摘要
简要介绍了大型航天器装配检测对航天器研制的意义,如舱段结构尺寸精度测量、设备安装位姿测量、机构位姿动态监测、结构变形监测等。分析了美国NASA、欧洲ESA以及中国等世界主要宇航机构大型航天器装配检测技术现状,列出了当前常用的装配检测方法和技术指标,剖析了测量原理。结合未来大型航天器尺寸越来越大、精度要求越来越高、任务越来越复杂等特点和装配检测需求,讨论了未来大型航天器装配检测技术的发展趋势,重点分析了多系统集成测量技术的发展、定制化的测量传感器研制以及自动化测量设备开发等发展趋势。
The significance of metrology during aligning and building large scale spacecraft is briefly introduced, it includes dimensional accuracy inspection, posture inspection, moment monitoring and deformation monitoring, and so on.Metrology tools, techniques and applications in some top aerospace corporation, such as NASA, ESA, CAST, are listed and specifications and theories are analyzed. With the increasing of spacecraft volume and assembly precision, some new metrologies are being studied and some new type of metrology system are being developed. Multi-system fusion metrology, new survey sensors and some type automated measurement equipments are focused.
