摘　　要：以2017材料的φ6 mm×16 mm铆钉为对象,基于Simufact.Forming有限元软件,运用点历史追踪法对其旋铆成形过程进行数值模拟研究,分析旋铆过程中的等效应力变化及应力分布情况,以及成形载荷变化规律及其影响因素。分析结果为某产品的旋铆工艺应用提供了理论依据。For ?6 mm×16 mm rivet of 2017 materials as object, based on Simufact. Forming finite element analysis software, point tracking method was used for the riveting process numerical simulation. The equivalent stress variation and stress distribution in the spin riveting process were analyzed, as well as the forming load changing rules and its influence factors. The results provide a theo?retical basis for the application of spin riveting process for a product.
