Wear Analysis of a Low-Speed Diesel Engine Connecting Rod Based on Orthogonal Simulation Test

Abstract As con-rod is a critical component in an engine, its reliability overwhelmingly directly affects the performance of whole diesel engine. The fretting wear bushing mainly occurs on contact surface with small end and cap. In proposed study, process end, cap under maximum combustion pressure condition was analyzed, distribution friction stress analyzed. Then orthogonal simulation test designed. According to mechanics theory, interference amount coefficient were taken as factors, objective functions. influence factors function most reasonable found, so slow down bushing.
