基于虚拟现实的防空导弹杀伤效果仿真

为真实再现防空导弹遭遇目标时的情景,模拟引信起爆战斗部及其配合情况,表现导弹战斗部破片对目标的覆盖程度,显示破片命中目标的位置和毁伤情况,统计命中目标的破片数,在建立弹目运动、引战配合、目标易损性、破片弹道飞散、命中目标的破片数目等数学模型的基础上,应用场景生成、实体模型建立、环境集成、碰撞检测等技术,创建出接近真实试验环境的三维虚拟世界,实现了导弹对目标杀伤效果的虚拟仿真,从而改进了导弹试验结果分析和评定方法,提高了工作效率.

Simulation of Killing Effect of Air-defense Missile Based on Virtual Reality

Based on the mathematic models of the motion between air - defense missile and target, the matching of fuze with warhead, the target vulnerability, the missile fragment trajectory, and the hit fragments number, and on the technologies of environment generation, entity modeling, environment integration and collision detection, this paper implements a three - dimensional virtual environment near to the real test situation, which could reproduce the scene when missile encountering target, simulate the action and matching of fuze with warhead, show the target coverage with warhead fragments, display the position of fragments and the damage of target, and provide the hit fragments statistics. As a result, it realizes the virtual reality simulation for killing effect of the air - defense missile, and will improve the analysis and evaluation of the missile test results, and finally raise the working efficiency.
