【摘要】 在现代战争远距离精确打击的背景下,提高武器精度和弹药能量的利用率成为武器发展的两大趋势。在这种背景和趋势下,子母弹应运而生,它是提高常规战斗部有效利用率和毁伤效果的重要途径,是未来高技术局部战争中必不可少的一种作战武器。子弹落点散布是火力运用的基础,本文主要内容是研究子母弹的散布特性,为子母弹设计和火力运用提供辅助决策信息,以提高武器作战效能。以分析子弹落点散布特性为目的,本文展开了一系列研究工作。首先,针对子弹为刚性尾翼无控子弹、采用侧向抛撒方式的子母弹,建立了在发射坐标系下的子母弹飞行动力学模型,给出了一种求解同射程条件下具有不同特性弹道的方法,并计算了三条具有不同特性的母弹弹道,为子弹落点散布分析提供了基础;针对散布形状为椭圆环的情况,提出了完整的散布特性参数,给出了散布特征范围的具体计算方法及均匀性评定方法,为子弹落点散布分析提供了依据。然后,利用标准弹道仿真产生子弹落点的方法对单层子弹落点散布进行了分析,利用基于侧向抛撒方式的子弹落点抽样方法对子弹落点散布均匀性进行了分析。最后,介绍了一种稳健设计方法――Taguchi方法,并针对跑道目标,利用该方法对影响毁伤效果指标的因素进行参数优化与分析,得到了有益的结论。论文对子弹落点散布特性进行了比较全面深入的研究,论文所做工作对于提高子母弹的作战效能具有很好的参考价值和应用价值。更多还原

【Abstract】 On the background of long distance precious attack in the modern war today, it has become two directions for development of weapon that improving precision and making better use of ammo energy. Cluster warhead emerges as the times require. Using cluster warhead is an important way to make good use of general combat warhead and improve destroy efficiency, so it is the absolutely necessary combat weapon in the future high technology local war. As cluster warhead submunition dispersion is the basis of using weapon, the main content of this paper is to study the distribute characteristic of cluster warhead, and it can provide some assistant information for designing and using cluster warhead to improve fighting efficiency.This paper carries out a series of work aiming at analyzing the distribute characteristic of cluster warhead impact point. It first establishes a flight dynamic model of cluster warhead in the launch coordinate system, develops a method of calculating different characteristic ballistic trajectory which has the same shot distance, and calculates three different characteristic ballistic trajectories, which provides the basis of analyzing the distribute characteristic of cluster warhead impact point; presents a group of dispersion parameter when the shape of submunition dispersion is a elliptic circle, develops a evaluation method of calculating dispersion range and submunition uniformity for cluster warhead submunition, which provides the basis of analyzing the distribute characteristic of cluster warhead impact point. Then, this paper analyzes the dispersion characteristic of a single layer of submunition by the ballistic simulating calculation, and analyzes the submunition uniformity by using sample method to produce impact point of submunition. Last, this paper introduces a kind of robust design method—Taguchi method, by which to optimize and analyze the parameter which affect the destroy efficiency to airport runway, and gets some helpful conclusion.This paper makes a relatively deeply study of cluster warhead submunition dispersion, and has a good reference and upper application value to improve the fighting efficiency.更多还原
