Description

Technical Field

[0001] The present invention relates to the technical field of maglev technology, and more particularly, to a device and method for measuring the levitation force and guiding force of an electromagnet based on a track spectrum. Background Art

[0002] The content of this part only provides background information related to the present invention, which may not constitute prior art.

[0003] With the acceleration of the urbanization process and the development of regional economic integration, medium and low-capacity maglev transportation, as an efficient and environmentally friendly rail transit mode, has received extensive attention.

[0004] In medium and low-capacity maglev transportation, the levitation principle of medium and low-speed maglev vehicles is to generate levitation force through the interaction between on-vehicle electromagnets and the track, enabling the vehicle to levitate and run. At the same time, the component of the levitation force generated by the misalignment between the electromagnet and the track (i.e., the guiding force) is used to achieve vehicle guidance. However, during actual operation, the levitation force and guiding force are affected by various factors, such as vehicle speed, line conditions, and track irregularities. If the levitation force is less than the vehicle's gravity, it will cause the maglev vehicle to derail, that is, the suspension frame will fall onto the track and be towed by skids, which will seriously affect the service life and running comfort of vehicle components.

[0005] To ensure the safe operation of medium and low-speed maglev vehicles and achieve performance optimization, the research of levitation system technology and product design are crucial. During the research and product development of the levitation system, it is necessary to accurately measure the levitation force and guiding force of the electromagnet under different track conditions to determine whether the performance of the levitation controller and electromagnet products can meet the actual operation requirements of the vehicle.

[0006] In related technologies, known test devices have certain limitations when measuring levitation force and guiding force. For example, in the measuring devices disclosed in the patent documents with publication numbers "CN115014610B" and title "An Electromagnet Test Bench", "CN114966494B" and title "Multi-Maglev System Measuring Device Based on Magnetic-Thermal Multi-Field Coupling and Its Measuring Method", and "CN117724022A" and title "A Test Device and Method for Levitation Electromagnets of Maglev Trains", although the measurement of levitation force and guiding force can be achieved, during the test process, the electromagnet and the track always remain in an ideal parallel state. This design cannot adjust the position of the electromagnet and the track according to the complex relative position relationship between the electromagnet and the track in the track spectrum, so that the complex relative position relationship between the electromagnet and the track during actual operation cannot be more realistically simulated, and thus the levitation force and guiding force based on the track spectrum cannot be measured more accurately.

Detailed implementation manners

[0046] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the detailed implementation manners. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0047] Compared with the embodiments shown in the drawings, the feasible implementation solutions within the protection scope of the present invention may have fewer components, have other components not shown in the drawings, different components, components arranged differently or components connected differently, etc. In addition, two or more components in the drawings may be implemented in a single component, or a single component shown in the drawings may be implemented as multiple separate components.

[0048] An embodiment of the present invention discloses an electromagnet suspension force and guiding force measuring device based on a track spectrum, in the hope of being able to simulate the complex relative position relationship between the track and the electromagnet during the actual operation of the maglev vehicle based on the track spectrum, so as to provide the possibility for measuring more real and practical suspension force and guiding force.

[0049] Among them, the track spectrum described in the present invention refers to the statistical characteristic description of track irregularities, which reflects the random changes in the track geometry. Generally, the track spectrum file contains the irregularity information along the track forward direction, usually represented by a number of data points. These data points describe the geometric shape deviations of the track at different positions, including parameters such as elevation, alignment, level, gauge and twist. The track spectrum has important applications in engineering, especially in railway engineering and vehicle dynamics simulation. Through the track spectrum file, various relative position states between the track and the electromagnet can be intuitively obtained.

[0050] For the sake of simplicity of description, hereinafter, the electromagnet suspension force and guiding force measuring device based on the track spectrum disclosed in the embodiments of the present invention will be simply referred to as the "measuring device".

[0051] Figure 1 The structural schematic diagram of the exemplary measurement device disclosed in the embodiments of the present invention. In Figure 1 the illustrated embodiment, the measurement device may include a bench 10, a magnetic levitation assembly 20, a first fixing assembly 30, a second fixing assembly 40, a horizontal driving member 50, a plurality of vertical driving members 60, and a force detection assembly 70.

[0052] The bench 10 is mainly used to provide a carrier for the installation of components such as the first fixing assembly 30 and the plurality of vertical driving members 60, and is used to reliably support the entire measurement device on the ground for use.

[0053] Specifically, as Figure 2 shown, the bench 10 may include two symmetrically arranged frames 11. Each frame 11 may be a U-shaped structure with a smaller upper part and a larger lower part, and the positions of the two frames 11 close to their respective bottom ends may be connected by a first connecting frame 12. The first connecting frame 12 is mainly used to provide a carrier for the installation of the first fixing assembly 30. Exemplarily, a first mounting seat 13 suitable for installing the first fixing assembly 30 may be provided on the first connecting frame 12.

[0054] A horizontal steel plate anchor 14 may also be provided at the bottom of the frame 11. The steel plate anchor 14 is used to transfer the weight of the entire measurement device to the ground to support the entire measurement device on the ground for use

[0055] Continuing to refer to Figure 2 , the bench 10 may further include a second connecting frame 15. The second connecting frame 15 may be arranged above the first connecting frame 12, and both sides of the second connecting frame 15 are respectively connected to the two frames 11, especially the tops of the two frames 11. In this embodiment, the first connecting frame 12 and the second connecting frame 15 are parallel to each other.

[0056] Among them, the second connecting frame 15 is mainly used to provide a carrier for the installation of the plurality of vertical driving members 60. Exemplarily, second mounting seats 16 corresponding to the vertical driving members 60 one by one may be provided on the second connecting frame 15, and each second mounting seat 16 is used to install the corresponding vertical driving member 60.

[0057] Moreover, a strengthening beam 17 may be provided between the two frames 11 located between the first connecting frame 12 and the second connecting frame 15 to further improve the structural stability of the bench 10.

[0058] It is understandable that by adopting two frameworks 11 with a smaller upper part and a larger lower part, and cooperating with the first connecting frame 12, the second connecting frame 15 and the steel plate anchor 14, while providing a carrier for the installation of the first fixing component 30 and multiple vertical driving components 60, the stability of supporting the entire measuring device on the ground can be effectively improved. Among them, components such as the framework 11, the first connecting frame 12, and the second connecting frame 15 can be welded by thick-walled square steel pipes, and the whole has a certain strength to avoid adverse effects such as deformation and tremor during the suspension force and guiding force tests.

[0059] Of course, in other embodiments of the present invention, the bench 10 may also have other suitable structural forms.

[0060] The magnetic levitation component 20 is a part of the maglev vehicle that provides suspension force and guiding force for the car body of the maglev vehicle.

[0061] Specifically, as Figure 3 shown, the magnetic levitation component 20 may include a track 21 and an electromagnet 22 extending along the same axial direction. The track 21 described in the present invention is also the track 21 used in known maglev vehicles, such as F-track, U-track, etc.; the electromagnet 22 is also the electromagnet 22 used in known maglev vehicles. In a maglev vehicle, the track 21 and the electromagnet 22 are generally arranged opposite to each other and parallel to each other. When the electromagnet 22 is energized, through the cooperation of the electromagnet 22 and the track 21, a suspension force that enables the car body of the maglev vehicle to levitate and a guiding force for guiding the car body of the maglev vehicle can be generated. The measuring device disclosed in the present invention is used to measure the suspension force and guiding force between the electromagnet 22 and the track 21 when the electromagnet 22 is energized.

[0062] Referring to Figure 1 shown, the first fixing component 30 can be arranged on the bench 10, especially on the first mounting seat 13 on the first connecting frame 12. Among them, the first fixing component 30 is mainly used to provide a carrier for the installation of the first test piece, so that the first fixing component 30 can position the first test piece in a state parallel to the ground.

[0063] The second fixing component 40 is arranged opposite to the first fixing component 30 in the vertical direction. For example, the second fixing component 40 can be arranged above the first fixing component 30 and opposite to it. Among them, the second fixing component 40 is mainly used to provide a carrier for the installation of the horizontal driving component 50. For example, the horizontal driving component 50 can be installed at the bottom of the second fixing component 40.

[0064] The horizontal driving component 50 is suitable for installing the second test piece to position the second test piece at a position opposite to the first test piece. And the horizontal driving component 50 can also drive the second test piece to rotate in the horizontal plane.

[0065] For example, the horizontal driving component 50 can be an electric rotary platform capable of outputting horizontal rotational motion, and the electric rotary platform can be fixedly mounted to the second fixed component 40 by means of fasteners such as bolts. The second test piece is fixedly mounted on the output end of the electric rotary platform. On the basis of making the second test piece opposite to the first test piece, the electric rotary platform can be used to drive the second test piece to rotate in a horizontal plane.

[0066] It is worth noting that the first test piece and the second test piece mentioned above are one and the other of the track 21 and the electromagnet 22, respectively. That is to say, when the measuring device disclosed in the present invention is actually used, the track 21 and the electromagnet 22 constituting the magnetic suspension component 20 include at least two installation methods, one of which is to install the track 21 on the first fixed component 30 and the electromagnet 22 on the output end of the horizontal driving component 50, and the other is to install the electromagnet 22 on the first fixed component 30 and the track 21 on the output end of the horizontal driving component 50. For example, the drawings of the present invention show a situation in which the electromagnet 22 is installed on the first fixed component 30 and the track 21 is installed on the output end of the horizontal driving component 50.

[0067] A plurality of vertical driving components 60 may be fixedly disposed on the stand 10. Specifically, each vertical driving component 60 may be fixedly mounted on a second mounting seat 16 corresponding thereto.

[0068] Each vertical drive component 60 is suitable for outputting reciprocating linear motion in the vertical direction. For example, the vertical drive component 60 can be a known electric push rod, a cylinder or a hydraulic cylinder that can output reciprocating linear motion. In addition, the output end of each vertical drive component 60 is respectively hingedly connected to the position corresponding to the different position of the second test piece in the second fixing assembly 40.

[0069] For example, refer to Figure 5 As shown, based on the fact that the track 21 and the electromagnet 22 used in a general maglev vehicle are roughly rectangular, on this basis, in order to better adjust the position of the second test piece relative to the first test piece, there can be four vertical drive components 60, and the output ends of the four vertical drive components 60 are respectively hingedly connected to the positions corresponding to the four different positions of the second test piece in the second fixed component 40. Among them, each vertical drive component 60 can be hingedly connected to the second fixed component 40 through a universal ball head 61, so as to maximize the degree of freedom of the second fixed component 40 under the action of multiple vertical drive components 60.

[0070] Based on the above settings, with the cooperation of multiple vertical driving components 60 and horizontal driving components 50, the first test piece and the second test piece can be switched between multiple relative position states obtained from the track spectrum, so as to more realistically simulate the relative position between the track 21 and the electromagnet 22 during the operation of the maglev vehicle. Among them, the relative position states at least include a parallel state in which the first test piece and the second test piece are parallel to each other along their extension directions and a non-parallel state in which they are not parallel to each other.

[0071] Specifically, assume that in the initial state, the first test piece installed on the first fixed component 30 and the second test piece installed on the horizontal driving component 50 are parallel to each other along their extension directions, as shown in Figure 1 . At this time, the purpose of keeping the track 21 and the electromagnet 22 in an ideal parallel state is achieved. On this basis, when it is necessary to switch the track 21 and the electromagnet 22 from the ideal parallel state to other relative position states, the second test piece is driven by the horizontal driving component 50 to rotate at a predetermined rotation angle in the horizontal plane. At the same time, some of the multiple vertical driving components 60 output linear motion upward or downward. For example, one, two or three of the vertical driving components 60 output linear motion upward or downward. Based on the fact that the output ends of the vertical driving components 60 are hinged to the positions corresponding to different positions of the second test piece in the second fixed component 40, therefore, when some of the vertical driving components 60 act, the gap size between the local part of the second test piece and the first test piece can be changed, so as to realize the deflection of the second test piece relative to the first test piece, thereby changing the relative position state of the first test piece and the second test piece. At this time, the purpose of keeping the track 21 and the electromagnet 22 in a non-parallel state is achieved. This design is beneficial to adjusting the relative position between the track 21 and the electromagnet 22 based on the relative position states obtained from the track spectrum.

[0072] It can be seen that the measuring device disclosed in the embodiment of the present invention can realize multiple relative position states between the track 21 and the electromagnet 22, including an ideal parallel state and an actual complex relative position, through the cooperation of the horizontal driving component 50 and multiple vertical driving components 60. This design enables the measuring device to simulate the complex relative position relationship between the track 21 and the electromagnet 22 in actual operation based on the track spectrum, thereby helping to more realistically measure the values and changes of the levitation force and the guiding force. Compared with the known measuring devices in the prior art, this measuring device not only improves the accuracy and reliability of the measurement results, but also can provide more comprehensive and actual operating condition data support for the optimal design and performance evaluation of the maglev system, which helps to improve the operating stability and safety of the maglev system.

[0073] In addition, by using the measuring device disclosed in the embodiments of the present invention, the gap between the track 21 and the electromagnet 22 can also be adjusted as needed. Specifically, when the first test piece and the second test piece are kept parallel, it is only necessary to control the synchronous output of the plurality of vertical driving components 60 to move linearly upward or downward, so that the second test piece can approach or move away from the first test piece while remaining parallel to the first test piece, thereby realizing the adjustment of the gap between the track 21 and the electromagnet 22.

[0074] In the embodiments of the present invention, the force detection component 70 is mainly used to measure the suspension force and the guiding force between the track 21 and the electromagnet 22 when the relative position between the track 21 and the electromagnet 22 is determined and the electromagnet 22 is in a continuous power-on state. The force detection component 70 can be arranged on the first fixing component 30.

[0075] Specifically, referring to Figure 4 As shown, the force detection component 70 can include a three-dimensional force sensor 71 and a test mounting base 72. Among them, the test mounting base 72 is suitable for mounting the first test piece. The three-dimensional force sensor 71 can be mounted on the first fixing component 30 and supported below the test mounting base 72.

[0076] With such a design, after the relative position between the track 21 and the electromagnet 22 is determined and the electromagnet 22 is powered on, the pulling forces of the first test piece in the vertical direction and the horizontal direction can be collected through the three-dimensional force sensor 71. Among them, the pulling force in the vertical direction can be regarded as the suspension force, and the pulling force in the horizontal direction can be regarded as the guiding force.

[0077] Furthermore, the force detection component 70 can be set to two, and the two force detection components 70 are arranged oppositely along the extending direction of the first test piece. By setting two force detection components 70, it is helpful to more accurately obtain the suspension force and the guiding force between the track 21 and the electromagnet 22 with the three-dimensional force sensors 71 of the two force detection components 70. Among them, when the force detection component 70 is two, the resultant force in the vertical direction collected by the three-dimensional force sensors 71 of the two force detection components 70 can be regarded as the suspension force, and the resultant force in the horizontal direction collected by the three-dimensional force sensors 71 of the two force detection components 70 can be regarded as the guiding force.

[0078] In some embodiments, referring to Figure 5 and Figure 6As shown, the second fixing component 40 can be a cross beam in the shape of an H to simplify the structure of the second fixing component 40 as much as possible. Moreover, a third mounting seat 41 for mounting the horizontal driving component 50 and a hinge seat 42 for hingedly connecting to the output end of the vertical driving component 60 are provided on the second fixing component 40. Among them, when there are four vertical driving components 60, the output ends of the four vertical driving components 60 are respectively hingedly connected to the four ends of the cross beam, so that the output ends of the four vertical driving components 60 correspond to four different positions of the second test piece.

[0079] In some embodiments, referring to Figure 4 As shown, the first fixing component 30 may include a linear motion mechanism 31 and a sensor mounting seat 32. The linear motion mechanism 31 can be arranged on the bench 10, especially on the first mounting seat 13 of the first connecting frame 12. And the linear motion mechanism 31 is adapted to output a reciprocating linear motion in the horizontal direction. For example, the linear motion mechanism 31 can be a known device such as a linear slide table.

[0080] The sensor mounting seat 32 is arranged at the output end of the linear motion mechanism 31, and the first test piece is mounted on the sensor mounting seat 32 by means of the force detection component 70. Specifically, the three-dimensional force sensor 71 of the force detection component 70 can be mounted on the sensor mounting seat 32. While realizing the mounting of the first test piece to the first fixing component 30, the three-dimensional force sensor 71 of the force detection component 70 can be smoothly used to detect the suspension force and the guiding force.

[0081] With such a design, the linear motion mechanism 31 can be used to drive the sensor mounting seat 32 together with the force detection component 70 and the first test piece to perform a reciprocating linear motion in the horizontal direction. So that when the first test piece and the second test piece are in an ideal parallel state, by making the first test piece move relative to the second test piece in the horizontal direction, the first test piece and the second test piece are misaligned in the parallel state, which is convenient for more intuitively measuring the guiding force between the two. And through the setting of the linear motion mechanism 31, it is beneficial to conveniently align the first test piece and the second test piece accurately.

[0082] On the other hand, the embodiments of the present invention also disclose a method for measuring the suspension force and guiding force of an electromagnet based on a track spectrum. This measurement method uses the above-mentioned measurement device. Specifically, this measurement method includes:

[0083] a. Install the first test piece and the second test piece.

[0084] Specifically: Install the first test piece on the first fixing component 30, specifically on the test mounting seat 72 of the force detection component 70 on the first fixing component 30; install the second test piece at the output end of the horizontal driving component 50 so that the first test piece and the second test piece face each other; wherein, the first test piece and the second test piece are respectively one of the track 21 and the electromagnet 22 and the other one.

[0085] b. Align the first test piece and the second test piece, and adjust the gap between the first test piece and the second test piece to the target gap. Wherein, aligning the first test piece and the second test piece means that the first test piece and the second test piece are parallel up and down, and when observed from the vertical projection direction, their axes completely coincide on the vertical projection plane.

[0086] Specifically: First, drive the first test piece parallel to the second test piece to move horizontally along the horizontal direction by the linear motion mechanism 31 in the first fixing component 30 until the axes of the first test piece and the second test piece completely coincide on the vertical projection plane, so as to align the first test piece and the second test piece; subsequently, control the multiple vertical driving components 60 to synchronously output linear motion upward or downward, so that the second test piece approaches or moves away from the first test piece in a state parallel to the first test piece until the gap between the two meets the target gap.

[0087] Wherein, the target gap can be obtained from the design parameters of the maglev vehicle or the track spectrum. Wherein, in the state where the first test piece and the second test piece are aligned and the gap between the first test piece and the second test piece is adjusted to the target gap, the positions of the first test piece and the second test piece at this time can be used as the working origin of the horizontal driving component 50, the multiple vertical driving components 60, and the linear motion mechanism 31, so as to facilitate the subsequent actions of the horizontal driving component 50, the multiple vertical driving components 60, and the linear motion mechanism 31 based on the working origin, and to conveniently adjust the relative positions between the first test piece and the second test piece.

[0088] c. Based on various relative position states obtained from the track spectrum, adjust the relative positions between the first test piece and the second test piece to respectively obtain the levitation force and the guiding force of the first test piece and the second test piece in different relative position states.

[0089] Specifically, when it is necessary to measure the suspension force and guiding force when the first test piece and the second test piece are maintained in an ideal parallel state, the first test piece and the second test piece are kept in an ideal parallel state, and then the electromagnet 22 is powered on, and the corresponding suspension force and guiding force can be detected and obtained through the force detection component 70; correspondingly, when it is necessary to measure the suspension force and guiding force when the first test piece and the second test piece are maintained in a non-parallel state, first, based on the relative position state of the track 21 and the electromagnet 22 obtained from the track spectrum in the non-parallel state, and then through the cooperation of the horizontal driving component 50 and / or multiple vertical driving components 60, the relative positions of the first test piece and the second test piece are adjusted to meet the requirements of the corresponding relative position state in the track spectrum. On this basis, the electromagnet 22 is powered on, and the corresponding suspension force and guiding force can be detected and obtained through the force detection component 70.

[0090] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
