Aiming at the seam weld fatigue cracking problem of a commercial vehicle suspension, the actual road load data are tested and extracted, and the rigid flexible hybrid multi-body dynamic model of the cab and suspension system is established. The drives of the suspension subsystem are obtained through virtual load iteration, and the mode participation factor and the full field time-domain stress amplitude are obtained. A weld fatigue analysis method based on improved notch stress method is established, and the calculation results of various modeling methods are compared. It is proved that this weld fatigue analysis method has high calculation accuracy and mesh insensitivity which improves the engineering application of notch stress method, and provides a new guiding direction for life prediction and forward design of automobile weld structure.
