空間機(jī)構(gòu)地面重力補(bǔ)償設(shè)備跟蹤研究

An investigation into gravity compensation equipment for space mechanisms

摘要: 由于飛行軌道上或其他星球上的重力環(huán)境與地球表面的重力環(huán)境差異很大，而在飛行前必須在地面確認(rèn)機(jī)構(gòu)在空間的性能和可靠性，這就要求在地面實(shí)現(xiàn)對(duì)空間機(jī)構(gòu)實(shí)際工作時(shí)的空間重力環(huán)境的模擬，于是提出了對(duì)地面重力補(bǔ)償設(shè)備的需求。文章對(duì)實(shí)現(xiàn)重力補(bǔ)償?shù)囊话阈问竭M(jìn)行了介紹和分析，舉例說明了常用的地面重力補(bǔ)償設(shè)備的原理，總結(jié)歸納了地面重力補(bǔ)償設(shè)備的設(shè)計(jì)原則和工程實(shí)施經(jīng)驗(yàn)。

Abstract: 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.
