Based on VPG load spectrum as the input,through the establishment of finite element simulation model of car body based on nCode fatigue analysis software,in the early stage of the body during the development process,the study on fatigue analysis of a SUV.Analysis results show that the lateral confining the back-end solder joints and trailing door frame coaming sheet metal parts after fatigue damage value is too large,may cause the cracking problems,improvement measures are put forward,provides the reference basis for the preliminary design of car body.
