基于XSim仿真平台的榴弹炮建模与弹道仿真

Howitzer Modeling and Trajectory Simulation Based on XSimStudio Simulation Platform

榴弹炮仿真是陆军装备仿真国产化的未来研究方向之一,针对如何建立榴弹炮的实体模型以及设计榴弹炮的弹道解算模型是仿真模拟系统研究中非常重要的一部分,通过组件化建模的方式设计榴弹炮的实体仿真模型,建立外弹道动力学微分方程组,基于四阶龙格-库塔方法求解射击诸元,并结合射表真值设计弹道解算模型,针对实际环境中扰动量过多的问题,将仿真的扰动量简化成高低向和方位向两个扰动变量,再有效逼近射表的公算偏差。构建具体作战场景,将构建的榴弹炮模型和火力范围在设计的场景下进行模拟仿真,去检验模型仿真的效果,结果表明,提出的榴弹炮模型和弹道模型在榴弹炮训练仿真方面表现出较高的性能。

Howitzer simulation is one of the future research directions for the localization of army equipment simulation.How to establish the physical model of howitzer and design the trajectory calculation model of howitzer is a very important part of the simulation system research.The physical simulation of howitzer is designed by means of component modeling.Differential equations of external ballistic dynamics is established,the firing data are solved based on the fourth-order Runge-Kutta method,and the trajectory calculation model based on the true value of the shooting table is designed,aiming at excessive disturbances in the actual environment,the author simplifies the simulated disturbances into two disturbance variables in the elevation and the azimuth direction,and effectively approximates the probable error of the firing table.A specific combat scenario is constructed to simulate the built howitzer model and firepower range in the designed scenario to test the effects of the model simulation.The results show that the proposed howitzer model and ballistic model perform well in the simulation of howitzer training performance.
