Mechanics and Stress Analysis of Piston Ring In Multibody Single Cylinder Internal Combustion Engine - Fe Analysis 2001-01-3371
This paper presents the results of the simulation of a piston ring in a multibody single cylinder internal combustion engine using explicit Finite Element analysis. The Finite Element model comprises of an assembly of piston, top compression ring, liner, connecting rod and crankshaft. The ring geometry, its coating and coating methods, its mechanical and its thermal properties are factors which influence engine performance. Deformation in the ring, the stresses developed therein and ring-liner clearance have been determined. This approach to engine design reduces the conceptual design-to-development cycle time and reduces the need of extensive engine testing for evaluating ring performance. The information obtained from the analysis serves as input for ring design and for development of coating techniques.
