集主承力结构与大容量储箱支架于一体的卫星主承力筒结构研究

针对现代卫星结构的大型化、燃料储箱的大型化,提出了一种集主承力结构与大容量储箱支架一体化的卫星主承力筒结构形式,旨在降低卫星质心、提高基频;在满足储箱容积的前提下,又能满足主结构有效载荷往运载的力的传递作用.有限元数值计算表明,该结构形式能够满足卫星相关结构性能的要求,可以作为今后卫星结构设计的参考构型.

The Research on Main Satellite Bobbin Cylinder Incorporated With Main Heary Structure and Bracket of Large-Volume Tank

With the background of the large-scale of modern satellite structure and propellant tank, a format of main satellite bobbin cylinder incorporated with main heary structure and bracket of large-volume tank, are proposed aiming at lowering the centroid and increase the fundamental frequency. The new structure type can meet the requirements of both the design of tank volume and the mechanical transferring efficiency from payload of main structure to carry. The numerical computation of finite element method indicates that the proposed structure format can meet the requirement of relevant structure performances and can server as the referential configuration of satellite structural design in the future. The main bobbin structure is weaved by high modulus carbon fiber, the cylinder of which is embedded a carbon fiber board inside. The designability and spreading weavablility should be made full use of to produce it according to the need.
