为研究子弹落点散布规律, 对其影响因素和子弹外弹道计算方法进行分析.将抛撒高度偏差和阻力系数偏差用Monte Carlo方法处理后建立子弹外弹道抛撒模型, 利用Matlab软件进行数值仿真并绘制子弹分布散点图, 分析子弹散布随抛撒高度变化的规律;进行子弹动态抛撒试验, 将得到的实测图与仿真散点图对比, 验证了模型的合理性, 为离心式惯性抛撒原理和子弹散布分析提供理论参考.%In order to study the lawof bullet placement, the influencing factors and the calculation method of bullet external ballistics were analyzed. The height deviation and drag coefficient deviation were processed by Monte Carlo method to establish the bullet external ballistic throwing model. The Matlab software was used for numerical simulation and the bullet distribution scatter plot was drawn to analyze the lawof bullet dispersion with the height of the throwing. The bullet dynamic scattering test was carried out, and the obtained sets of measured maps were compared with the simulated scatter plots to verify the rationality of the model, and provide a theoretical reference for the centrifugal inertial throwing principle and the bullet dispersion analysis.
