The operation mode of high speed maglev trains and wheel rail trains is different, and the unique infrastructure characteristics, signal systems, and high speed mobile equipment of high speed maglev trains make their operating mechanism different from wheel rail systems. The existing train tracking interval calculation methods and station parameter designs based on wheel rail relationships cannot be directly referenced and applied. Therefore, it is necessary to study the tracking interval calculation methods and station parameter designs for 600 km/h high speed maglev trains. On the premise of clarifying the tracking interval calculation method for high speed maglev trains, simulation calculations were carried out based on high speed maglev stations to study the influence of parameters such as arrival speed, acceleration and deceleration performance, turnout selection, and throat length of high speed maglev trains on the tracking interval of trains. The results indicate that for every 50 km/h increase in train arrival speed, the arrival tracking interval increases by approximately 27 s. For every 200 m increase in the throat length, t3 in the arrival tracking interval increases by approximately 7.3 s. When a turnout with a lateral speed of 98 km/h is used, for every 200 m increase in the throat length, t2 in the departure tracking interval increases by about 7.2 s. When a turnout with a lateral speed of 196 km/h is used, for every 200 m increase in the throat length, t2 in the departure tracking interval increases by about 5.6 s.
① 列车进站前运行速度与高速磁浮列车到达追踪间隔时间关系。高速磁浮列车到达追踪间隔时间与区间运行速度正相关,主要影响减速运行时段t2,区间运行速度每增加50 km/h,占用时间约增加27 s。高速磁浮列车到达追踪间隔时间与列车进站前运行速度变化关系如表3所示。
② 道岔侧向限速、咽喉区长度与高速磁浮列车到达追踪间隔时间关系。对于侧向限速98 km/h的咽喉区,咽喉区长度大于531 m时,列车运行状态为匀速—减速至咽喉区—以咽喉区限速匀速运行—减速至停靠站台,咽喉区长度对高速磁浮列车到达追踪间隔时间有影响。道岔侧向限速、咽喉区长度对高速磁浮列车到达追踪间隔时间的影响如表4所示。
