基于蒙特卡罗法的枪弹弹头外弹道散布特性分析

针对枪弹落点较为随机的问题,对随机因素影响下的枪弹弹头外弹道散布特性分析方法进行研究.分析各随机因素产生的原因,确定各随机因素的概率分布模型,并利用Matlab软件产生符合各随机因素概率分布的随机数;应用C++语言编制随机外弹道计算程序,通过循环调用各因素随机数进行外弹道虚拟试验,模拟得出多组弹丸落点坐标;利用经典的统计试验法——蒙特卡罗法分析得出弹丸落点的统计特性,结果与试验数据基本吻合.分析结果表明,该研究成果可以为减小弹头落点散布、提高射击精度提供技术支撑.

Analysis of External Trajectory Dispersion Characteristics of Bullets Based on Monte Carlo Method

Aiming at the problem of the random placement of bullets, analyzes the method of analyzing the trajectory of bullet trajectory under the influence of stochastic factors.The causes of random factors were analyzed, and the probability distribution model of each random factor was determined.Use Matlab software to generate random number which meet requirements of each random factors model. Use C++ language to compile random external trajectory calculation program, carry out external virtual simulation by recycle calling factor random number, and simulate multi groups of bullet placement coordinates. Use typical calculation test method (Monte Carlo) to analyze calculation feature of bullet placement, and the results meets the test data. The analysis results show that the research results can provide technical support for reducing the placement of warheads and improving the shooting accuracy.
