Research on Alignment Correction Method Based on the Track Panel Characteristics of Medium and Low Speed Maglev
Research purposes:The medium and low speed maglev is generally designed as a dual line,the line type consisting of curves,transition curves,and straight lines.The special track panel characteristic of medium and low speed maglev requires high accuracy in line type,and its track geometry directly affects the safety and stability of maglev trains.To meet the static smoothness requirements for track panel installation,the track panel has been processed and matched with the line data before laying,and corresponds one by one.When the construction error of the offline project leads to the mismatch between the line type and the design,the same correction method as the wheel rail railway cannot be used.It is necessary to study a correction method suitable for medium and low speed maglev to calibrate the line type.Research conclusions:(1)To meet the static smoothness requirements of track panel installation and solve the problem of mismatch between the line type and the design caused by construction errors in offline project,this paper investigates a line alignment correction method suitable for medium and low speed maglev,which is different from the wheel rail railway line alignment correction method.The main steps are:pre-laying of track panels → fitting of line types→rearrangement of track panels→analysis of line type matching→laying of track panels.(2)Through practical case analysis,under the condition of controllable construction accuracy,this correction method can solve the problem of track laying caused by construction deviation in offline projects,avoiding situations where abandoned projects may occur due to the re-construction of offline foundations and the re-production of track panels.(3)The research conclusion can provide reference for the alignment correction of medium and low speed maglev.
