对末敏弹这一全新反坦克武器在减速运动和稳态扫描段的运动特性进行了仔细的研究。恰当地引入了降落伞的附加质量和附加惯性矩，完整地分析了伞体和弹体所受的外力和外力矩，建立了由伞体和弹体组成的末敏弹系统二体运动模型。编制了完整的计算程序。给出了末敏弹扫描角速度、扫描角和扫描曲线随时间的变化，以及扫描覆盖区随高度的变化。计算结果与试验结果有很好的一致性。该模型可进一步用于末敏弹系统的弹道修正、参数优化和弹道模拟。
The kinematic characteristics of this new antitank weapon, the slow-motion and steady-state scanning, were carefully studied. The additional mass and additional moment of inertia of the parachute are introduced properly. The external force and external moment of the parachute and the projectile are analyzed. The two - body motion model of the end - sensitive projectile system is established. A complete calculation program has been prepared. The change of scanning angular velocity, scanning angle and scanning curve with the time and the change of scanning coverage area with height are given. The calculated results are in good agreement with the experimental results. The model can be further used for trajectory correction, parameter optimization and trajectory simulation of the end-sensitive projectile system.
