英文摘要	In order to improve the concentration efficiency and eliminate the optical aberration, the umbrella-shaped keel structure has been introduced into the deployable concentrator. The concentration performance of deployable solar paraboloid concentrator with concentration power of which working in the space environment has been investigated with the software and . Under the influence of film tension and solar wind, the maximum stress of umbrella fabric is , is which is much smaller than the threshold intensity of and keel materials. The maximum deformation of umbrella fabric is , radius of the spot size is , the geometric concentration ratio could achieve , which only reduced than the standard parabolic concentrator. The results reveal that the influence of film tension and solar wind on the working shape of concentrator has been offset to a large extent by the introduction of umbrella-shaped keel structure, which would eliminate wrinkle and enhance the umbrella-shaped keel concentrator abilities of deployable and stability, as well as the selected umbrella-shaped keel structure and materials are appropriate.
