摘要
研究末敏弹运动的实时跟踪与控制问题。因为末敏弹在运动过程中要打开减速伞与减旋翼,外弹道运动规律与常规制导导弹有很大的不同,因此构建末敏弹可视化仿真试验平台有一定的难度。根据典型末敏弹的结构特点及减速减旋段的运动特性,提出了一种利用Simulink/Matlab和VR技术对其进行可视化仿真研究的方法。仿真结果表明,利用上述方法建立的可视化仿真系统模型准确,三维视景逼真,并具有良好的实时性和可控性,很好地再现了末敏弹减速减旋段运动过程,可以为末敏弹的研制和战术训练提供技术支持。
Study on the visualization of tracking and control of Terminal-sensitiye Projectile in motion. Because terminal-sensitive projectile will open its parachute and wing during the movement, and its law of motion of the exter- nal ballistics are very different from conventional guided missiles, so there are some difficulties to construct its visual simulation test platform. According to the structure characteristics of typical terminal-sensitive projectile and move- ment characteristics of the deceleration and rotary stage, this paper presented a method of visual simulation using Sim- ulink/Matlab and VR technology. The simulation results have shown that the model of visual simulation system built by using this method is accurate, the scene is vivid, and the system has good characteristics of real-time and control- lability. The motion process o：f the stage of deceleration and rotary is reproduced well, and the result can provide some technical support for development and tactical training of terminal-sensitive projectile.
