大型相控阵雷达天线骨架外场架设

Erection of Antenna Skeleton Outer Field of Large Phased Array Radar

对固定式大型相控阵雷达天线骨架发展趋势及结构形态进行了概述,大型相控阵雷达天线骨架由混凝土结构、钢混结构逐渐向钢结构方向发展,钢结构骨架具有造型多样、组装便利、施工周期短、施工过程绿色环保等突出特点,详细分析了钢结构骨架外场架设影响要素及架设流程,并针对某大型相控阵雷达钢结构天线骨架外型尺寸大、重量重、架设工作幅度大、精度要求高等特点,从吊装单元划分、吊点选择、吊绳布置、全过程仿真分析与核算、精度调整方法、架设工序及人员分配等维度进行了阐述,在保证钢骨架精度指标和外场架设安全性的同时,实现了全组装钢结构的快速架设。

The development trend and structure of stationary large phased-array radar antenna skeletons are outlined.The framework of large phased array radar antenna is gradually developing from concrete structure and steel structure towards the steel structure.The steel structure skeleton has many features,such as diverse modeling,convenient assembly,short construction period,and green environmental protection in construction engineering.The influencing factors and erection process of steel frame skeletons are analyzed in detail.A large phased array radar antenna skeleton of steel structure has large dimensions and weight.With the characteristics of heavy weight,large erection work,and high precision requirements,the latitudes of hoisting unit division,suspension point selection,suspension rope layout,whole process simulation analysis and accounting,precision adjustment method,erection process and personnel distribution are elaborated.Skeleton accuracy index and safety of field erection are guaranteed during the rapid erection of fully assembled steel structures.
