一种大型天线阵面自动调姿设备的设计及测量

为了让大尺寸相控阵雷达天线阵面在装配过程中可以实时变换姿态，以达到高效装配的目的，文中设计了一种自动调姿设备，在天线阵面的长度方向与其两端进行连接，通过自动调姿设备旋转轴的转动实现天线阵面的姿态变换。为了满足调姿设备两端旋转轴线的高精度同轴度要求，建立测量基准，采用柔性三坐标仪器标校测量基准与旋转轴线的位置关系，采用激光跟踪仪测量基准的方法，高效指导了自动调姿设备的安装调整，有效保证了两端旋转轴线同轴度的高精度要求。

Design and Measurement of Automatic State Transformation Equipment for Large-scale Antenna Array

In order to change the state of large-scale antenna array of phased array radar in real time in assembly process, the automatic state transformation equipment is designed to improve assembly efficiency greatly. The equipment is connected with antenna array in length direction and the change of antenna array state is realized by the rotation of the equipment. To meet the requirement of high-precision concentricity of rotation axis at both ends of the equipment, the methods are proposed that the measurement benchmark is established, the positional relation of the measurement benchmark and the rotation axis of the equipment is corrected through the flexible coordinate measuring instrument and the benchmark is measured and adjusted through laser tracker. The methods are used to guide the installation and adjustment of the equipment efficiently and ensure the high precision requirement of the concentricity of the rotation axis at both ends of the equipment effectively.
