摘要：Of great concern for the automotive industry is the power lost to friction in the reciprocating components, in particular at the piston ring/liner contact. The piston rings seal the space between the piston and the liner, and act essentially as slider bearings subject to alternating motion. The numerical assessment of the ring/liner contact is very challenging due to the dynamical interaction of the oil film with the elastic rings, and the significant effect of cavitation and starvation phenomena. Important precedents can be found in the work of Priest and coworkers (e.g.; Proc. Inst. Mech. Engrs. 214:435-447, 2000).
