摘要
弹道数值仿真是研究弹道特性的重要方法,文中运用弹道理论分析弹道修正火箭弹的弹道特点,利用Matlab/Simulink平台对弹道修正火箭弹的模块化建模方法进行了研究。依据功能模块划分的基本建模方案,确立了以弹体运动、导航参数测量和导引控制为主要模块的建模方案,给出了实际的建模结果。最后,设置仿真初始条件,利用所建弹道模型进行了仿真,结果很好的符合了火箭弹的弹道特点和飞行规律,验证了弹道模型的可行性和有效性。
The trajectory numerical computation was the significant method of trajectory characteristics research.In this paper,the ballistic characteristics of trajectory correction rocket were analyzed by using ballistic theory,and the modular modeling method of trajectory correction rocket was studied by using Matlab/Simulink platform.Based on the basic modeling scheme of the function module,the modeling scheme was established,which was based on the measurement of projectile motion,navigation parameters and quidance control,and the actual modeling results were given.Finally,the initial conditions of the simulation were set up and the trajectory model was used for simulation.The results showed that the model could be well correspond with the actual rocket trajectory characteristics and the flight law.The model was verified to be reasonable and feasible.
