Abstract
In this paper, the mass-conserving formulation first proposed by Giacopini et al. in [12] and then extended in [13] to include compressibility and to study non-Newtonian fluids is further improved to consider the elastic deflection of the solid surfaces. This formulation is essentially based on a manipulation of the Reynolds equation that allows the lubrication problem in the presence of cavitation to be described as a simple Linear Complementarity Problem (LCP). In particular, this algorithm is here applied to the EHL analysis of the lubrication performance of one of the connecting rods big-end bearing of a spark ignition motorsport engine under dynamic loadings.
