| Abstract: | In order to accurately simulate fatigue life distribution of a new locomotive coupling,this paper presents load spectrum for fatigue life simulation of the coupling combined with practical load carrier.Applying the method of quasi-static stacking and the theory of linear cumulative damage,the fatigue life of new locomotive coupling has been simulated based on ANSYS finite element analysis software and n-Code fatigue analysis software.The coupling fatigue life is also calculated enduring the impact of transi... |
