摘　　要：为解决玻璃钢(GFRP)与铝合金叠层压铆过程中对GFRP层的损伤问题,对典型GFRP/铝合金叠层开展了2A10材料Φ4 mm铆钉在不同大小预制孔和压铆力下GFRP材料损伤情况的有限元分析,得到了实现低损伤压铆的预制孔大小及压铆力范围;根据仿真结果开展了叠层压铆试验研究并对试片进行了无损检测、剪切强度分析。结果表明:GFRP/铝合金叠层在压铆过程中选用(18.5±0.2)kN压铆力、Φ4.2 mm预制孔可实现GFRP与铝合金叠层的低损伤压铆。In order to solve the damage to GFRP composite during the riveting process of multi-layer consisting of GFRP composite and aluminum alloy,the dynamic damage analysis of GFRP composite have been simulated by ABAQUS on the effects of diameter of pre-drilled hole and riveting squeeze ofΦ4 mm 2A10 aluminum alloy rivet.On the basis of the simulation the experimental investigations on multi-layer consisting of GFRP composite and aluminum alloy were performed.The non-destructive test and shear test of the specimens were conducted.Results of the analysis indicate that the adequate process parameters of Φ4.2 mm pre-drilled hole and(18.5±0.2)kN riveting force can achieve the requirements of low damage to GFRP composite.
