摘要
文中基于恢复系数动态接触理论,建立了火箭武器发射过程中弹管动态接触碰撞的动力学模型。通过发射仿真分析,获得了火箭弹在高低压发射系统中的内弹道变化规律,分析了火箭弹与定向器的接触刚度、耳轴扭转刚度、尾喷管推力偏心等因素对俯仰角速度的影响特性,所得结论为火箭武器高低压发射系统的进一步相关研究奠定了基础。
Based on dynamic contact theory about recovery quotients, the dynamic contact model of rocket projectile＇s movement in direction pipe was established. In this paper, movement principle of rocket in direction pipe was got by dynamic simulation, and effect characteristic considering contact stiffness, detent force and nozzle thrust misalignment about pitching angle velocity was analysis. All the study set foundation for further study of high-low pressure launch system.
