Edges interference errordetection and reflector gaps correction for large-scale compact range

  • 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.
