自串联发射卫星平台结构分系统设计与验证

Design and verification of structure subsystem of self-series satellite platform for one-rocket launch

与传统的一箭双星发射模式相比,卫星自串联发射具有更高的载荷比。文章面向支撑自串联一箭双星发射的全电推平台结构分系统研制,分析自串联发射卫星结构分系统的设计要求和特点,并提出适应自串联发射卫星平台的力学试验验证策略,实现了低成本、高效率的金字塔式验证。结果表明,支持自串联双星发射的结构平台成功通过力学环境试验考核,相关设计及试验方法可为同类航天器结构研制提供参考借鉴。

Compared with the traditional two satellites with one rocket launch mode,the self-series satellite launch allows a higher payload ratio.This paper reviews the development of the structure subsystem of the allelectric propulsion satellite platform which supports the self-series satellite launch.The design requirements and the characteristics of the structure subsystem of the self-series satellite platform are discussed,and a mechanical test validation strategy for the satellite platform is proposed for the pyramid validation with low cost and high efficiency.The structural platform supporting the self-series satellite launch has passed the mechanical environment tests successfully.The design and test method can help the development of similar spacecraft structure subsystems.
