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.
In view of the large size of the modern satellite structure and the large size of the fuel tank, a satellite main force tube structure integrating the main bearing structure and the large capacity tank bracket is proposed to reduce the satellite centroid and increase the fundamental frequency , Which can meet the transmission of the main structural payload to the carrying capacity under the premise of meeting the tank volume.The finite element numerical calculation shows that the structural form can meet the requirements of the satellite related structural performance and can be used as the future satellite structure design Reference configuration.
