基于正交试验设计的导弹落点散布仿真分析

Simulation and Analysis of the Dispersion of a Ship-based Missile Falling on Deck After Failed Ignition on Orthogonal Experiment

舰载导弹垂直弹射升空后如果未能正常点火则对作战中的舰艇安全造成严重威胁,考虑舰艇的行进速度和摇摆运动对舰载导弹离轨参数的影响,首先对舰载导弹空中未点火运动进行了动力学建模,然后通过应用正交实验设计方法,摸清试验参数对导弹运动的影响情况,确定出参数影响的主次顺序,为工程上解决空中未点火导弹砸舰问题提供了可靠的依据。

The warship would be subjected to serious threat if a ship-based vertical missile had a failed ignition. Firstly, the matlab model of a ship-based missile falling on deck after failed ignition was established considering the speed and swings of the warship. Then the orthogonal experiment method was used to analyse the influence of kinematic parameters. The primary and secondary sequence of the influence of the different kinematic parameters was found. The result gives credible basis resolving a dash against the body of a ship-based missile after failed ignition.
