摘要:
中低速磁浮线路轨道因考虑热胀冷缩等因素，轨道由定长的轨排通过轨排接头进行过渡连接，在线路中会形成诸多轨缝。首先分析了轨缝对于悬浮传感器检测性能的影响，并分析了中低速磁浮轨道的F轨在温升作用下的热变形，基于车辆悬浮稳定性要求提出了车辆对轨缝设计的相关要求，并对国内某磁浮试验线上的轨缝值进行统计与评估，提出了相应的改善方案。
Abstracts:
Due to the consideration of thermal expansion and cold contraction of medium and low speed maglev track, the track is transiently connected by fixed length rails through rail joint, in which process many rail gaps are formed. The influence of track gap on the detection performance of suspension sensor and the thermal deformation of F-rail of medium and low speed maglev track under the effect of temperature rise are analyzed. In line with vehicle suspension stability specification, relevant requirements from vehicle towards track gap design are put forward. Statistics and evaluation on the track gap value of certain domestic maglev test line is carried out, and corresponding improvement plans are proposed.
