摘要在现代战场上，坦克、战车等集群目标在战场上发挥着重要作用。于是，就必须研 发打击这些集群目标的武器。而子母弹，具有大纵深打击敌后方目标以及大面积封锁和 杀伤能力，越来越受到重视。81015

本文以中心炸管式子母弹内弹道抛撒为研究对象，认真分析其内弹道过程，整个过 程根据子弹的运动情况分为定容过程和增容过程，其内弹道物理模型需分阶段建立。根 据经典内弹道理论中的相关知识，对整个过程作出合理的假设，并建立中心炸管子母弹 抛撒内弹道过程的数学模型。认真分析数学模型后，选择合适的数值计算方法——龙格 库塔法进行计算，利用数值仿真软件编写程序得到子弹抛撒速度、弹后空间距离、以及 加速度曲线。在分析对子弹抛撒速度产生影响的因素时，采用正交试验法，设计正交试 验，详细分析抛撒药装药质量、中心炸管炸裂压力、中心管燃烧室容积这三个因素对子 弹抛撒速度的影响程度。

Title Numerical simulation of the interior ballistic of the central blast tube cluster munition

Abstract In the modern battlefield,it is the integrated targets such as tanks and chariots play a significant role。Therefore,it is important to research and develop a kind of weapon which is directed against these integrated targets。Shrapnel,which is famous famous for its ability to blockade and destruct extensively,receives more and more attention。

This article select central tube bursting-type as the study object,and analyse its its working process。According to the motion of the bullet,the whole working process can be pided into two stages:constant volume process and increasing volume process。On the basis of the classic interior ballistic theory,reasonable hypotheses are put forward,and the theoretical model in the throwing procedure of central tube bursting type has been established。And then,this article chooses reasonable numerical calculation method-- Runge-Kutta,and uses simulation method to acquire the ballistic performance curves of this system。

Through the analysis of the orthogonal experiment,the influence of charge weight of prepellant,the allowable pressure of central tube and the volume of drug room on the velocity of submunitions are got。

Keywords the dispersing of cluster munition, the central tube bursting-type, interior ballistic process, dispersing velocity, orthogonal experiment
