摘要：

基于快速制造样件以及铆接防水的需求，设计了一种分体式铆钉。以2层1.5 mm厚度的Al6016-T4铝板的铆接成形为研究对象，选择铆钉本体头部高度和内径、铆钉本体腿部内径以及压边力为影响因素，将互锁长度作为评价指标。基于4因素3水平的正交试验及Deform-2D软件对分体式铆钉铆接成形工艺参数进行优化。通过极差分析得到工艺参数对互锁长度影响的主次顺序为：铆钉本体腿部内径>铆钉本体头部高度>铆钉本体头部内径>压边力。基于正交试验结果分析得到最优铆接成形参数，并对优化方案进行试验验证，仿真值与试验值之间的相对误差为8.69%，证明了模拟结果的准确性，研究结论对实际生产具有指导意义。

Based on the needs of rapid manufacturing of sample piece and waterproofing of riveting, a split rivet was designed. Then, for the riveting forming of two layers of Al6016-T4 aluminum sheet with the thickness of 1.5 mm, taking the height and inner diameter of rivet head, inner diameter of rivet leg and blank holder force as the influence factors, and taking the interlocking length as the evaluation index, the riveting forming process parameters of split rivet were optimized by the orthogonal test of four factors and three levels and the software Deform-2D. Range analysis show that the influence order of process parameters on the interlock length is inner diameter of rivet leg>height of rivet head> inner diameter of rivet head > blank holder force. Then the optimal riveting parameters were obtained based on the analysis result of orthogonal test, and the optimization scheme was verified by experiments. The relative error between the simulated and experimental values is 8.69%, indicating the accuracy of the simuletion results, which hes guiding implications for the actual production.
