多管火箭炮发射中的变结构问题

The Variable Structure Problem of the Multitube Rocket Gun Systems

该文对多管火箭炮系统中的变结构问题 (包括变自由度和变拓扑结构 ) ,提出了关于变结构系统不变化的策略 ,将变结构看作稳态结构。对这个“虚拟稳态结构系统”的动力学建模和仿真采用“分路”法 ,高效地实现了多管火箭炮各发射阶段的自动切换。

The problem of variable structure of the multitube rocket gun systems includes the variable degree of freedom and the variable topology. As for the problem, the strategy of how to translate one variable structure into an unvarying structure is proposed. By use of this strategy, an unsteady structure can be virtual regarded as a steady structure. For the dynamics modeling and simulation of the virtual steady structure, the method of dividing lane is adopted.The automatic exchange of launching stages of multitube rocket gun is fulfilled efficiently.
