摘要: 对布撒网系统纵向展开问题进行了研究。研究采用二维运动模型简化,运用多体系统动力学理论和集中质量法,建立了布撒网纵向展开过程的多刚体动力学模型。运用Kane方法建立系统动力学方程,运用数值方法分析和计算了该动力学方程,给出了布撒网纵向展开的动力学过程。得到了火箭和网上各点位置和受力的时程曲线,以及火箭和网的飞行轨迹。计算结果与模拟布撒网展开实验结果吻合。

Abstract: The lengthwise deployment of a net towed by a rocket is studied. The problem is simplified as two-dimensional motion, and a multi-rigid-body dynamic model is built. The dynamics equation of the multi-body system is built using Kane's method and is derived with numerical computation method. The calculated results which contain the trajectory and tension of the rocket-towed net system are in agreement with the simulation results.
