摘　　要：通过借助有限元仿真软件DEFORM-3D建立平锥头铆钉的沉墩头型干涉配合铆接模型,模拟单个铆钉的干涉配合铆接动态过程,测量在不同钉孔工艺参数下沿钉孔轴向方向上各测量点的径向位移,计算出铆钉与钉孔之间的相对干涉量.通过分析干涉量对铆接件疲劳寿命性能的影响,得到合理的干涉配合铆接钉孔工艺参数,并得到直径为5mm的平锥头铆钉干涉配合所需要的精确铆接力,为实际的工艺试验验证和生产工作提供可靠的理论数据.By using the finite element analysis software DEFORM-3D,the models for flat cone head rivets were established under the technological condition of countersunk head interference-fit riveting.The dynamic process of interference-fit riveting of a single rivet was simulated.The radial displacement at a series of measuring points along the axial direction of nail holes under different technological parameters were measured,and the relative amount of interference between the rivets and rivet holes were calculated.The effect of interference amount on the fatigue life of structure was analysed.The reasonable parameters for aperture processing were achieved and the necessang riveting force for 5 mm diameter flat cone head rivets was accurately estimated.The study provides reliable dates for actual process test and production.
