摘要
本文对空间构架式雷达罩进行了网格划分，运用薄膜理论加边界效应的连续化拟壳分析方法，分析了国内研制的直径２０ｍ、３／４截球型地面雷达罩在自重、雪载、风载作用时的壳体内力，并将壳体内力转化成杆件内力，进行了强度校核，为有限元数值解法提供了一个很好的参考依据．
In this paper, the space frame radar shade is grid-divided by using membrane theorm. The continuing quasi-shell analysis of edge effect is used to analyse the home- made 20 - meter- diameter, 3/4 spherical segment ground radar shade's shell inner force subjected to dead weight snow load and wind road. The shell inner force is trans ferred to member inner force and the strength is checked, which provides good references for finite elemetnt numerical method.
