A Simplified Piston-Ring Assembly Friction Model
Abstract
This paper presents a simplified and efficient piston ring assembly (PRA) friction model of the piston ring pack. The model, which considers both mixed and hydrodynamic lubrication, uses the Reynold’s equation as a governing equation and simplified assumptions to include mixed lubrication. Unique Stribeck curves are generated for a given ring’s geometry and inter ring starvation effects are introduced by varying the boundary conditions, as appropriate. The model is validated by measurements made on a single cylinder diesel engine.
