STUDY ON CRACK PROPAGATION CHARACTERISTICS OF COUPLER BASED ON SUB-MODEL

STUDY ON CRACK PROPAGATION CHARACTERISTICS OF COUPLER BASED ON SUB-MODEL

In order to ensure safe operation of heavy haul train and maintenance cost control of coupler,sub-models containing elliptical surface crack are established on fatigue crack zones of the coupler body and knuckle. Finite element method and interaction integral method are combined to analyze the stres...
