Aiming at the problem of solder joint opening between front wheel cover plate and auxiliary water tank mounting bracket assembly in the process of PAVE test of a vehicle body structure, this paper finds out the failure reason of solder joint through structural stress analysis, and investigates several types of vehicle, combines CAE simulation analysis and vehicle’s own characteristic structure, puts forward two improved design schemes, considers each factor synthetically, and chooses the development scheme. A scheme with better cost and development cycle. The validation of the improved scheme shows that it not only effectively solders the solder joint opening problem between the front wheel cover plate and the auxiliary water tank mounting bracket assembly, meets the vehicle PAVE road test target requirements and improves the vehicle body reliability, but also takes into account the structural weight, setting cost and other factors, which is conducive to the lightweight design of the car body in white, and proves the effectiveness of the improved scheme.
