| Abstract: | Based on the structural finite element method,the fatigue strength for rapid wagon wheel web was analyzed by using the mechanical design loads and load cases provided by Europe railway and Japanese railway respectively.The calculating results show that the fatigue behavior of wheel web can satisfy the requirement of infinite life design criteria.Its fatigue weak positions are located in the arc transition zones between inner surface of web and wheel hub. |
