摘　　要：为研究圆台形燃料空气炸药(FAE)装置燃料抛撒运动特性,利用ANSYS/LS-DYNA软件对燃料初始抛撒过程进行了数值模拟,得到了不同位置处的燃料抛撒初速,分析了中心抛撒药结构对燃料抛撒的影响,并进行了实验验证。结果表明:圆台形FAE装置不同位置处的燃料抛撒初速与截面比药量有关,燃料抛撒初速随截面比药量的增加而增加;相较于等直径中心抛撒药,采用变直径中心抛撒药时截面比药量一致性更好,有利于减小不同位置处燃料抛撒的速度差。In order to study the motion characteristics of fuel dispersal in cone-shaped FAE device,the process of initial fuel dispersal was numerically simulated by ANSYS/LS-DYNA software,the initial velocity of fuel dispersal at diffe-rent positions was obtained,and the influence of central dispersal structure on the fuel dispersal was analyzed.The results show that the initial velocity of fuel dispersal at different positions of the cone-shaped FAE device is related to the specific charge amount of the cross section,and the initial velocity of fuel dispersal increases with the increase of the specific charge amount of the cross section.Compared with the uniform diameter center dispersal,the consistency of the specific charge amount of the cross section is better when the variable diameter center dispersal is used,which is conducive to reducing the difference of the fuel dispersal velocity at different positions.
