利用分离式 Hopkinson 压杆（SHPB）技术对爆炸箔起爆器（EFI）进行过载研究，通过实验分析了 EFI的外形变化、桥路电阻变化、内部损伤等，确定了EFI的失效模式；此外，采用有限元分析软件ANSYS/AUTODYN研究了EFI在不同加载速度条件下的变形情况及应力分布，进一步分析确定EFI的失效模式及失效原因，并说明采用SHPB分析EFI高过载是可行的。

Using split Hopkinson pressure bar (SHPB) technique, the overload study of exploding foil initiator was carried out, the deformation of EFI, the change of bridge resistance and internal damage were analyzed through the experiment, as well as the failure mode of EFI was determined. Meanwhile, through finite element analysis software (ANSYS/AUTODYN), the deformation and stress distribution of EFI at different load speed were obtained, and the failure mode and failure cause of EFI were analyzed further. The study indicated that using SHPB to analyze the overload of EFI is feasible.
