investigate the influence of surface texture on traction characteristics of wheel/rail under mixed lubrication, laser dispersed treatment was used to form texture patterns, such as longitudinal, transverse and rhombus, on the surface of wheel discs. The film thickness and contact area ratio were calculated by using deterministic model instead of stochastic model. Based on the load-sharing concept, the hydrodynamic film and asperities both contribute in carrying the total load. Therefore the traction force is composed of two components: hydrodynamic traction force and asperity traction force. The tribological tests were conducted on an Amsler type wear testing machine. It is shown that the traction coefficient of rhombus pattern is higher than that of longitudinal and transverse, while the latters are similar. Though the asperity orientation of longitudinal and transverse is different, their influence on traction coefficient under mixed lubrication should be investigated further. © Civil-Comp Press, 2014.
