摘　　要：导电纤维子母弹是一类以电力系统为攻击目标的软杀伤弹药,其导电纤维子弹药常见的外形为圆柱形,不带减速稳定装置,在飞行过程中攻角变化范围较大.当子弹药运动出现不确定或者过大的姿态角时,弹道计算方法中应用的传统的欧拉运动学方程会出现奇异性.为了解决奇异性的问题,运用四元数法建立了弹道计算模型,并将计算结果与实验数据进行了对比.分析了初始弹道倾角,母弹开舱高度,子弹药抛撒速度等因素对子弹药最优飞行时间的影响,同时给出了指定初始条件下子弹药的失效时间.Submunition made of conductive fiber was a kind of soft kill munition for attacking electrical power infrastructure. The shape of the submunition usually looked like a circular cylinder without any deceleration stabilized device. The angle of attack had a wide range during the flight. When uncertain or excessive attitude angle occurred, conventional Eulerian equations of motion usually applied in ballistic calculation showed singularity. To solve this problem, calculation model of ballistics was established based on quaternion, the calculated results and experimental data were compared. Some influence factors including initial ballistic angle, cabin open height of the carrier and dispersed velocity of submunition are considered. Impact of these factors on optimal time of flight is analyzed. Also, the failure time of submunition is provided in certain initial conditions.
