集束子弹药落点分布关键影响因素分析

为研究子弹药不同抛撒初始条件对子弹药抛撒散布特性的影响规律，以某种集束弹药为研究对象，考虑 随机因素对子弹药抛撒散布的影响，建立子弹药抛撒运动学模型。通过仿真分析得到子弹药抛撒运动规律和落点散 布规律，选取母弹抛撒高度、母弹存速、母弹转速和母弹俯仰角4 种子弹药抛撒关键因素，运用数值仿真的方法分 析单一因素不同初始条件对子弹药落点散布的影响，并总结4 种关键因素的影响规律。

Analysis on Key Influence Factors of Cluster Sub-munitions Drop Point Distribution

In order to study on the influence regularities that the different dispersion initial conditions of the sub-munitions make on the dispersion distribution characteristics, this paper takes a certain cluster munitions as the research object, and the sub-munitions dispersion kinematic model is established with considering the influence that the random parameters make on the dispersion distribution. The dispersion motion regularity and the drop point distribution regularity of the sub-munitions are obtained by simulation. Selecting 4 key factors making influence on the dispersion as the dispersion height, the velocity, rotation angular velocity and pitch angle of the mother bomb, the influences exerted on the drop point distribution of sub-munitions by different initial conditions of the single factor are analyzed with the numerical simulation method. At last the influence regularities of 4 key factors are summarized.
