简述了研究雷达天线风荷载和变形特性所用的测试仪器、测试方法及数据处理。给出了抛物面及圆锥形两种雷达天线的主要研究结果 ,结果表明对于所研究的构形圆锥天线的阻力和方位力矩系数分别为圆抛物面天线的 1.34倍和 4 .0倍 ,而最大弹性变形量却仅为圆抛物面天线的 75 % ,文中对上述两种雷达天线全然不同的风荷载及变形特性作了初步分析
The testing instruments, testing methods and data processing for studying wind load and deformation characteristics of radar antenna are briefly described. The main results of parabolic and conical radar antenna are given. The results show that the drag and azimuth moment coefficients of the conic antenna are 1.34 times and 4.0 times that of the circular parabolic antenna, respectively. The maximum elastic deformation But the volume is only 75% of the circular parabolic antenna. In this paper, we first make a preliminary analysis of the totally different wind loads and deformation characteristics of the two radar antennas
