多星分离速度设计

针对多量分离过程对星间最小间距的要求，运用Ｈｉｌｌ方程，对其相对运动进行了分析，提出了一种分离速度设计方法，讨论了最小间距最大化问题，并给出了最小间距最大的等 条件，最后，针对一箭五星情况进行了仿真计算，结果表明，该方法简单、有效，最小间距的最大值明显大于设计要求值，这就分离速度的设计、选择提供了很大的余地。

Velocity Design of Separating Multi-Satellite

Considering the construction of the minimal distance among satellites (including the vehicle) during separating course, the paper adopts Hill equation to analyze their relative motion. It brings up one method of velocity design, discusses how to maximize the minimal distance, and gives an equal condition. It offers the case of one vehicle with five satellites, and the result indicates that the method is handy and efficient, and that the maximum of the minimal distance is obviously larger than what is needed. This provides more prodigious room for the design and selection of separation velocity.
