Low Cycling Thermal Fatigue of Large-Scale Marine Diesel Engine Piston

Abstract:

According to the fatigue and fracture reliability theory, the criterion of piston fatigue crack growth rate da / dN is induced using set-value theory of fatigue and fracture mechanics on the basis of actual safety and life of the marine diesel engine piston. Life analysis and security evaluation of large marine diesel engine piston was implemented with this criterion, which affords an important reference for the application of large marine diesel engine.
