DETERMINING THE POSITION OF THE FIRST CONTACT POINTS FOR THE SPACE VEHICLES WITH ANDROGYNOUS PERIPHERAL DOCKING MECHANISM

对周边式对接机构的航天器进行了研究，在对接捕获过程中首次接触撞击点的确定问题。文中建立了三类可能接触区域的空间解析描述关系式，根据空间“点”投影的不变性原理，给出了确定可能接触点的数学方程，使原问题由三维空间问题简化为二维平面问题，其难度和复杂性都大大简化。最后，文中还给出了多组算例。

In this paper,the problem about the position of the first contact points for the space vehicles with androgynous peripheral docking mechanism is analyzed.First,the space analytic equation for three kinds of contact domain possible is establisehed about the above mechanism.then,on the basis of the principle of 'point' projection is unchanged,the space analytic equation is reduced to two dimension.The diffculty and complexity to determine the position of the contact points is greatly simplified.Finally,many examples are given.
