Abstract

The local fatigue performance of the framework joints of a coach is analyzed by the Beam-shell hybrid model.The impact of the weld spacing on the fatigue performance is studied,and the relationship between the fatigue life of the joints and the changed weld spacing is preliminarily summarized,providing a useful reference for the local structure design of the coach body.
