Description

Technical Field

[0001] This invention relates to the field of engineering technology for modeling and simulation of conventional high-speed maglev, and in particular to a finite element modeling method and system for conventional high-speed maglev considering the horizontal and vertical curves of the track. Background Technology

[0002] With the advancement of technology and the rapid development of the transportation industry, high-speed maglev technology has gradually transitioned from theory to practice. The basic electrical principle of maglev trains is a linear motor, which consists of a long stator coil on the ground and a moving coil on the vehicle. The long stator coil on the ground needs to provide a levitation and guiding magnetic field to complete the electromagnetic levitation and power drive of the train.

[0003] In the process of transitioning from theory to engineering, it is necessary to conduct simulation analysis of linear motors under actual engineering conditions. In particular, it is necessary to analyze the electromagnetic characteristics, dynamic characteristics, and possible operating conditions of linear motors under various actual engineering conditions, so as to provide guidance and basis for the engineering scheme of conventional high-speed maglev.

[0004] For high-speed maglev systems, the levitation and guidance of the entire vehicle body rely entirely on electromagnetic force, requiring high stability of the magnetic field. However, during the engineering process, there are many non-ideal conditions, and different environmental conditions and special circumstances need to be considered. At the same time, different construction conditions will be faced during the construction and laying process. It is necessary to identify the key engineering constraints affecting conventional high-speed maglev. Furthermore, the engineered high-speed maglev line cannot be directly and ideally a straight line. It is necessary to build a reasonable and effective finite element simulation model to systematically analyze the electromagnetic and dynamic characteristics of the high-speed maglev system under different horizontal and vertical curve conditions.

[0005] In the engineering implementation of conventional high-speed maglev long stators, different horizontal and vertical curve conditions of different lines are unavoidable. The different line conditions will inevitably affect the electromagnetic performance of the conventional high-speed maglev linear motor.

[0047] The present invention provides a finite element modeling method for conventional high-speed maglev trains that considers the horizontal and vertical curves of the track, further comprising the following steps:

[0049] According to the present invention, a finite element modeling method for a normal-conducting high-speed maglev train considering the horizontal and vertical curves of the line is provided, wherein an excitation current is applied to the mover of the sample normal-conducting high-speed maglev train, a cable current is applied to the stator of the sample normal-conducting high-speed maglev train, and the actual feedback value of the sample normal-conducting high-speed maglev train is obtained.

[0050] The feedback values ​​of the finite element model are compared with the actual feedback values. If the difference between the two is less than a preset error threshold, the finite element model is determined to meet the requirements.

[0051] According to the present invention, a finite element modeling method for conventional high-speed maglev trains considering the horizontal and vertical curves of the track is provided, wherein obtaining the design dimensions of the conventional high-speed maglev train to be modeled and establishing a model of the conventional high-speed maglev linear motor includes:

[0052] Obtain the basic line contour of the mover core to form the electromagnetic dimension contour;

[0053] And based on the basic line outline, draw the groove structure according to the design parameters;

[0054] Draw the moving rotor excitation coil and apply the excitation current;

[0055] A finite element simulation model of the mover is established based on the actual linear array mover unit of the maglev vehicle.

[0056] According to the present invention, a finite element modeling method for conventional high-speed maglev trains considering the horizontal and vertical curves of the track is provided, wherein obtaining the design dimensions of the long stator of the conventional high-speed maglev train and establishing a unit model of the linear motor of the conventional high-speed maglev train includes:

[0057] Obtain the basic line contour of the long stator core to form the electromagnetic dimension contour;

[0058] And based on the basic line outline, draw the groove structure according to the design parameters;

[0059] Draw a long stator cable and apply current;

[0060] Based on the actual linear array long stator unit of the maglev vehicle, a finite element simulation model of the long stator is established.

[0061] In one specific embodiment, the present invention provides a finite element modeling method for normal-conducting high-speed maglev trains that considers the horizontal and vertical curves of the track, comprising:

[0062] Based on the cross-sectional dimensions of the conventional maglev linear motor and the lengths of the stator and mover along the direction of travel (each car has a mover with 14 poles on one side and is covered by a long stator that can generate a magnetic field of 20 poles), a finite element simulation model of the conventional maglev linear motor under ideal conditions is drawn.

[0063] Taking the mover unit as an example, first, the basic lines of the mover core are drawn to form the outline of each part. Then, the production region is created, and all slot areas in the drawing are linearly arrayed and mirrored. Boolean operations are then used to subtract the corresponding slot areas from the total core area, forming the mover core. The mover excitation coil is generated by creating a new sketch, using the "Project Outline to Sketch" function to constrain its position, and then performing operations such as region generation, mirroring, and linear arraying.

[0064] The long stator unit is modeled using a similar method. First, basic lines are drawn, then each region is generated and Boolean operations are performed. The position of the stator coil is constrained by the entity reference conversion function to generate the model of the long stator unit.

[0065] Based on the aforementioned number of stators and movers, a simulation model of the ideal normal-conducting magnetic levitation linear motor can be obtained by performing linear array operations on the stator and mover respectively.

[0066] In the engineering implementation of long stators for conventional high-speed maglev trains, different horizontal and vertical curves on the track are unavoidable, and these variations will inevitably affect the electromagnetic performance of the linear motor. To analyze this impact, a finite element modeling method for the electromagnetic performance of the linear motor of a conventional high-speed maglev train that considers the horizontal and vertical curves of the track is introduced. This method selects elements that are prone to error or deflection, and after completing the above steps, further parametric analysis of the error or deflection can be performed.

[0067] This invention introduces a finite element modeling method for conventional high-speed maglev trains that considers beam joint errors. Taking the vertical curve of a planned conventional high-speed maglev line as an example, the stator and mover are tilted at a certain angle along the horizontal axis. Selecting the long stator component, the Region Move function is used, specifying the movement mode as Rotate, and the rotation center as the lower left corner of the mover core. The rotation axis is perpendicular to the paper, and the corresponding slope angle is given according to the vertical curve gradient. This completes the finite element modeling of the conventional high-speed maglev linear motor considering the vertical curve of the line. Taking the curve of a planned conventional high-speed maglev line as an example, the stator and mover are rotated at certain left and right intervals along the planar axis. Selecting the long stator component, the Region Move function is used, specifying the movement mode as Rotate, and the rotation center as the lower left corner of the mover core. The rotation axis is parallel to the paper, and the corresponding interval is given according to the horizontal curve radius. This completes the finite element modeling of the conventional high-speed maglev linear motor considering the horizontal curve of the line.

[0068] On the other hand, such as Figure 2 As shown, the present invention also provides a finite element modeling system for normal-conducting high-speed maglev considering the horizontal and vertical curves of the line.

[0069] The curve processing module is used to extract the planar curve and longitudinal curve of the normal-conducting high-speed maglev train to be modeled, and generate the spatial center curve of the current line.

[0070] The mover modeling module is used to obtain the design dimensions of the normal-conducting high-speed magnetic float to be modeled and to establish the mover model of the normal-conducting high-speed magnetic float linear motor.

[0071] The stator modeling module is used to obtain the design dimensions of the long stator of the normal-conducting high-speed maglev, and to establish the stator unit model of the normal-conducting high-speed maglev linear motor. The long stator of the normal-conducting high-speed maglev is divided into multiple stator units. According to the spatial center curve of the curve processing module, the horizontal rotation angle and longitudinal rotation angle of each stator unit along the direction of travel are set in sequence to establish the models of multiple stator units and the overall stator model.

[0072] The model matching module is used to match the overall stator model with the model of the normal-conducting high-speed maglev linear motor corresponding to the mover, so as to obtain the finite element model of the current normal-conducting high-speed maglev.
