| 摘 要： | 在已有的研究结果的基础上，对空间系绳在回收容器回中的应用，作了进一步分析，包括从回收容器离开空间站至回收容器从系绳上脱落的系绳伸展运动，（２）从系绳脱落的回收容器的返回运动，（３）释放容器后的系绳的收回运动。对回收容器的动态释放，除了两阶段指数型伸展程序外，还提出了另外两种导致系绳后摆的方式。对静态释放与动态释放，不仅对系绳长度，而且对系绳张力作了计算与分析。为了系绳收回过程的稳定，不仅要施加张力

| Abstract: | The use of tethers for re-entry of space capsules has been analyzed in this paper. The analysis covers (1) deployment of the tether, (2) re-entry of the capsule and (3) retrieval of the tether after release of the capsule. In addition to static release, swing release is also considered. For swing release, three kinds of deployment procedures are presented. Length of tethers used for re-entry of space capsules and tension in tethers before release are taken into account. To stabilize the tether during retrieval,tension control is used, and certain mass has to be left on the lower end of the tether after release of the capsule. |
