摘要
通过碾铆连接和螺栓连接对复合材料-铝合金进行了连接实验,对两种连接方式的接头进行了静拉伸测试,对比分析了有无垫片和是否粘接两种因素对接头连接强度和能量吸收的影响。结果表明:添加垫圈后,两种接头的峰值载荷趋于一致,但螺栓连接接头的失效位移高于碾铆连接接头,且其能量吸收值比碾铆连接接头高16.29%,有更强的缓冲吸震能力;引入粘接对两种接头的抗拉伸强度影响不大,螺栓连接失效的峰值载荷略高于碾铆连接,两种接头的失效位移和能量吸收基本相同。
The connection experiments and static tensile tests of composite and aluminum alloy were carried out by the rolling riveting and the bolt connection. The effects of washer and bonding on the joint strength and the energy absorption were compared. The experiment results show that the peak loads of the two joints are almost the same,but the failure displacement of the bolt joint is longer than that of the rolling riveting joint when the washer exists.Furthermore,the energy absorption value of bolt joint is 16. 29% higher than that of the rolling riveting joint,and it has a stronger capacity to absorb vibration. The factor of bonding has little effect on the tensile strength of the two joints. In addition,the peak load of bolt connection is slightly higher than that of the roller riveting connection,and the failure displacement and energy absorption of the two joints are basically the same.
