| 摘要: |
| 轨道几何状态是影响低速磁浮列车运行安全性和舒适性的重要指标，因此，必须定期测量轨道几何参数，并根据测量结果结果开展轨道维护，使轨道状态保持良好。利用FMS01完成了唐山1.5km低速磁浮轨道线路几何参数测量，结果表明，以用水准仪的精密测量高低结果为参考，FMS01的高低测量最大误差不超过±0.7mm；以多次测量的平均值为参考，各参数测量的最大误差不超过±0.2mm。 |

| Abstract: |
| The quality of F track has a critical influence on the safety and comfort of low speed maglev transportation. Therefore, track geometry must be measured termly. And Appropriate maintenance of F track will be carried out according as the measurement results to keep track all right. In order to maintain maglev guideway efficiently, FMS01 is a F track geometry measurement system made by National Univ. of Defense Technology and the first one in China, and it can be operated to measure track geometry fast and accurately, including vertical deviation, lateral deviation, track gauge and level difference when maglev train travel at 20-100km/h. Vertical and lateral deviation can be measured based on inertial principle. The measurements of the 1.5km long line in Tangshan was carried out using FMS01.The experimental results show that maximum error of vertical deviation is less than ±0.7 mm in reference to fine measurement using level gauge and maximum error of track geometries is less than ±0.2 mm in reference to the average of measurements using FMS01. |
