摘　　要：根据可展天线工作原理,结合地面工作环境特征,创新设计了集天线防护罩和可展索网天线于一体的地面伞状可展天线,进行了型面精度分析、等效静风荷载与脉动风荷载结构响应分析.分析结果表明:在8级风时索网反射面型面精度误差小于1.0mm,可正常工作.对地面伞状可展天线深入研究和应用具有参考价值.According to the operation principle and the operation environment related to the ground,a ground umbrella-type deployable antenna（UDA）was invented with integral of antenna canopy and deployable mesh reflector.The mesh reflector shape accuracy analysis and structural response evaluations were carried out for the UDA structure applied to equivalent static wind and fluctuating wind,as well as specific pre-stress.Computational results indicated that the UDA could operate normally and the shape accuracy error is 1.0mm lower in the condition of force 8wind.The presented work is valuable for futher study and application of the ground UDA.
