空间交会V-bar和R-bar的仿真分析

A Study of Approach Trajectory for Space Rendezvous

V-bar和R-bar逼近方式是近来发展起来的两种很重要的空间交会对接接近段的逼近方式,文中主要从轨道动力学方面研究这两种逼近方式,推导得到V-bar最一般的相对运动规律,并进行了仿真分析;采用拟牛顿法求解得到时间最省R-bar相对运动轨迹和燃料最省R-bar相对运动轨迹。文中研究内容对于解决空间交会对接接近段逼近问题具有良好的工程实际应用和理论意义。

V-bar and R-bar approach maneuvers are two important methods for approaching the target for rendezvous and docking. This paper focuses on these approaching methods. Firstly, relation motion of V-bar approach is achieved based on the C-W equations and some important rules are obtained. Secondly, the time-optimal R-bar relation trajectory and fuel-optimal R-bar relation trajectory are got by using the BFGS method. At last, the relation motion of V-bar and R-bar has been simulated numerically based on this methodology. The simulation results show that the studies presented in this paper are of practical engineering value and theory significance.
