摘　　要：为有效预测碳纤维增强复合材料(carbon fibre reinforced polymer,CFRP)层压板的雷击电弧附着响应,并探讨阳极试件材料对雷电电弧参数空间分布的影响,基于商业有限元分析软件ABAQUS,分析了CFRP层压板雷电流注入后的热-电-结构耦合,建立了CFRP层压板电弧附着损伤的三维有限元模型。模拟了复合材料层压板在雷电流作用下的冲击响应,进行了复合材料层压板雷击附着机理和作用模式的分析,并探讨了试件尺寸对电弧附着响应特性的影响。研究结果表明,当CFRP试件的长宽比接近1时,CFRP损伤区域往往集中在准静态电弧附着处,与其他长宽比相比,损伤面积较小,但损伤深度较深。In order to effectively predict the lightning arc attachment response of carbon fibre reinforced polymer(CFRP)laminates and explore the influence of anode specimen material on the spatial distribution of lightning arc parameters,on the basis of the finite element analysis software ABAQUS,the thermal-electrical-structural coupling of lightning current injected into CFRP laminates was analyzed,and a three-dimensional finite element model of the arc attachment damage was established.The impact response of composite laminates under lightning current was simulated,the mechanism and mode of lightning strike attachment were analyzed,and the influence of specimen size on arc attachment response characteristics was discussed.The results show that the damage regions tend to be centralized at the arc attachment when the aspect ratio of the CFRP specimen is close to 1,and the specimen shows smaller damage area but severer damage depth compared to other aspect ratios.
