摘要:
为研究航空末敏子母弹子弹的地面散布问题,基于欧拉方法建立了航空末敏子母弹的母弹飞行阶段六自由度数学模型,基于拉格朗日多刚体建模方法建立了子弹减速阶段以及稳态扫描阶段的动力学模型,对衔接段做合理假设后,得到了航空末敏弹的全弹道模型; 分析了载机水平投弹速度和抛撒速度对子弹地面散布情况的影响。仿真结果表明:末敏子弹散布x、z轴方向落点间距与抛撒速度大小成正比; 末敏子弹散布x轴方向的落点间距与载机的水平投弹速度大小成正比,投弹速度对z轴方向的落点间距基本没有影响。
Abstract:
To research the submunition ground dispersion of aviation terminal-sensitive cluster warhead(ATSCW),the 6-DOF mathematics model of ATSCW at the flight stage was established based on Euler method,and the dynamic model of the deceleration stage of warhead and stable scanning stage was developed based on Lagrange multi-rigid modeling method. A reasonable assumption was made for linkage stage,and the whole ballistic model of ATSCW was obtained. The influence of scattering velocity and the level dropping speed on the dispersion was studied. The simulation result shows that landing distances in x-axis and z-axis are directly proportional to the scattering velocity,and the x-axis landing distance is directly proportional to the level dropping speed,and the dropping speed has litter influence on x-axis landing distance.
