| 摘 要： | 铆接工艺参数对自封铆接干涉量产生重要影响。采用有限元仿真软件DEFORM-3D,以2117-T4材料、直径4mm的半圆头自封铆钉及2024-T3材料的铝板为研究对象,分析自封铆接的3个主要工艺参数钉孔直径、顶铁形状及压铆力对铆接质量的影响。仿真结果表明,钉孔直径范围在4.01~4.02mm,采用凹槽顶铁及较大的压铆力会增加铆接干涉量,提高铆接件的密封性能。

| Abstract: | Riveting process parameters have an important effect on interference in self-sealing riveting.Based on DEFORM-3D software,4mm round head self-sealing rivets made of 2117-T4,and panels of 2024-T3 are discussed to analyze the effect of three main process parameters,which are hole-diameter,iron shape and pressing force on riveting quality.The simulation results show the riveting interference can be increased within 4.01-4.02mm hole-diameter,by using groove iron and high-pressing force.Therefore,the sealing performance can be improved. |
