Plain bearing stresses due to forming and oil film pressure

Burke-Veliz, A., Wang, D., Wahdy, N., Reed, P.A.S., Merritt, D. and Syngellakis, S. (2009) Plain bearing stresses due to forming and oil film pressure At 7th International Conference on Modern Practice in Stress and Vibration Analysis. 08 - 10 Sep 2009. 8 pp.

Record type: Conference or Workshop Item (Paper)


This paper describes a methodology for assessing critical stress ranges arising in automotive plain bearings during engine operations. An industry-produced and run simulation program provides information on oil film pressure and overall bearing deformation during accelerated performance tests. This code performs an elasto-hydrodynamic lubrication analysis accounting for the compliance of the housing and journal. Finite element analyses of a multi-layer bearing are performed to assess the conditions responsible for possible fatigue damage over the bearing lining. The residual stresses arising from the forming and fitting process are first assessed. The stress analyses over the engine cycle show the intensity and distribution of cyclic tensile and compressive stresses in the bearing. The location of maximum stress range is found to be consistent with the damage observed in accelerated fatigue tests. Critical zones are identified in the lining for possible fatigue crack initiation and growth studies
