基于SIMULINK的弹丸自然破片运动模型仿真研究

RESEARCH ON SIMULATION MODEL OF NATURAL FRAGMENT MOVEMENT OF AMMUNITION BASED ON SIMULINK

为了研究实际空气中自然破片的运动规律,建立了直角坐标系下破片质心运动模型,并建立SIMULINK仿真模型对破片的运动微分方程组进行仿真求解,得到了破片的运动轨迹、飞行的水平距离、落地时的动能,以及破片随其初始飞行角度变化的规律。研究结果表明,基于SIMULINK对弹丸破片运动规律进行研究,可以获得直观、形象、准确的仿真计算结果,为进一步研究破片的杀伤、设防、防护打下了基础。

In order to study the movement law of natural fragment in air, the movement model of centroid of fragment was established in the cartesian coordinate system, and the movement differential equa tions of fragment were simulated based on SIMULINK simulation model. The movement trajectory, the flight horizontal distance, and the kinetic energy of fragment were obtained through simulation calculation, and the change laws between those factors and initial flight angle were researched. The research results showed that the simulation calculation could be reached directly, visually and precisely by studying the movement law of natural fragment based on SIMULINK. These research results provided the foundation for the further researching damage, fortification and protection of fragment.
