Purpose
– This paper aims to study the effect of piston skirt design parameters on the dynamic characteristics of a piston–cylinder contact.
Design/methodology/pproach
– This paper focuses on an analysis of the piston dynamic response. The oil-film pressure and the structural deformation were approximated, respectively, by finite difference method and finite element method.
Findings
– The results show that the design parameters such as clearance, offset and the axial location of piston pin have a great influence on the dynamics of the piston and hence on the piston slap phenomenon and the frictional power loss.
Originality/value
– All the results mainly focus on the slap noise of the engine and can be used in the piston–liner development at the development of the engine.
Cet article présente un modèle de lubrification mixte en conjonction avec une analyse du mouvement secondaire du piston. Certains paramètres influent ce genre de mouvement tel que l'élasticité de la jupe et la forme de son profil (plat ou bombé). Les résultats montrent que ces paramètres ont une grande influence sur les forces de frottement, et par conséquent, ils ont le potentiel pour optimiser la perte de puissance par frottement du piston.
