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。
In order to analyze the impact of space debris on the physical performance of the airborne antenna in the space environment, the space debris impact on the spacecraft antenna shape is quantitatively analyzed by using LS-DYNA software. Then the deformation of the antenna surface is analyzed Decreasing and destroying the electrical performance has shown that the inflatable antenna will be pierced by the impact of larger size space debris and must be supplemented with a certain amount of gas to maintain the shape and pressure of the inflatable antenna.
