Abstract

This paper presents a review of existing methodologies for predicting stress and strain development in automotive plain bearings. Initially, it deals with the modelling of the forming and fitting operations, leading to the determination of residual stresses, then with the numerical processes of generating cyclic stresses and plastic strains due to the reciprocating engine forces. Modelling tools as well as their adopted assumptions and simplifications are explained. Particular attention is given to the distinction between and effects of hydrodynamic and elastohydrodynamic lubrication conditions. The output of such analyses is illustrated through the inclusion of some typical results; its significance is discussed in the context of bearing design against fatigue failure. Keywords: plain bearings, stress analyses, bearing forming, bearing fitting, elastohydro dynamic lubrication.
