In vehicle braking systems, surface topography plays a critical role in friction, wear and overall function. Understanding how surface structures evolve over time and interact at different scales is therefore essential for improving tribological performance. This challenge is at the core of the research recently conducted by a team of French researchers from the LAMIH UMR CNRS 8201 and LaMcube UMR CNRS 9013 laboratories, authors of a scientific publication investigating multiscale topographical analysis of brake friction.
Researchers at the Luleå University of Technology and Scania in Sweden, recently investigated how surface topography influences oil film formation in tribological interfaces pertinent to gears. The study was oriented towards the improvement of fuel economy and sustainability. Jonny Hansen, a member of the research team, explains how Mountains® software was used to help achieve results.
An automotive manufacturer used Mountains® software to study parameters associated with wear and lubrication.
Friction, core and lubrication zones of a motor cylinder were studied in order to investigate opportunities for improving fuel efficiency and thus reduce harmful emissions. Mountains® software was used to provide advanced analysis of the volume of the zones studied.
