摘　　要：根据全电推进卫星的星体布局约束,文章提出了多自由度可展开式矢量调节机构构型设计,综合考虑整星需要完成的转移轨道变轨、同步轨道南北位保、东西位保、动量卸载等功能,细化出各个指向位置和范围需求,分析出可展开矢量调节机构的四自由度需求,并根据全电推进指向任务的需求,分析出可展开矢量调节机构各关节布置可达域情况,最后,通过建立数学模型进行指向范围复核和确认。经亚太6E卫星验证,结果表明:构型设计合理,可以为多功能矢量调节机构的设计提供参考。Based on the structural layout constraints of an fully electric propulsion satellite,a multi-degree-of-freedom deployable vector adjustment mechanism configuration design is proposed in this paper.It comprehensively considers the functions that the satellite needs to perform,such as transfer orbit maneuvers,north-south position preservation in geostationary orbit,east-west position preservation,momentum unloading,etc.,refines the pointing position and range requirements for each direction,analyzes the four-degree-of-freedom requirements of the deployable vector adjustment mechanism,and evaluates the reachable range of each joint arrangement in the mechanism according to the demands of the fully-electric propulsion pointing mission.Finally,by establishing a mathematical model,the pointing range is reviewed and verified.Validation through APSTAR-6E satellite demonstrates that the configuration design is reasonable and can provide reference for the design of multi-functional vector adjustment mechanisms.
