磁悬浮轨道几何参数测量方法研究
|
摘要
针对国内磁悬浮轨道几何参数测量技术发展滞后、第一代磁悬浮轨检设备量值溯源困难等问题,该文建立一套直接影响磁悬浮列车运行稳定和安全的几何参数评价体系,提出基于激光跟踪仪的磁悬浮轨道几何参数静态标定方法和磁悬浮轨检设备的比对办法。在唐山国家中低速磁浮交通试验基地的现场测量和比对实验表明,激光跟踪仪现场测量的扩展不确定度为0.50 mm,基于激光跟踪仪的现场实验比对可以有效地揭示磁悬浮轨检设备的系统误差,为新出现的磁悬浮轨检设备进行整体量值溯源提供新的思路。
Aiming at the problems that the domestic measurement technology for the geometric parameters of the maglev railway lags behind and there is no effective method of quantity traceability for the maglev railway inspection equipments, the paper systematically analyzed the main geometric parameters affecting the operation of maglev train and organized them into a set of evaluation system, then, presented a way of static calibration for the geometric parameters of maglev railway and a method of comparison experiment for the maglev railway inspection equipments based on the laser tracker. The situ measurement implemented in the Tangshan Low/medium-speed Maglev Experimental Line shows that the expanded uncertainty of the laser tracker in the field is 0.50 mm. The comparison based on the laser tracker effectively reveals the systematic deviation of the maglev railway inspection equipments and provides a whole new way of thinking for integrated quantity traceability of the emerging maglev railway inspection equipments.
