摘要

摘要: 为了避免由单块反射面边缘误差导致拼缝产生物理干涉并引起反射面受力变形，保证大型紧缩场最终的型面精度及电气性能，针对典型的紧缩场反射面形式，在评价单块反射面边缘轮廓度的基础上，建立统一的正交距离回归模型，用于计算单块反射面的标称尺寸、干涉误差以及边缘的修正量，并对整体拼缝干涉高风险区进行预估及修正.利用激光跟踪仪对某大型紧缩场单块反射面边缘进行了测量，应用上述方法分析并修正了干涉高风险区，保证该紧缩场的拼缝宽度满足（0.4±0.2）mm的设计指标.

Abstract: In order to avoid the physical interference and reflecting surface deformation caused by a single reflector edge error, and ensure the final surface accuracy and electrical performance of large-scale compact range, an unified orthogonal distance regression model taking account of the typical forms of compact range(CR) reflection surface was proposed based on the evaluation of single reflector panel edge profile tolerance. And this model was employed to calculate the panels' nominal size, interference error and edge correction.Meanwhile this model also could be used to predict and mend the overall gaps interference high risk area. The single reflector's edges of a large compact range were measured by a laser tracker. After analyzing and correcting the high interference risk areas through the above approach, the CR gaps satisfied the design index of (0.4±0.2) mm.
