空间机构地面重力补偿设备跟踪研究

摘要

由于飞行轨道上或其他星球上的重力环境与地球表面的重力环境差异很大,而在飞行前必须在地面确认机构在空间的性能和可靠性,这就要求在地面实现对空间机构实际工作时的空间重力环境的模拟,于是提出了对地面重力补偿设备的需求.文章对实现重力补偿的一般形式进行了介绍和分析,举例说明了常用的地面重力补偿设备的原理,总结归纳了地面重力补偿设备的设计原则和工程实施经验.%Because the gravity on the surface of the earth is quite different from that on the flight orbit or on the surface of other planets, the performance and the reliability of a space mechanism should be tested and verified on the ground before launch. The gravity environment for a practical working state should be simulated correctly in ground tests for space mechanisms; therefore, it is necessary to have a ground gravity compensation equipment. This paper discusses the basic types of this kind of equipment, and the principles of commonly-used equipment with examples. The related practical engineering experience is reviewed.
