摘　　要：无钉铆接作为汽车白车身的主要连接方法之一,其连接质量一直被各汽车厂家所重视。文章利用有限元仿真软件Abaqus,通过正交设计方法,对无钉铆接的铆接过程及拉伸破坏过程进行了仿真研究,得到了影响铆接质量的3组工艺参数的影响权重,并用实验对仿真数据进行了验证。实际应用表明,分析得出的参数权重能够在冲压铆接强度发生波动时,合理地判断出影响强度的主要因素,有效提高了铆接质量的稳定性。As one of the major joining processes for body-in-white（BIW） assembly, the clinching joint quality has always been a concern of auto makers. In this paper, the clinching process and the process of joint de- struction are researched by using the orthogonal design method via the finite dement simulation software Abaqus. The results confirm the different influence levels of three groups of process parameters on the joint quality, and the simulation data is verified by experiment. The results of practical application show that the results of analysis can determine the main reason for the fluctuation in joint strength, and effectively improve the stability of joint quality.
