Analysis of Fretting Behavior for Fasten Surface between Diesel Engine Cylinder Block and Main Bearing Cap

Abstract:

Fretting fatigue becomes a typical failure mode for engine cylinder block caused by the increasing of the gas pressure and rotating speed, but the mechanism of fretting fatigue under diesel engine load condition hasn’t been systematic studied. In this paper, the fretting behaviors are mainly discussed by using fretting friction work parameter W and crack initiation location parameter G.
