dc.description.abstract | The reduction of friction and the limitation of emissions of greenhouse gases are the main objectives of the automotive industry. This energy e ciency is related to functionalization of the surface of ringpack tribo-system. Multi-stage abrasive nishing process are commonly used to produce the geometrical properties of a surface. This confers technical some functionalities in the operating characteristics relating to their durability and reliability. The texture generated signi cantly a ects the performance of the ring-pack system. In this paper, a numerical model of elasto-hydrodynamic (EHD) contact coupled to a multiscale surface texture modeling was developed. This permtis to to study the scale e ect of surface features and theirs interactions on friction performance and lubricant ow under hydrodynamic lubrication condition. Surface topography can be decomposed in two principal components : super cial roughness modeled using fractal model and valleys modeled by scaling factor. Results show Relationship between friction and surface scales. |
