非标准气象条件下火炮外弹道仿真

Gun Exterior Ballistics Simulation Analysis under Nonstandard Meteorological Conditions

针对目前弹道仿真均建立在标准气象条件下,无法反映弹道真实情况的问题,以非标准条件弹道模型为基础在非标准气象条件下改进了气温气压模型并建立了风场模型。应用Matlab/Simulink仿真工具构建对应的仿真模型;最后对某型火炮进行仿真验证。并通过对仿真结果分析得出各种气象条件对弹道诸元的影响规律,揭示了气象因素与射击误差的关系,为新型火炮非标准气象条件下弹道研究、火炮模拟器弹道仿真开发以及部队实弹射击提供了参考依据。

Because the gun exterior ballistics simulation under standard meteorological conditions cannot reflect the real situ- ation of ballistics, the paper improves the temperature and air pressure model and establishes a wind field model on the basis of the ballistics model under nonstandard meteorological conditions. It constructs a simulation model of the gun exterior bal- listics under nonstandard meteorological conditions by Matlab/Simulink. At last, it completes the simulation verification for a certain gun. Through analyzing the simulation results, it gains the law of various meteorological conditions influence on bal- listics parameters, reveals the relationship between meteorological factors and firing errors and provides references for the ballistics study of the new type gun, the ballistics simulation of gun simulator and the gunshot of military units.
