The presence of wrinkles in the membrane is the main factor to induce the reflector surface inaccuracy of the space inflatable
antenna. Based on the commercial finite element package ABAQUS, a numerical procedure for membrane wrinkle analysis was set
up and used to analyze a space inflatable antenna which was under inner pressure to evaluate its wrinkle characteristics.
First, the inner pressure effect on the reflector’s wrinkle pattern was studied thoroughly. As inner pressure increases, both
the number and the amplitude of the wrinkles decrease, but the total deformation of the whole reflector surface increases
much. Second, the influence of the interactions between antenna’s parts was investigated comprehensively. Any kind of unwanted
interaction deteriorates reflector’s wrinkle characteristics. The works are valuable to the development and research of the
space inflatable antenna. 相似文献
