摘　　要：文中旨在提出可工程应用的中心起爆聚焦离散杆战斗部杆条初始飞散姿态控制模型,通过典型中心起爆离散杆战斗部地面试验现象,给出中心起爆聚焦离散杆战斗部杆条微元的速度计算模型,并对杆条两端的速度分解,推导了杆条旋转到与战斗部轴线垂直时的飞行距离计算模型,然后与试验值进行了对比分析,验证了该计算模型的可行性,为中心起爆离散杆战斗部设计提供参考。The goal of this paper is to put forward the origin dispersing gesture model of the rod in the discontinuous-rod warhead ignited at the center to be used for the engineering. According to the ground experiment result of the typical focusing discontinuous-rod warhead ignited at the center of the warhead, the infinitesimal element origin-velocity model of this typical focusing discontinuous-rod warhead is put forward. After then, based on the velocity model, the velocities at the both ends of rod are resolute and the flying distance model is introduced when the axis of the dispersed rod rotates to be perpendicular with the axis of the warhead. The calculating results are contrasted with the value from other ground experiment to validate the feasibility of the model in the engineering. The content in this paper is referred for the design of the focusing discontinuous-rod warhead ignited at the center.
