摘要: 交會(huì)對接設(shè)備是實(shí)現(xiàn)飛行器交會(huì)對接的重要部件。它的安裝精度直接影響交會(huì)對接任務(wù)的成敗。為了研究太空環(huán)境下飛行器艙體壓差對交會(huì)對接設(shè)備安裝姿態(tài)的影響，文章根據(jù)太空環(huán)境飛行器所受壓差情況，設(shè)計(jì)了地面仿太空環(huán)境試驗(yàn)，對某型號(hào)飛行器的交會(huì)對接設(shè)備及艙體基準(zhǔn)進(jìn)行了姿態(tài)測量，分析了由于艙體內(nèi)外壓差的影響而造成的設(shè)備姿態(tài)變化，并根據(jù)試驗(yàn)結(jié)果分析研究出一種新的地面總裝精測工藝方案。Abstract: Rendezvous and docking device is important for realizing spacecraft docking, and its installation precision counts much for the docking mission. To investigate the differential pressure on RVD device in its attitude, the alignment test of the device and the cabin was carried out in a simulated space environment. The attitude changes of the device under different pressure conditions are obtained. Based on the results, a new approach for ground-based assembly is proposed.
