Thermomechanical Fatigue Life Prediction for a Marine Diesel Engine Piston considering Ring Dynamics

Thermomechanical Fatigue Life Prediction for a Marine Diesel Engine Piston considering Ring Dynamics

A newly designed marine diesel engine piston was modeled using a precise finite element analysis (FEA). The high cycle fatigue (HCF) safety factor prediction procedure designed in this study incorporated lubrication, thermal, and structure analysis. The piston ring dynamics calculation determined th...
