利用动态模拟装置测试和研究了雷管和火帽两种典型针刺火工品在动态击发条件下的发火性能，获得了动态发火性能数据，与落球仪的测试结果和经典公式E_f＝E_0·e~(-0.1v)计算结果进行了对比分析，得出击针质量对数1nM与击发速度V有良好的负的线性相关关系，用二维随机变量联合分布法可更确切地表达火工品针刺感度等有用的结果。
The dynamical performance of two typical acupunctures of detonator and fire cap under dynamic firing conditions was tested and studied with the dynamic simulator. The dynamic firing performance data were obtained, and the results of the ball drop test and the classical formula E_f = E_0 · e ~ (-0.1v). The results show that there is a good negative linear relationship between 1nM of firing pin mass and firing rate V, and the two-dimensional random variable joint distribution method can express pyrotechnic needle more accurately Thorn sensitivity and other useful results.
