Abstract空间碎片对航天器安全造成很大威胁,为了分析宇宙环境中空间碎片对充气天线物理性能的影响,采用LS-DYNA软件定量给出空间碎片对充气天线外形的影响,进而分析了天线形面变形对电性能的降低和破坏,结果显示受较大尺寸空间碎片冲击时,充气天线会被穿透,必须补充一定的气体才能保持充气天线的形状和压力。
Other AbstractIn order to evaluate the influence of the debris on the inflatable antenna,the LS-DYNA program was used to perform the analysis.We first simulate the gas in the reflector using solid elements,consider-ing the coupling of membrane and gas.The result showed that the impact of debris can lead to gas leakage,the detail critical velocity with time was also analyzed.Finally we calculated the mass of gas needed to make up when adopting the continually making up scheme or inconsecutively one,which supports important statistics for the application of inflatable antenna.
