大型SAR载荷外挂的卫星主承力结构设计
Main Bearing Structure Design of Satellite with External Large SAR Payload
摘要
Abstract
To the difficulties of satellite structure with external large SAR payload,indirect pay-load path and concentrated complicated force in mounting interface,a main bearing structure with combination of panel-cylinder and internal reinforcing was proposed.Based on panel-cylinder structure platform,the structure of GF-3 satellite domestic first external large SAR satellite in China was improved to meet the requirement by laying six run-through beams and rational panel layout.The beams are placed in pressing mounting points of SAR payload.The difficulties owing to indirect mounting of SAR payload were solved,including the low lognitudinal frequency,con-centrated stress of mounting points and so on.关键词
