某大型天线骨架的安装

Assembly of a Large Antenna Framework

大型天线骨架作为某远程测量雷达的天线载体,具有面积大、精度高、安装复杂的特点。文中针对某天线骨架的结构特点和精度要求,分析了天线骨架的装配难点及影响安装精度的因素。通过优化装配流程、合理安排天线骨架的安装顺序、采用预装后再正式装配的方法,最终实现了天线骨架的安装精度,可为该类型天线骨架的安装提供参考。

As the antenna carrier of some long-range instrumentation radar, the large antenna framework is characterized by large area, high accuracy and extreme difficulty to assembly. In this paper, according to the characteristics and accuracy requirement of the antenna framework, assembly difficulties and factors affecting assembly accuracy are analyzed. By optimizing the assembly process, a new assembly method is proposed. The reasonable assembly sequence is adopted, in which the antenna framework is pre-assembled before formal assembly. As a result, the final assembly accuracy of the antenna framework is ensured. This method can be applied to the assembly of this kind of antenna framework.
