为了计算战斗部破片命中点参数,在考虑速度衰减条件下,利用射击线法提出了一种通过一次遍历求解所有破片命中点参数的计算模型.通过分析,获得解的3种存在条件,分别对应于单枚破片与目标面元的3种运动关系.以钢球破片为例,定量讨论了弹目交会参数和速度衰减系数对命中点参数的影响.结果表明,目标的运动速度和静态破片初速对命中点参数的影响比较大,导弹运动速度对命中点参数的影响较小.

To calculate hitting point parameters of fragment accurately, a calculation model was proposed to get all hitting point parameters by numerating fragments only once. In this model, the shot-line technique, which took the velocity fade into account, was adopted to describe the fragment trace. Three kinds of existence conditions of solutions, which were corresponding to three kinds of motion relationship between single fragment and target face, were obtained by analyzing the model. Taking the steel fragment for an example, the effects of warhead/target encounter parameters and fading coefficient of fragments velocity on hitting point parameters were discussed quantificationally. Results show that,the hitting point parameters are sensitive to target velocity and static fragments velocity, but insensitive to missile velocity.
