摘　　要：采用霍普金森压杆试验方法对针刺火工品壳体形变进行了研究,并用ANSYS/LS-DYNA软件对过载冲击下针刺火工品壳体各特征部位的受力情况进行了数值模拟分析,得到了耐高过载针刺火工品壳体形变变化规律,明确了针刺火工品在过载冲击载荷下导致结构失稳的薄弱部位,为以后耐高过载针刺火工品设计提供理论参考。The deformation of stab initiator was tested by SHPB, and the deformation state of each part was simulated by use of ANSYS/LS-DYNA. The deformation change rule of anti-overload stab initiator was obtained, as well as the weak parts which may affect the whole stability of stab initiator were determined. The study can be used as academic reference and guidance for anti-overload design of stab initiator.
