Residual And Cyclic Stresses In Automotive
Plain Bearings

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.
