【摘要】 空间充气展开天线是一种薄壁结构,其力学特性与传统结构天线有显著不同。本文考虑天线支撑结构的薄壁结构特点,建立了支撑结构的有限元模型。采用ANSYS 分析了不同荷载条件下充气天线支撑结构的应力分布,并考虑了充气压力对支撑结构力学特性的影响,分析结果表明,充气压力对支撑结构力学特性有很大影响。更多还原

【Abstract】 Space inflatable antenna is a kind of membrane structure,which has different mechanicalperformance from traditional antenna.In this paper,a finite element model of support structure is set upconsidering the membrane characteristic of support structure of space inflatable antenna.ANSYS is used toanalyze the stress distribution of support structure under different load conditions.The influence of inflationpressure on the mechanical performance of support structure is investigated.The results show that the inflationpressure has a great influence on the mechanics performance of the support structure.更多还原
