摘要
研究在轨捕获技术的问题中,空间绳系飞网作为一种柔性捕获手段在航天工程中具有广泛的应用前景,进行仿真成为必不可少的研究手段。首先建立了系绳的简化模型,讨论其短距离捕获阶段的释放方式。在此基础上,运用弹簧-质点模型对飞网进行建模,分析了飞网飞行过程中的受力情况,并采用Verlet数值积分方法对模型进行仿真计算,最后对飞网捕获目标进行了碰撞检测。仿真结果正确显示了捕获阶段飞网的运动过程,实时性良好,对空间飞网的设计研究具有一定的意义。
As a flexible on - orbit capture mode,space tether net has great application foreground on space engineering, so modeling and simulation become an important way to study the characteristic of this system.At first,simplified model of tether was established,and its developing method suitable for short distance capturing operation was discussed.Base on the model of tether,spring mass model was applied for net,and its mechanic condition during flying process was analyzed,then Verlet numerical integration method was applied in calculating the model.At last, collision response was processed when net captured object.Simulation results with good real - time characteristic reveal motion process of space net during capture phase properly.This simulation method will play an important role in the study and design of space tether net.
