摘要
用同种AA5052铝合金板材进行了压印-粘接复合连接、自冲铆-粘接复合连接和点焊-粘接复合连接试验,比较了三种连接接头的失效模式,分析了连接接头的拉剪载荷-位移曲线及能量吸收值图。结果表明,自冲铆-粘接复合连接和点焊-粘接复合连接最大平均失效载荷值较大,压印-粘接复合连接最大平均失效载荷值为自冲铆-粘接复合连接最大平均失效载荷值的89%,为点焊-粘接复合连接最大平均失效载荷值的83.89%;自冲铆-粘接复合连接的能量吸收值是压印-粘接复合连接能量吸收值的6.32倍,点焊-粘接复合连接的能量吸收值是压印-粘接的5.52倍。通过三种连接方式的对比分析,自冲铆-粘接复合连接能够更好的满足静力学性能要求,并且缓冲能力较好。
The clinch-bonded plate joint, self-pierce riveting-bonded plate joint and spot welding-bonded plate joint with the same kind of AA5052 aluminum alloy plate were carried out to compare three failure modes of joints and the connection load-displacement curves and energy absorption value figure were analyzed.The results show that the self-pierce riveting-bonded plate joint and the spot welding-bonded plate joint have a larger maximum average failure load value, and the maximum average failure load value of clinch-bonded plate joint is 89% of the maximum average failure load value of the self-pierce riveting-bonded plate joint, which is 83.89% of the spot welding-bonded plate joint. The energy absorption value of the self-pierce riveting-bonded plate joint is 6.32 times of clinch-bonded plate joint. The energy absorption value of the spot welding-bonded plate joint is 5.52 times of clinch-bonded plate joint. Through the comparative analysis of the three connection methods, the conclusion is drawn that the self-piercing riveting-bonded plate joint can better meet the static performance requirements and has better buffering capacity.
