摘要
针对反辐射导弹战斗部毁伤效果影响因素多,为提高毁伤效率,需要分析其中主次因素。利用有限元仿真方法,仿真战斗部爆炸过程,获取战斗部破片静态散射角。根据动态散射角计算公式计算动态散射角,结合反辐射战斗部与相控阵天线间的弹目交汇分析,得出破片散射密度。并根据战斗部影响因素,得到弹目交汇面积计算模型。依据模型和正交试验方法,编试验方案,获得各因素不同值条件下战斗部的毁伤效果数据。最后采用极差分析方法得到各因素的重要度以及主要因素和次要因素,对提高反辐射导弹战斗部毁伤效果有一定指导意义。
Due to many factors affecting anti - radiation warhead damage effect, the key factors should be tound. Base on FEM simulation, the warhead＇s explosion is simulated, and the static scattering angle of warhead is obtained. By using formula and analysis of intersection of missile and target, the dynamic scattering angle, fragments scattered density and the model of intersection of missile and target are obtained. On the basis of the model and the method of orthogonal test, the damage data are ggt from anti - radiation warhead orthogonal test. At last, the key factors and secondary factors are obtained by the method of range analysis. This result has some significance for enhancing the damage effect of Anti - radiation Missile Warhead.
