采用分离式霍普金森压杆（ SHPB）技术研究了过载冲击对针刺延期火工品性能的影响，利用工业CT技术对针刺延期火工品结构损伤进行了分析，结果表明，过载冲击对针刺延期火工品结构损伤与性能影响有明显不同，过载后装药界面发生位移，发火感度降低，延期时间变短，精度变差，但能量输出变化不大。

The Split Hopkinson Pressure Bar ( SHPB) test was use to study the performance of stab delay initiating device affected by overload shock.The structural damage of stab delay initiating device was analyzed by CT.Results show that performance and structural damage of stab initiating device are distinctly different after overload test.When the interface of initiating device charge moves, the delay time becomes short, and the sensitivity of stab delay initiating device decreases after overload, the energy output do not change much.
