摘要
绳系卫星系统部署阶段末时刻状态决定着其编队飞行的初始状态,为了研究不同因素对绳系卫星系统部署阶段运动的影响,建立了一种简单的平面哑铃模型,将系绳视作有阻尼的弹簧,两个卫星视作刚体,考虑重力梯度力矩。通过仿真,发现系绳释放的速度和副星推力是影响绳系卫星系统部署阶段稳定性的主要因素。
The final state of the deployment phase of the tethered satellite system determines the initial state of formation flight.In order to study the influence of different factors on the deployment phase of tethered satellite system,this paper establishes a simple planar dumbbell model.The model considers the tether as damped spring and two satellites as rigid bodies,at the same time,considering gravity gradient moments.It is found that the speed of tether release and the thrust of sub-star are main factors affecting the stability of the deployment phase of the tethered satellite system by simulation.
