Curve Fitting Techniques in Guideway Design of High-Speed Maglev TR System

This paper gives a detailed description of the guideway structure of high-speed maglev TR system and the precision requirements of three function planes. Short lines and curves are used to fit stator plane, guidance rail plane and sliding rail plane in the curve section of maglev track. Furthermore, the curve fitting method in detail and the analysis process on data are presented and the reasonable span of vertical radius as well as the reasonable span, the allowable span and dominant radius span are obtained using the modules of different lengths, the stators of different layout modes and the guidance rail planes of different radius values. This paper also compares the above results with the lower limit value of horizontal and vertical radius calculated from the theory of vehicle movement dynamics.
