摘要：
As a key structure of the Body-in-White（BIW），a reasonable joint design is of great signifi⁃ cance for the improvement of the load-bearing capacity of the BIW. Taking the lower joint of the B pillar as the re⁃ search object，a universal structure design method for body joints based on the load-bearing characteristics of thin plates is proposed in this paper. Firstly，the load type，force transmission mode and load-bearing characteristics of the thin plate structure are described to provide a theoretical basis for the subsequent universal joint structure. Sec⁃ ondly，the load conditions of joints are identified through sensitivity analysis，which is used to analyze the load-bearing characteristics of the thin plate of the joint. Then the design rules for the thin plate of T-joints are estab⁃ lished and the universal structure design of the joint is summarized. Application examples and tests show that the joint stiffness and BIW torsional stiffness is increased by 35% and 8.5% respectively，while the weight is only in⁃ creased by 0.16%. The method can quickly and effectively improve joint structure design and enhance body stiffness. © 2023 SAE-China. All rights reserved.
