摘要/Abstract

摘要： 平底无铆塑性连接铆接头的抗拉强度只能通过大量破坏性试验获得，且强度检测成本高、周期较长。重点分析铆接头在拉伸过程中的颈部断裂失效、拉脱失效及混合失效三种失效形式及成因；建立平底无铆塑性连接过程的数值模型，获得铆接头的剖面几何参数，通过铆接头的剖面观测试验验证数值模拟的精确性；借鉴管材拉拔过程中的主应力法，基于铆接头的剖面几何参数建立平底无铆塑性连接抗拉强度预测模型；进一步通过铆接头强度检测试验验证了抗拉强度预测模型的正确性，深入分析底厚值对抗拉强度的影响规律。结果表明，铆接头抗拉强度预测值与试验值最大误差为14.8%，其主要误差来源于铆接头加工硬化系数、摩擦因数、底厚值等参数；铆接头抗拉强度随着底厚值的减小呈递增趋势，当底厚值为0.50 mm时，Al5052-Al5052的抗拉强度最大，铆接头发生混合失效。建立一种高效、低成本的铆接头成形质量评价方式，对平底无铆塑性连接铆接头的几何参数优化具有指导意义。

Abstract: Flat clinching has become a research hotspot in the automotive lightweight technology field, but the strength of the clinched joint is obtained by many destructive tests. It has the disadvantage of high cost and long period. Therefore, three failure modes and causes of neck failure, pull-out failure and mixture failure during the tensile strength tests were analysed. The simulation model of flat clinching was established. The geometric parameters of the clinched joint were obtained, and the accuracy of the numerical simulation was verified through section observation tests of the clinched joint. The predictive model of tensile strength model was established based on the principal stress method during pipe drawing process. Further the correctness of the tensile strength predictive model was verified based on numerical simulation through the tensile strength tests. And the effect of bottom thickness on tensile strength was studied. The results show that the maximum error between predicted tensile strength and experimental value of clinched joints is 14.8%. The main errors are derived from the parameters such as work hardening coefficient, friction coefficient and bottom thickness of clinched joints; The tensile strength of clinched joints increases with the decrease of the bottom thickness. When the bottom thickness is 0.50 mm, the tensile strength of Al5052-Al5052 is the largest, and the clinched joints occurs mixed failure. An efficient and low-cost method for evaluating the forming quality of clinched joints is established, it also has important directive significance for the optimization of the geometric parameters of clinched joints in flat clinching.
