Description

Technical Field

[0001] This invention belongs to the field of electromagnet levitation testing, specifically involving a test bench for the interaction between a high-speed maglev transportation levitation electromagnet and a guide rail. Background Technology

[0002] Many studies in the high-speed maglev transportation industry are in the stage of tackling key scientific research problems. In particular, the working mechanism and engineering application technology of key subsystems are not yet perfect, and there is a lack of test platforms for local application conditions of key subsystems.

[0003] Chinese invention patent CN108983009A discloses an electromagnet static performance testing platform and test bench. This platform tests the static performance of electromagnets, including their electrical and electromagnetic characteristics under static conditions. Electrical characteristics include resistance, inductance, and withstand voltage at different temperatures; electromagnetic characteristics include magnetic induction intensity and electromagnetic force. It can monitor the electromagnet temperature rise in real time, enabling temperature testing and overheat protection. It can test the electromagnet deformation under operating conditions, allowing for electromagnet pre-deflection design. It can simulate train static and buoyancy conditions, testing the static performance of electromagnets under different operating conditions. It can automatically adjust the suspension gap via a hydraulic device, and automate the testing process through a host computer in the performance testing cabinet. It features convenient testing, high testing accuracy, and comprehensive testing items, and can serve as a test bench for the production quality inspection, routine testing, and scientific research of electromagnets in high-speed maglev systems. However, the current electromagnet static performance testing platform and test bench can only test the electromagnet performance under normal operating conditions, i.e., the relative position and attitude of the electromagnet and the long stator are fixed values. In actual operation, the smoothness of the track may be abnormal. These abnormalities can lead to instability in the dynamic process of vehicle operation, affecting passenger comfort, or even jeopardizing train safety. Therefore, there is an urgent need to develop a high-speed maglev transportation electromagnet-rail interaction test bench capable of simulating local track irregularities, providing the necessary experimental environment for studying the characteristics of electromagnetic levitation force and control systems. Summary of the Invention

[0004] The purpose of this invention is to provide a test platform for the interaction between a high-speed maglev train levitation electromagnet and a guide rail. This platform can simulate different track postures such as misalignment, lateral movement, rail gap, deflection, and angle of the long stator, and can test electromagnetic characteristics under different track postures and current conditions.

[0005] A test bench for the interaction between a high-speed maglev transportation levitation electromagnet and a guide rail includes a control and detection system, a support frame, and a long stator assembly and an electromagnet assembly mounted on the support frame.

[0006] The long stator assembly includes a long stator mounting frame and at least two long stator segments disposed on the long stator mounting frame. The position and orientation of at least one long stator segment are adjustablely fixed on the long stator mounting frame. By adjusting the height position of one long stator segment in the height direction of the long stator, a misalignment condition between the two long stator segments is simulated. By adjusting the front-to-back position of one long stator segment in the width direction of the long stator, a lateral movement condition between the two long stator segments is simulated. By adjusting the left-to-right position of one long stator segment in the length direction of the long stator, a rail gap condition between the two long stator segments is simulated. By adjusting the rotation of one long stator segment around the length direction and around the height direction of the long stator, a deflection condition of the long stator is simulated. By adjusting the rotation of one or two long stator segments around the width direction of the long stator, an angle is formed between adjacent long stator segments, simulating an angled condition between the two long stator segments.

[0007] The electromagnet assembly includes a movable component that moves along the length of the long stator assembly and an electromagnet disposed on the output end of the movable component. The electromagnet is disposed below the long stator. The movable component drives the electromagnet to move along the length of the long stator, thereby simulating the operation of a train.

[0008] The control and detection system includes a controllable power supply system connected to the electromagnet and a detection system for detecting the state of the electromagnet; the controllable power supply system is used to control the magnitude of the current input to the electromagnet, thereby controlling the electromagnetic force between the electromagnet and the long stator; the detection system is used to record the gap between the electromagnet and the long stator and the magnitude of the current input to the electromagnet.

[0009] Test the coupling electromagnetic characteristics of the electromagnet under different currents in normal track conditions or under track conditions of misalignment, lateral movement, rail gap, deflection and angle bending.

[0010] The coupling electromagnetic characteristics of the electromagnet during its movement were tested under normal track conditions or under conditions of track misalignment, lateral movement, rail gaps, deflection, and angle bending.

[0011] Furthermore, the long stator is configured as three segments. The first long stator is fixedly mounted on the long stator mounting bracket to simulate normal working conditions; the middle long stator has three degrees of rotational freedom; and the last long stator has three degrees of translational and three degrees of rotational freedom. This allows the long stator to exist under multiple different working conditions simultaneously. When multiple different working conditions exist on the track simultaneously, the relationship between electromagnetic force and current changes is tested, and the electromagnetic force change characteristics of the electromagnet under different working conditions on multiple tracks are analyzed.

[0012] Furthermore, at least two mounting blocks are spaced apart along the length of the end of the long stator away from the electromagnet, and the two ends of the mounting blocks are connected to the long stator mounting bracket by bolts.

[0013] Furthermore, shims are adjustable between the mounting block and the long stator mounting bracket. By adjusting the arrangement of the shims, the misalignment, deflection, and angle of the long stator can be simulated.

[0014] Furthermore, the size of the mounting hole on the long stator mounting bracket corresponding to the bolt connector is larger than the diameter of the bolt of the bolt connector, thereby adjusting the long stator in both length and width directions to simulate the lateral movement, rail gap, deflection, and angle of the long stator.

[0015] Furthermore, the mounting hole is a strip-shaped hole or an oblong hole.

[0016] Furthermore, the long stator mounting bracket is adjustable along the height direction on the bracket to adjust the gap between the long stator and the electromagnet.

[0017] Furthermore, the detection system includes a three-part force sensor and a gap sensor. The three-part force sensor is disposed between the electromagnet and the moving component and is used to connect the electromagnet and the moving component, and is used to detect the vertical levitation force, horizontal guiding force and longitudinal traction force of the electromagnet; the gap sensor is used to detect the gap between the long stator and the electromagnet.

[0018] Furthermore, the controllable power supply system includes an adjustable constant current source, which is used to adjust the magnitude of the current output to the electromagnet.

[0019] The present invention has the following beneficial effects:

[0020] It can simulate various track attitudes, and thus simulate working conditions such as track misalignment, lateral displacement, track gaps, deflection and angle bending.

[0021] The coupling electromagnetic characteristics of the electromagnet can be tested under normal or abnormal track conditions (the effects of different track attitudes and different current magnitudes on the system can be tested, and these effects may be interrelated, i.e., there is a coupling effect).

[0022] The coupling electromagnetic characteristics of the electromagnet during its movement can be tested under both normal and abnormal track conditions.

[0023] By simulating various operating conditions such as track attitude changes, levitation electromagnet movement, and levitation electromagnet current changes, the dynamic test environment of electromagnet and track required for the interaction of electromagnet with different currents and track under various operating conditions can be realized. This can serve as a platform to support the study of levitation electromagnet-track dynamics, provide favorable conditions for independent innovation research on core technologies of high-speed maglev, and achieve breakthroughs in levitation control and dynamics research.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Example 1

[0031] This embodiment discloses a test bench for the interaction between a high-speed maglev transportation levitation electromagnet and a guide rail, which includes a support 1 and a long stator assembly 2 and an electromagnet assembly 3 mounted on the support 1.

[0032] The long stator assembly 2 includes a long stator mounting frame 21 and at least two long stator segments 22 disposed on the long stator mounting frame 21. The position and orientation of at least one long stator segment 22 are adjustablely fixed on the long stator mounting frame 21. By adjusting the position and orientation of the long stator segment 22, the misalignment, lateral movement, track gap, deflection and angle of the long stator can be simulated.

[0033] A coordinate system is established with the length direction of the long stator as the X-axis, the width direction of the long stator as the Y-axis, and the height direction of the long stator as the Z-axis. The simulation conditions are as follows:

[0034] Misalignment: By adjusting the height position of one section of the long stator 22 in the Z direction, the misalignment condition between the two sections of the long stator 22 is simulated;

[0035] Lateral movement: By adjusting the front and rear positions of one of the long stator segments 22 in the Y direction, the lateral movement between the two long stator segments 22 is simulated;

[0036] Rail gap: By adjusting the left and right position of one of the long stators 22 in the X direction, the rail gap condition between the two long stators 22 can be simulated.

[0037] Deflection: The deflection condition of the long stator 22 is simulated by adjusting the rotation of one section of the long stator 22 around the X direction and the rotation around the Z direction.

[0038] Angle bending: By adjusting the rotation of one or two long stator segments 22 around the Y direction, an angle is formed between two adjacent long stator segments 22, simulating the angle bending condition of the two long stator segments 22.

[0039] The electromagnet assembly 3 includes a moving component 31 that moves along the length of the long stator assembly 2 and an electromagnet 32 ​​disposed on the output end of the moving component 31. The moving component 31 includes a horizontal guide rail 311 and a horizontal slide 312. The electromagnet 32 ​​is disposed on the horizontal slide 312. The moving component 31 also includes a traction component 313 disposed on the bracket 1. The winch on the traction component 313 is connected to the horizontal slide 312, that is, the electromagnet 32 ​​can move along the length of the long stator 22 to simulate the movement of the electromagnet 32 ​​along the length of the long stator 22, thereby simulating the operation of a train.

[0040] By controlling the current input to the electromagnet 32, the electromagnet 32 ​​interacts with the long stator 22 to form an electromagnetic force. The electromagnet 32 ​​is located below the long stator 22. After inputting current to the electromagnet 32, the magnetic pole surface of the electromagnet 32 ​​interacts with the functional surface of the long stator 22 to form a levitation force.

[0041] This embodiment also includes a control and detection system, which includes a controllable power supply system and a detection system. The controllable power supply system is connected to the electromagnet 32 ​​and is used to supply power to the electromagnet 32. By controlling the magnitude of the current input to the electromagnet 32, the electromagnetic force between the electromagnet 32 ​​and the long stator 22 is controlled. The detection system is used to record the gap between the electromagnet 32 ​​and the long stator and the magnitude of the current input to the electromagnet 32.

[0042] The high-speed maglev transportation levitation electromagnet and guide rail interaction test platform provided in this embodiment has the following functions:

[0043] First, it can simulate various track postures (misalignment, lateral movement, track gap, deflection, and angle change), thereby simulating all working conditions of the track;

[0044] Second, the coupling electromagnetic characteristics of electromagnet 32 ​​under different currents can be tested under normal or abnormal track conditions (testing the effects of different track attitudes and different current magnitudes on the system, which may be interrelated, i.e., there is a coupling effect).

[0045] Third, the coupling electromagnetic characteristics of electromagnet 32 ​​during its movement can be tested under normal or abnormal track conditions.

[0046] This embodiment simulates various operating conditions, including changes in track attitude, movement of the levitation electromagnet 32, and adjustments in the current of the levitation electromagnet 32. This provides a dynamic experimental environment for the interaction between the electromagnet 32 ​​and the track 22 under different currents and operating conditions. It can serve as a platform for studying the dynamics of the levitation electromagnet-track system, providing favorable conditions for independent innovation and research into core technologies of high-speed maglev. It also assists in levitation control and dynamics research, such as studying the electromagnetic force variation under different track attitudes, analyzing the electromagnetic force variation curves when the electromagnet 32 ​​passes through track irregularities such as misalignments and gaps, and studying the relationship between electromagnetic force and current magnitude.

[0047] Example 2

[0048] This embodiment is basically the same as Embodiment 1, except that the number of long stator components is changed. Specifically, the long stator 22 is provided with three segments: the first long stator 22 is fixedly mounted on the long stator mounting bracket 21; the middle long stator 22 has rotational degrees of freedom in the X, Y, and Z directions; and the last long stator 22 has translational degrees of freedom in the X, Y, and Z directions, as well as rotational degrees of freedom in the X, Y, and Z directions. This allows the long stator 22 to simultaneously exist under multiple different operating conditions, enabling the study of the electromagnetic force-current change relationship when multiple irregularities exist on the track, and the analysis of the electromagnetic force change characteristics of the electromagnet 32 ​​when passing through multiple track irregularities.

[0049] In this embodiment, the first-end long stator assembly 22 is fixedly mounted on the long stator mounting bracket 21. This means the first-end long stator assembly 22 remains stationary and operates under normal conditions, serving as a reference long stator for other long stators. It also provides normal operating conditions for the electromagnet 32 ​​at the beginning of its movement. As the electromagnet 32 ​​passes the middle and tail-end long stator assemblies, the power supply magnet 32 ​​experiences one or more normal or abnormal operating conditions along the track. By configuring the middle long stator assembly 22 to have rotational freedom in the X, Y, and Z directions, and the tail-end long stator assembly 22 to have translational and rotational freedom in the X, Y, and Z directions, various operating conditions can be effectively simulated, simplifying adjustment.

[0050] Example 3

[0051] This embodiment, based on Embodiments 1 and 2, provides a specific implementation method in which the position and orientation of the long stator 22 are adjustablely fixed on the long stator mounting bracket 21, thereby achieving the adjustment of the position and orientation of the long stator 22.

[0052] At least two mounting blocks 23 are spaced apart along the length of the end of the long stator 22 away from the electromagnet 32. The two ends of the mounting blocks 23 protrude from both sides of the width direction of the long stator 22. The two ends of the mounting blocks 23 are connected to the long stator mounting frame 21 by bolt connectors 24. The bolt connectors 24 include bolts 241, nuts 242 and washers 243. The screw head of the bolt 241 abuts against the mounting block 23. The screw passes through the mounting block 23 and the long stator mounting frame 21. Washers 243 and nuts 242 are provided at the position where the screw extends out of the long stator mounting frame 21. The mounting blocks 23 are made of non-magnetic material, which facilitates the stable fixing of the long stator 22 on the long stator mounting frame 21, ensuring the stability of the test, and also facilitates the position adjustment of the long stator 22.

[0053] In this embodiment, a shim 25 is adjustable between the mounting block 23 and the long stator mounting bracket 21. By adjusting the arrangement of the shim 25, the misalignment, deflection, and angle of the long stator can be simulated. Specifically:

[0054] When simulating the misalignment condition: by adding shims 25 of the same thickness between the two mounting blocks 23 of a long stator 22 and the long stator mounting bracket 21, the height of the long stator 22 is not the same as that of the adjacent long stator 22, so as to simulate the condition that there is misalignment between two adjacent long stators.

[0055] During the deflection simulation: a shim 25 of thickness N1 is added to the front side of the two mounting blocks 23 of a long stator 22, and a shim 25 of thickness N2 is added to the rear side of the two mounting blocks 23, where N1≠N2. This causes the long stator 22 to rotate around the X direction, thus simulating the condition where the long stator deflects around the X direction.

[0056] When simulating the angled working condition: a shim 25 of thickness N1 is added to the first end of a long stator 22 by mounting block 23, and a shim 25 of thickness N2 is added to the last end of a long stator 22 by mounting block 23, where N1≠N2. The long stator 22 is then rotated around the Y direction to simulate the working condition where the long stator pitches around the Y direction. At this time, an angle appears between two adjacent long stators 22.

[0057] It also simulates misalignment, deflection and angle working conditions: three abnormal working conditions are simulated by shims 25. It has the characteristics of simple structure and flexible adjustment.

[0058] In this embodiment, the size of the mounting hole 26 on the long stator mounting bracket 21 corresponding to the bolt connector 24 is larger than the diameter of the bolt of the bolt connector 24. This allows for adjustment of the long stator 22 in both length and width directions, simulating lateral movement, track gaps, deflection, and angle changes of the long stator. Specifically:

[0059] When simulating the lateral movement condition: by moving the long stator 22 along the Y direction, while moving the four bolts 241 along the Y direction of the mounting hole 26, and finally tightening the nut 242, the position of the long stator 22 in the Y direction is inconsistent with that of the adjacent long stator 22, so as to simulate the lateral movement condition of the two adjacent long stators.

[0060] When simulating the rail gap condition: by moving the long stator 22 along the X direction, while moving the four bolts 241 along the X direction of the mounting hole 26, and finally tightening the nut 242, the long stator 22 is spaced apart from the adjacent long stator 22 in the X direction, so as to simulate the condition where there is a rail gap between two adjacent long stators.

[0061] When simulating the deflection condition: by moving the mounting block 23 at the head end of a long stator 22 in the Y+ or Y- direction and the mounting block 23 at the tail end in the Y- or Y+ direction, the long stator 22 is made to rotate around the Z direction, so as to simulate the condition that the long stator is deflected in the Z direction.

[0062] Combined with the shim 25, it can simultaneously simulate working conditions as well as misalignment, deflection and angle working conditions; through the bolt connector 24 and its corresponding mounting hole 26, it can simulate a variety of abnormal working conditions, and also has the characteristics of simple structure and flexible adjustment.

[0063] The mounting hole 26 can be a strip-shaped hole or a waist-shaped hole. The strip-shaped hole allows the bolt 241 to move a large distance along the Y direction, while the waist-shaped hole allows the bolt 241 to move a small amount along the Y and X directions, thus adapting to different adjustment needs. The waist-shaped hole can also be connected to one end of the strip-shaped hole.

[0064] Example 4

[0065] This embodiment is based on embodiments 1 to 3, with the addition of a scheme to adjust the gap between the long stator and the electromagnet.

[0066] The long stator mounting bracket 21 is adjustable along its height on the support 1 to adjust the gap between the long stator 22 and the electromagnet 32. The support 1 includes a base 11 and six columns 12 located at the four corners and the center of the base 11. Linear guide rails 13 are provided on the four columns 12 at the four corners. Vertical support moving parts 211 are provided at both ends of the long stator mounting bracket 211, and sliders 212 that slide with the linear guide rails 13 are provided on both sides of the vertical support moving parts 211. The long stator mounting bracket 21 is mounted on the columns 12 via the linear guide rails 13 and the sliders 212. A lifting mechanism 27 is provided on the base 11, and the output end of the lifting mechanism 27 is fixedly connected to the vertical support moving parts 211 to adjust the height of the vertical support moving parts 211 and the long stator mounting bracket 21. Through the above arrangement, the height of the long stator 22 can be adjusted precisely and quickly.

[0067] Example 5

[0068] This embodiment adds a three-part force sensor 4 and a gap sensor to the control and detection system based on embodiments 1 to 4.

[0069] The control and detection system also includes a three-part force sensor 4 and a gap sensor. The three-part force sensor 4 is disposed between the electromagnet 32 ​​and the moving component 31 and is used to connect the electromagnet 32 ​​and the moving component 31. Two three-part force sensors 4 are spaced apart in the X direction. A single three-part force sensor 4 can simultaneously measure the vertical levitation force, horizontal guiding force and longitudinal traction force of the levitation electromagnet 32. At the same time, the three-part force sensor 4 can adapt to various attitude adjustment requirements such as changes in vertical gap, horizontal displacement and changes in the length of the stator of the levitation electromagnet 32.

[0070] The gap sensor is used to detect the gap between the long stator 22 and the electromagnet 32; the control and detection system can collect physical quantities such as electromagnetic force and gap.

[0071] Example 6

[0072] This embodiment further improves the controllable power supply system based on embodiments 1-5. The controllable power supply system includes an adjustable constant current source, which can adjust the current output to the electromagnet 32. The adjustable constant current source directly controls the input current to the electromagnet 32. The adjustable constant current source is an externally input AC380V, three-phase five-wire power supply with a total power of 50 kW, capable of outputting 0-100A, DC0-500V current to the levitation electromagnet 32 ​​to generate electromagnetic levitation force.

[0073] Example 7

[0074] This embodiment provides a test method for the interaction between a levitation electromagnet and a guide rail in high-speed maglev transportation. Using the test bench for the interaction between a levitation electromagnet and a guide rail described in Embodiments 1-6, various track attitude conditions can be simulated, including simulations of stator misalignment, lateral displacement, rail gaps, deflection, and angle bending. Furthermore, electromagnetic characteristics under track irregularities and current conditions can be studied. Specifically:

[0075] Based on the long stator assembly 2, the control and detection system and the controllable power supply system, the characteristics of the levitation magnetic field and the change curve of the electromagnetic force were tested under different orbital attitude conditions.

[0076] Based on the long stator assembly 2, the control and detection system and the controllable power supply system, the characteristics of the levitation magnetic field and the change curve of the electromagnetic force were tested under different current conditions.

[0077] Based on the long stator assembly 2, the control and detection system and the controllable power supply system, the characteristics of the levitation magnetic field and the change curve of the electromagnetic force were tested under different track attitudes and different current coupling conditions.

[0078] Based on the long stator assembly 2, the moving assembly 31, the control and detection system, and the controllable power supply system, the influence of the irregularity of the long stator 22 on the electromagnetic characteristics is analyzed by moving the electromagnet 32 ​​under different track attitudes and different current magnitudes.
