Abstract
Description
Technical Field
[0001] This invention relates to the technical field of high-speed maglev railway construction, and in particular to a high-speed maglev track positioning design method. Background Technology
[0002] High-speed maglev lines are designed for speeds exceeding 400 km / h and employ long stator drive technology. Functional components are connected to the track beams via bolts, providing load-bearing and guiding functions. The stator, installed inside the functional components, provides levitation and driving functions. High-speed maglev lines are constructed by orderly splicing track beams of a certain length, functional components, and the stator according to theoretical spatial curves, resulting in high smoothness. To improve the smoothness of high-speed maglev lines, compared to traditional railways, two relatively special transition curves—a sine wave and a single-wave sine wave—are used. These transition curves, compared to traditional cubic parabolic transition curves, ensure continuous function values at different line transition points. However, the function expression is extremely complex, belonging to multi-layered composite functions requiring integration. High-precision positioning of track components (functional components and the stator) is challenging, and construction is difficult. Furthermore, if the track beams, functional components, and stator are simply spliced end-to-end, it will cause a significant deviation between the track components (functional components and stator) and the ideal spatial curve of the maglev line, failing to meet the high smoothness design requirements of high-speed maglev lines. To reduce the form and position deviations caused by the track beams and track components fitting the line with a straight line and to improve the line fitting effect, the track beams, functional components, and stator are arranged according to the "half-sagittal height" principle. When arranging the track components, the impact of factors such as temperature changes and magnetic field distribution on track engineering and vehicle operating performance must also be considered. It is evident that the design of a high-speed maglev system is a complex engineering project.
[0003] However, the design of track components for high-speed maglev railway construction in China lacks precise positioning coordinate information, which is detrimental to the precision control of the installation and construction of high-speed maglev functional components and stators. Summary of the Invention
[0004] The purpose of this invention is to solve the problem of the lack of precise positioning coordinate information in the design of track components for the construction of high-speed maglev railways in the existing technology, and to provide a high-speed maglev track positioning design method.
[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:
[0006] A high-speed maglev track positioning design method includes the following steps:
[0007] High-speed maglev lines are classified according to their alignment. Each line segment is a single line type, and a local coordinate system is created at the starting point of each line segment.
[0008] Get the Linear equations of line segments ,in , obtain the Local coordinate system of line segment unit The coordinate axes relative to the global coordinate system Angles between corresponding coordinate axes , and ,according to , , and Obtain the overall spatial curve equations of high-speed maglev lines ;
[0009] According to the Positioning points of track components on section line unit To the corresponding local coordinate system origin Mileage along the direction of the high-speed maglev line , obtain the Positioning points of track components in a section of track Position coordinates in the corresponding local coordinate system ,in ,according to and the Positioning points of track components in a section of track To the origin of the global coordinate system Mileage ,Will Convert to position coordinates in the global coordinate system ,in It is a point Around the local coordinate system Angle of axis It is a point Around the local coordinate system Angle of axis It is a point Around the local coordinate system Angle of axis It is a point Around the global coordinate system Angle of axis It is a point Around the global coordinate system Angle of axis It is a point Around the global coordinate system Angle of the axis;
[0010] The track components of each line unit are arranged according to the position coordinates of their corresponding positioning points in the global coordinate system to complete the positioning design of the high-speed maglev track.
[0011] High-speed maglev lines include simple alignments such as straight lines, spiral transition curves, vertical curves, single-wave sinusoidal transition curves, or planar circular curves. A single alignment type refers to one of these types. When the alignment equation of a certain line segment is obtained, the starting and ending coordinates of that segment in the corresponding local coordinate system can also be obtained. According to the... Determination of key parameters such as alignment type, gradient, and length of a section of track. Find the solution. Afterwards, Sequential translation and rotation are used to obtain the local coordinate system and line type equations of other segments. The segmented linear equations form the overall spatial curve equation system of the high-speed maglev line. In obtaining the first Positioning points of track components in a section of track At that time, the first A track segment unit may contain at least one track component, but each track component requires corresponding positioning points. Positioning points of track components in a section of track To the origin of the global coordinate system Mileage That is, along the origin of the high-speed maglev line. To the location point The distance traveled. The positioning point. Coordinates in the local coordinate system Convert to coordinates in the global coordinate system through translation and rotation. At that time, based on the positioning point To the origin of the global coordinate system Mileage Determine the location point Need to be brought in Which segment, and thus perform coordinate transformation.

[0015] As a preferred embodiment of the present invention, after arranging the track components of each line unit according to the position coordinates of the corresponding positioning points in the global coordinate system, the beam gaps of the track beam, the spacing between two adjacent functional components, and the spacing between two adjacent stators are checked to see if they meet the standard requirements. If they meet the standard requirements, the positioning design of the high-speed maglev track is completed; if they do not meet the standard requirements, the arrangement scheme of the track components is changed until the standard requirements are met.
[0016] Non-compliance with standard requirements includes: contact between the inner stators of the high-speed maglev track; beam gaps in the track beams smaller than specified; and spacing between adjacent functional components smaller than required. This is because the track component layout was determined based on positioning points, without considering the actual lengths of the stators, track beam functional components, and track beams; therefore, verification is necessary. When changing the track component layout, first modify the layout of the track components that do not meet the standard requirements. If other track components require adaptive modifications, those modifications should also be made accordingly.
