Effet des paramètres de conception du piston sur le frottement jupe-chemise

Abstract

A mixed lubrication model is presented in this paper. It is developed for use in conjunction with a piston secondary motion analysis. Some parameters affect this kind of movement as the elasticity of the skirt and its profile shape (flat or curved). The results show that these parameters have a great influence on the friction forces, and therefore, they have the potential to optimize the piston friction power loss. © 2009 AFM EDP Sciences.
