导弹运动方程求解策略研究

Strategy Study on Missile Motion Equations

研究导弹求解优化问题,针对提高弹道仿真程序的适用性,研究了导弹运动方程的自动求解问题。鉴于目前大多数弹道仿真程序或软件都是针对特定对象编制的,缺乏通用性和移植性,根据导弹运动方程特点,提出一种关于非线性方程组的自适应求解策略。算法以4类参数集描述导弹运动方程,通过自动排列方程求解顺序并对其求解,实现了导弹运动方程求解的自动化。仿真结果表明,改进方法可较好适应于各类弹道仿真计算,对提高弹道程序通用性具有重要意义。

In order to improve the applicability of trajectory simulation program,this paper studied the automatic calculation methods of missile motion equations.In view of most trajectory simulation programs or softwares prepared for a specific object currently and lack of versatility and portability,the author proposed a new adaptive automatic strategy of nonlinear equation sets based on missile motion.The algorithm depicts the missile motion equation in 4 types parameter sets and calculates the solution by auto arrange the solving order of equations,which realizes the automatic calculation of missile motion equations.Primary application shows that the method can be used for various types of ballistic simulation calculations and of great significance to the improvement of ballistic procedures versatility.
