摘　　要：针对亚太6E卫星结构承载大、布局空间紧凑、主卫星(主星)和推进舱在轨可分离的特殊要求。设计了一种新型的板杆结合式卫星主结构,以箱板式结构为基础,杆系结构为主承力件,板杆混合式结构既提供了开敞高效便利的布局和安装空间,也解决了卫星承载难题;设计了内置贮箱,外挂两个燃箱的全新推进舱结构,3个贮箱(即一个氧箱和两个燃箱)并联布局承载,能够降低卫星质心,实现高效承载。主星连接界面设计为对接环,推进舱一侧设计为对接框,对接接口为1194A标准接口,发射段通过包带实现连接,在轨包带解锁,实现了两舱分离。模态和静力仿真分析以及静力和振动试验验证了设计的合理性和可靠性。In response to the special requirements of the APSTAR-6E satellite structure with large load-bearing capacity,compact layout space,and detachable main satellite and propulsion module in orbit,this paper presents a new type of plate and frame combined satellite main structure based on a box plate structure with a frame system as the main load-bearing component.The plate frame hybrid structure not only provides an open,efficient,and convenient layout and installation space,but also solves satellite load-bearing problem.A new propulsion module structure has been designed with an internal storage tank and two external fuel tanks.The three storage tanks(one oxygen tank and two fuel tanks)are arranged in parallel to carry the load,which can reduce the center of mass of the satellite and achieve efficient carrying.The main satellite connection interface is designed as a docking ring,and the propulsion module side is designed as a docking frame.The docking interface uses 1194A standard interface.The launch segment is connected through a belt.When the belt unlocks in orbit,the two modules can successfully separate.Through modal and static simulation analysis,as well as static testing,the design rationality and reliability have verified.
