Embodiment 1

[0057] Embodiment 1: with reference to attached Figure 1-12 . The invention relates to a switch control sequence of a high-speed maglev switch, in particular to a switch control sequence of a high-speed maglev switch. The method of the invention is composed of one or more combinations of determining key trolley layout positions, determining key elements of switch sequence, proposing a control method for switch sequence, and determining switch sequence through comparative calculation and optimization.

[0058] (1) Layout position of key trolleys

[0059] Such as figure 2 As shown in Fig. 1, according to the line shape requirements of the turnout "straight line - transitional curve - circular curve - transitional curve - straight line", the plane combination composed of five piecewise functions is used to fit the bending curve of the turnout steel beam. Through the analysis of material mechanics, the shear force on the cross section of the turnout beam between points 2#~6# ...

Abstract

The invention relates to a high-speed maglev turnout switch control time sequence which can solve the problems that in a method for determining a switch time sequence through a field test, the field time sequence debugging workload is large, part of structures of turnouts are prone to being damaged in the debugging process, and the proper switch time sequence of the turnouts cannot be determined within a short time. Various switch working conditions of the turnout are calculated, analyzed and optimized through a finite element method, the method has the advantages of being high in design efficiency, high in flexibility, accurate in result and the like, the service life of a turnout structure is prolonged, the power of a driving motor is reduced, and the situation that a turnout stepped pinis large in stress is improved; and the defects of quality risk and low reliability determined by a high-speed maglev turnout switch time sequence field test are effectively overcome.

Description

technical field [0001] The invention relates to a high-speed maglev turnout capable of solving the problem that the on-site sequence debugging workload of the field test method for determining the switch sequence is large, the structure of the turnout is likely to be damaged during the debugging process, and the suitable switch sequence of the switch cannot be determined in a short time A switch control sequence belongs to the technical field of urban rail transit. Background technique [0002] (1) Zhu Zhiwei. Research on Drive Arrangement of High-Speed ​​Turnouts on High-Speed ​​Maglev Lines [J]. Urban Rail Transit Research, 2011(5):83. This document introduces the driving scheme of the world's first high-speed magnetic levitation line high-speed turnout driven by a pair of motors and driven by rack and pinion. Through geometric nonlinear analysis, the characteristics of high-speed turnout switching process under different driving layout schemes are compared, and the layou...
