摘　　要：针对半导体桥火工品高过载模拟试验对加速度峰值(15×10^(4)g)和脉宽(200μs)的要求,对现有空气炮高过载模拟试验装置进行了改进,既改变火工品试样放置位置并将其置于工装靶中,通过子弹撞击带有整形器的工装靶,实现对侵彻高过载环境的模拟,并通过仿真和试验研究了工装靶质量、子弹质量和初速、整形器尺寸等参数对加速度峰值和脉宽的影响。结果表明:当工装靶质量为1000g、子弹质量为1500g、子弹初速为250m/s、整形器尺寸为Φ40mm×20mm时,仿真得到的加速度峰值为16.05×10^(4)g、脉宽为203μs;试验得到的加速度峰值为16.3×10^(4)g,脉宽为204μs。Aiming at the requirements of acceleration peak value and pulse width for high overload simulation test of semiconductor bridge initiating explosive devices,the existing high overload simulation test device of air gun was improved.By changing the placement position of the test sample and placing it in the tooling target,and impacting the tooling target with the shaper by the bullet,the simulation of high overload environment of penetration is realized.The effects of tooling target mass,bullet mass and its initial velocity,as well as shaper size on acceleration peak and pulse width were studied by simulation and test.The results show that when the mass of the tooling target is 1000g,the mass of the bullet is 1500g,the initial velocity of the bullet is 250m/s,and the size of the shaper isΦ40mm×20mm,the simulated peak acceleration is 16.05×10^(4)g and the pulse width is 203μs,the peak acceleration obtained from the test is 16.3×10^(4)g,and the pulse width is 204μs.
