doi:10.3901/JME.2018.21.120

Abstract

Abstract: In order to improve the service performances of the friction surfaces, the influence of friction surface micro-topography machined by grinding and electrochemical finishing on micro-dynamic pressure effect is investigated by experimental test and simulation using the theory of fractal geometry and FLUENT software. The results show that electrochemical finishing can change the intensity distribution of the micro-dynamic pressure effect as a result of regularizing the surface micro-topography obtained by grinding. The transmission is the result of the balance among the lots of the micro-dynamic pressure effect which are generated by micro-topography of surface and are different in intensity of the pressure, and makes up an uneven distribution pressure field. Compared with the surface machined by grinding process, the surface contained by the electrochemical finishing is favorable in improving friction coefficient, wear and vibration.

Key words: dynamic pressure effect, fractal geometry, integration, micro-topography of surfaces, transmission
