摘要
文中针对某高精度相控阵雷达天线座采用的锥面滚轮结构,研究了滚轮和轨道对应的空间关系,总结出了计算公式,并在此基础上确定了天线座方位承载滚轮及轨道设计方案。在安装调整过程中,根据激光跟踪仪极坐标原理进行了点位坐标测量,用靶镜直接测量平面来确定滚轮内平面的法线方向、靶镜配合工装测滚轮锥面来确定圆心的方法确定了滚轮的轴线和位置,有效指导了滚轮的安装调整,满足了其向心度和位置度设计要求。
According to the cone wheel structure of a high-precision phased array radar antenna pedestal system,the spatial relationships between the wheel and track are studied,the computation formulas are concluded and the design scheme for wheel and track is confirmed on this basis. During the installation and adjustment of the wheel on track,the point position coordinate measurement is carried out according to the polar coordinate principle of the laser tracker. The plane is measured directly by the spherically mounted retroreflectors(SMR) to find the normal line direction of the wheel inner plane and the wheel cone plane is measured by SMR together with the fixture to find the center of the circle. The axis and position of the wheel are thus obtained with this method. The result shows that the method can direct the installation and adjustment effectively and meet the centrality and position design requirements of the wheel.
