[0042] The specific implementation of the embodiment of the utility model is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the utility model, and is not used to limit the embodiment of the utility model.

[0043] In the embodiments of the present utility model, unless otherwise specified, directional words such as "up, down, left, right" generally refer to the directions or positional relationships shown in the accompanying drawings, or the directions or positional relationships in which the utility model product is usually placed when in use.

[0044] The terms “first”, “second”, “third”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0045] The terms "parallel", "vertical", etc. do not mean that the components must be absolutely parallel or vertical, but can be slightly tilted. For example, "parallel" only means that its direction is more parallel than "vertical", and does not mean that the structure must be completely parallel, but can be slightly tilted.

[0046] The terms "horizontal", "vertical", "overhanging" and the like do not mean that the components are required to be absolutely horizontal, vertical or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0047] In addition, the terms "roughly" and "basically" are intended to explain that the relevant content does not require absolute precision, but can have certain deviations. For example, "roughly equal" does not only mean absolute equality. Since it is difficult to achieve absolute "equality" in actual production and operation, there are generally certain deviations. Therefore, in addition to absolute equality, "roughly equal" also includes the above-mentioned situation with certain deviations. Taking this as an example, in other cases, unless otherwise specified, the terms "roughly" and "basically" have similar meanings to the above.

[0048] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] Support seat 1;

[0052] A mounting plate 2 for accommodating a magnetic track 101, wherein the mounting plate 2 is rotatably disposed on the support seat 1 through a supporting rotating mechanism 3, and a position adjusting and fixing mechanism 4 is disposed on the mounting plate 2, wherein the position adjusting and fixing mechanism 4 is used to fix the corresponding magnetic track 101 and adjust the height of the corresponding magnetic track 101 on the mounting plate 2;

[0053] A three-dimensional angle adjustment mechanism 5 is arranged on the support base 1 through a height adjustment mechanism 6. A permanent magnet array 102 and a sensor 7 are arranged on the three-dimensional angle adjustment mechanism 5. The permanent magnet array 102 is located above the corresponding magnetic track 101. The three-dimensional angle adjustment mechanism 5 can adjust the three-dimensional angle of the permanent magnet array 102 relative to the magnetic track 101. The sensor 7 is used to measure the suspension force and lateral force exerted on the permanent magnet array 102.

[0054] Specifically, in the present embodiment, the support seat 1 plays a supporting and fixing role, and its specific structure can be set according to actual needs, but it is necessary to ensure that it has a certain structural strength and a small volume; in addition, the magnetic track 101 can be installed in the mounting disk 2 (the shape of the magnetic track 101 is matched with the accommodating space in the mounting disk 2), and a position adjustment fixing mechanism 4 is provided on the mounting disk 2, through which the position adjustment fixing mechanism 4 can not only realize the position fixation of the magnetic track 101 on the mounting disk 2, but also realize the adjustment of the fixed height of the magnetic track 101; secondly, a three-dimensional angle adjustment mechanism 5 is provided on the support seat 1 through a height adjustment mechanism 6, and the height adjustment mechanism 6 can adjust the height of the three-dimensional angle adjustment mechanism 5 (i.e., the permanent magnet array 102) relative to the surface of the magnetic track 101, and the permanent magnet array 102 and the sensor 7 are installed on the three-dimensional angle adjustment mechanism 5 to adjust the three-dimensional spatial position angle of the permanent magnet array 102 and the sensor 7, so as to simulate the actual operation state of the permanent magnetic suspension rail transit through the change of the position and spacing between the permanent magnet array 101 and the magnetic track 101, so as to carry out accurate testing.

[0055] Furthermore, the support rotation mechanism 3 comprises:

[0056] A rotating shaft 31, wherein the rotating shaft 31 is vertically rotatably disposed on the supporting seat 1, and the top end of the rotating shaft 31 is fixed to the mounting plate 2, and rotates under the action of a driving force;

[0057] A plurality of bearings 32 are arranged on the support seat 1 in sequence from top to bottom, and the rotating shaft (31) is connected to each bearing 32.

[0058] like Figure 1-3 As shown, specifically, at least two bearings 32 are sequentially arranged on the support seat 1 from top to bottom, and the outer ring of the bearing 32 is fixed on the support seat 1, and the rotating shaft 31 passes through the bearing 32 to be connected with the inner ring of the bearing 32, thereby realizing the fixed rotation of the rotating shaft, and the bearings 32 are arranged at a certain distance, which can effectively ensure the rotation stability of the rotating shaft 31. The bottom end of the rotating shaft 31 can also be rotatably connected to the support seat 1 through the bearing 32 to reduce friction.

[0059] Furthermore, the test bench for simulating the magnetic track relationship of permanent magnetic suspension rail transit also includes:

[0060] A driving mechanism 8 , wherein the driving mechanism 8 is connected to the rotating shaft 31 and is used for generating the driving force.

[0061] Specifically, in this embodiment, the driving mechanism 8 is also arranged on the support seat 1; the driving mechanism 8 can be set as a driving motor. When the driving motor is used, the driving shaft of the driving motor is connected to the rotating shaft 31 through a reducer, and the rotating shaft 31 can be driven to rotate through the rotation of the motor; in addition, the driving shaft and the rotating shaft 31 of the driving mechanism 8 can also be provided with sprockets to realize power transmission through chains; in addition, the driving shaft and the rotating shaft 31 of the driving mechanism 8 can also be provided with pulleys to realize power transmission by means of belts.

[0062] Furthermore, the installation disk 2 includes:

[0063] The annular mounting base plate 21 has side plates 22 disposed opposite to the annular mounting base plate 21 . The annular mounting base plate 21 and the two side plates 22 form a receiving space to receive the magnetic rail 101 .

[0064] Specifically, in this embodiment, in order to reduce the overall volume of the device while ensuring that the suspension force and lateral force at different spacings can be tested, the mounting disk 2 is set to be circular, that is, it includes an annular mounting base plate 21 and two side plates 22, and the two side plates 22 are relatively arranged on the mounting base plate 21. Correspondingly, the magnetic track 101 arranged in the mounting disk 2 also constitutes a circular ring structure.

[0065] Furthermore, the position adjustment and fixing mechanism 4 comprises:

[0066] A plurality of first bolts 41 are arranged at intervals on the annular mounting base plate 21, wherein the first bolts 41 are in contact with the bottom ends of the corresponding magnetic rails 101, and the height of the corresponding magnetic rails 101 relative to the annular mounting base plate 21 is adjusted by rotation;

[0067] A plurality of second bolts 42 are disposed on the side plate 22 in pairs and are in contact with the corresponding side walls of the magnetic rail 101 . The corresponding magnetic rail 101 is clamped by two second bolts 42 that are rotated to opposite positions to fix the magnetic rail 101 .

[0068] Specifically, Figure 4 As shown, in this embodiment, the magnetic track 101 also includes multiple permanent magnets, and are arranged in a Halbach array to ensure the stability of the magnetic field on the surface of the magnetic track 101, and the magnetic track is fixed in a receiving cavity formed by a bottom pad and four limit plates vertically arranged on the edge of the bottom pad, so that when fixing the magnetic track and adjusting the position height of the magnetic track 101, the first bolt 41 and the second bolt 42 will not directly contact the permanent magnet, but will contact the magnetic track 101, thereby protecting the magnetic track 101 and making the magnetic track 101 modular, which is convenient for installation and disassembly.

[0069] In one embodiment, a plurality of threaded holes are arranged at intervals on the annular mounting base plate 21, so that the first bolt 41 can be rotated into any threaded hole. When the height of the magnetic rail 101 needs to be adjusted, the height of the magnetic rail 101 can be adjusted by rotating the first bolt 41 to tighten the bottom pad. Similarly, a plurality of threaded holes are arranged in parallel in the vertical direction at corresponding positions of the side plate 22, and the second bolt 42 is rotatably arranged in a threaded hole. When the magnetic rail 101 needs to be fixed, the second bolt 42 is rotated into the threaded hole of the corresponding height according to the installation height of the magnetic rail 101, so that the two opposite second bolts 42 respectively tighten the limit plates of the magnetic rail 101 to achieve stable fixation of the magnetic rail 101.

[0070] In another embodiment, a threaded hole matching the second bolt 42 is provided at the bottom end of the bottom pad, and the end of the second bolt 42 can be rotated into the threaded hole of the bottom pad; similarly, a threaded hole matching the first bolt 41 is provided on the limit plate, so that the ends of the first bolt 41 and the second bolt 42 are respectively located in the threaded hole of the corresponding limit plate and the threaded hole of the bottom pad, ensuring that the first bolt 41 and the second bolt 42 are in stable contact with the magnetic rail 101. In this way, a waist-shaped hole is vertically opened directly at the corresponding position of the side plate 22. At this time, the second bolt 42 is not connected to the side plate 22 by threads, and the second bolt 42 needs to be connected to the threaded hole on the limit plate of the corresponding magnetic rail 101. After tightening the second bolt 42, the nut of the second bolt 42 squeezes the side plate 22, thereby achieving stable fixation of the magnetic rail 101 and making adjustment more convenient.

[0071] Through the above-mentioned method, different heights and positions can be simulated to simulate the unevenness of the track 101, and to simulate ups and downs, sinking, floating, nodding, lateral movement, shaking head, rolling and other states, so as to achieve comprehensive simulation and testing; in addition, the second bolt 42 can also adjust the amplitude of the two excitation sources.

[0072] Furthermore, the three-dimensional angle adjustment mechanism 5 is a three-axis rotating table.

[0073] Specifically, in this embodiment, the three-dimensional angle adjustment mechanism 5 is set as a three-axis rotating table, which can realize the angle adjustment of the three angles of x, y, and z, that is, the three-dimensional angle adjustment of the permanent magnet array 102 relative to the surface of the magnetic track 101 is realized. The structure is simple and the control is precise. It can effectively simulate the changing state of the suspension force and the side deviation force between the permanent magnet array 102 and the magnetic track 101 when the lateral deviation of the maglev train is high in actual operation.

[0074] Furthermore, the sensor 7 is a three-axis sensor.

[0075] Specifically, in this embodiment, a three-axis sensor is used to detect the change state of the suspension force and the sideways force between the permanent magnet array 102 and the magnetic track 101 in real time, so as to provide data support for the subsequent structure and operation of the maglev train.

[0076] Furthermore, the height adjustment mechanism 6 comprises:

[0077] A guide rail 61 is vertically arranged on the support seat 1;

[0078] The slider 62 is slidably disposed on the guide rail 61 and moves up and down along the guide rail 61 . The three-dimensional angle adjustment mechanism 5 is disposed on the slider 62 .

[0079] Specifically, in this embodiment, the guide rail 61 is vertically arranged on the support seat 1, and a slider 62 is arranged on the guide rail 61. The slider 62 can move up and down along 61 to achieve the height adjustment of the three-dimensional angle adjustment mechanism 5 (ie, the permanent magnet array 102); specifically, a linear motor slider can be used.

[0080] In another embodiment, the height adjustment mechanism 6 can also be configured as a pneumatic cylinder, an electric cylinder, and a screw lifting mechanism.

[0081] Furthermore, the support seat 1 comprises: a first step surface 11 and a second step surface 12;

[0082] The height adjustment mechanism 6 is arranged on the first step surface 11;

[0083] The supporting rotation mechanism 3 is arranged on the second step surface 12 .

[0086] Specifically, in this embodiment, the permanent magnet array 102 and each magnetic track 101 are arranged in a Halbach array, which can ensure the stability of the magnetic field of the strong magnetic surface, thereby ensuring the accuracy of the data during the test. Among them, take the example of the permanent magnet array 102 and the magnetic track 101 both having five permanent magnets arranged in parallel (from left to right, the first to the fifth blocks), as shown in FIG. Figure 4As shown, the magnetization directions of the permanent magnets are as follows: the first and fifth permanent magnets are magnetized from top to bottom, the second permanent magnet is magnetized from left to right, the third permanent magnet is magnetized from bottom to top, and the fourth permanent magnet is magnetized from right to left.

[0087] In another embodiment, the rotation speed of the mounting plate 2 and the height of the three-dimensional angle adjustment mechanism 5 can be adjusted through a control circuit and a button (the control circuit, power supply, etc. can be arranged inside the support base 1, and the button can be integrated on the support base 1) to improve the convenience of use.
