为提高燃料空气炸弹的释能效率，研究中心装药的起爆方式对燃料空气炸弹爆炸威力的影响。建立1点、2点、5点起爆方式的仿真模型，运用 AUTODYN 软件，对中心装药起爆过程中的最大压力和最大抛撒速度进行仿真计算，并对爆轰波传播过程进行分析。仿真结果表明：在3种起爆方式中，2点起爆能够形成扁平状火球，作用区域更广；2点起爆的峰值可以达到其他2种起爆方式的2倍左右；2点起爆和5点起爆情况下的燃料抛撒的速度比一点起爆可提高19%。

For improving energy releasing efficiency of fuel air explosive (FAE), research on influence of center charge ignition method on FAE explosion strength. Establish ignition simulation modes of 1 point, 2 points and 5 points, use AUTODYN software, on the center charge blasting fling at the maximum stress and maximum speed in the process of simulation computation, the detonation wave propagation process is analyzed. The simulation results show that: in 3 ignition methods, 2 points detonation can form flat fireballs, function area is more extensive; 2 points blasting peak can reach around twice of the other two ignition methods; 2 points detonation ignition and 5 points cases of fuel can increase 19% than 1 points initiation.
