| 摘 要： | 针对分离式霍普金森压杆(SHPB)试验无法用加速度描述其对火工品的影响问题,利用空气炮和SHPB试验后所得的半导体桥火工品轴向应变、作用时间和芯片发火能量等结果,将空气炮试验的加速度等效至SHPB试验的子弹速度上,获得了SHPB试验的子弹速度与加速度的等效方程。建立了基于SHPB试验的火工品加速度力学过载模拟试验方法。

| Abstract: | Since the split Hopkinson pressure bar (SHPB) test can not describe the effect problem on pyrotechnics using acceleration, an equivalent equation of bullet speed and acceleration of SHPB test was obtained using results of SCB pyrotechnics from by air cannon and SHPB tests, such as axial strain, time to reaction, chip firing energy etc and taking that the acceleration of air cannon test is equivalent to the bullet speed of the SHPB test. An overload acceleration mechanics simulation test method of pyrotechnics for SHPB test is established finally. |
