GuYan condensed joint model used in the car body

摘要

The joint characteristics should be determined in the early stage of a car body design. In this study, the joint characteristics of a car body were expressed through the GuYan condensed model. The condensed joint model was applied to A-pillar upper joint of car body. In addition, it was applied to the car-body simplified model with beams and GuYan condensed joints (Model II). And we established the car-body simplified model with beams and detailed joints (Model I). It confirms the exactitude and effectiveness of this method through the results of static analysis and modal analysis of the two models.
