[0023] Figure 1 A cross-sectional schematic diagram of an ultra-high-speed magnetic levitation electromagnetic propulsion test system according to an embodiment of the present invention is shown.
[0024] like Figure 1As shown, an embodiment of the present invention provides an ultra-high-speed magnetic levitation electromagnetic propulsion test system, wherein the system includes a track beam, an energy device, a power device, a track, and a skid. The energy device supplies power to the power device through a cable network. The skid is used to carry a test load. The track beam includes a left track beam body, a middle track beam body, and a right track beam body. A first slot is provided between the left track beam body and the middle track beam body, and a second slot is provided between the middle track beam body and the right track beam body. The power device includes a long stator linear motor, which includes a mover magnet, a suspension induction unit, and a ground primary propulsion module. The mover magnet is arranged on the skid. Suspension induction units are provided on both side walls of the first slot and both side walls of the second slot. The left track beam body has a first protrusion, and the right track beam body has a second protrusion. Ground primary propulsion modules are provided on both sides of the first protrusion and both sides of the second protrusion. Suspension induction units are provided above and below the ground primary propulsion module on the first protrusion, and above and below the ground primary propulsion module on the second protrusion. Tracks are provided on the upper part of the first protrusion, the upper part of the second protrusion, and the upper part of the middle track beam body.
[0025] Through the above technical solution, tracks can be set on the left track beam body, the middle track beam body and the right track beam body of the track beam, and motors can be arranged at different track beam positions. Therefore, the test requirements of different test loads can be achieved on the same track topology only by replacing the skid car.
[0026] Specifically, there are 4 sets of motor equipment on the entire track beam (such as Figure 2 The primary propulsion module is located on the ground, with suspension induction plates installed above and below it. The top of the track beam is equipped with a permanent magnet track. The track has two channels (the first and second channels) in the middle, which only house the suspension induction plates.
[0027] The entire track beam has a symmetrical cross-section and can be divided into three parts: left, middle, and right. Figure 1 shown.
[0028] In this invention, the entire track, which can be kilometers long, is laid horizontally. Linear motors are used on the track to power the system. An energy device supplies power to the linear motors via a cable network. Through the principle of electromechanical energy conversion, the sled and test load are launched onto the track at high speed. The sled is the vehicle for the entire system's motion, supporting the test load and the linear motor's mover.
[0029] According to one embodiment of the present invention, the system further includes a high-temperature superconducting block material disposed at the bottom of the skid vehicle.
[0030] According to one embodiment of the present invention, the track is a permanent magnet track.
[0031] According to one embodiment of the present invention, the mover magnet is a superconducting magnet, a permanent magnet or an electromagnetic magnet.
[0032] According to an embodiment of the present invention, the suspension sensing unit is a suspension sensing plate.
[0033] The ultra-high-speed magnetic levitation electromagnetic propulsion test system of the present invention is described below with reference to examples.
[0034] Regarding propulsion and braking, the system utilizes a long-stator linear motor and a ground-based primary propulsion module. The primary propulsion coil within the module generates a traveling magnetic field, which interacts with the mover magnets on the sled (which can be superconducting magnets, permanent magnets, or electromagnetic magnets), generating thrust. Braking utilizes the motor's energy-consuming braking method to brake the sled while in motion, a concept not detailed here.
[0035] Regarding the principle of dynamic suspension, the system adopts electric suspension and lays a suspension induction plate. When the skid moves at high speed, the on-board mover magnet (which can be a superconducting magnet, permanent magnet, electromagnetic magnet or other magnetic source) passes over the suspension induction plate, generating induced eddy currents. The induced eddy current magnetic field interacts with the mover magnet magnetic field, generating suspension of the system (constrained both above and below) and guiding force, providing stability for the system.
[0036] Regarding the static suspension principle, when the sled is in a non-moving state, the system adopts a high-temperature superconducting pinning suspension form, and the track adopts a permanent magnet track (for example, permanent magnets can be laid on the track to obtain a permanent magnet track). The high-temperature superconducting block material on the vehicle interacts with it in a superconducting state to form a magnetic flux pinning force, providing the suspension force for the entire sled when it is stationary.
[0037] The following describes the testing process of the ultra-high-speed magnetic levitation electromagnetic propulsion testing system according to the present invention with reference to examples.
[0038] For test products with small size and mass (such as inertial navigation, etc.), only the equipment of the test system can be used. Figure 2 As shown in the figure. Since the test load is small in size and mass, the main mass of the system is still the lower skid bracket and the mover magnet (located at the bottom of the skid bracket), which makes the entire system have a small thrust eccentricity, effectively improving the test stability and reliability of the system. In this mode, the power supply of the four linear motors (looking down at the track) is shown in the figure. Figure 3 As shown, power can be supplied to motor 1 and motor 2.
[0039] For test objects with smaller size and larger mass (such as warheads), in order to avoid system instability caused by excessive system thrust eccentricity, the test load should not be placed on the top of the propulsion system. Therefore, the test load can be placed on the thrust center line of the linear motor, such as Figure 4 As shown. The center of the track can be used (there is a certain space between motor 2 and motor 3), where motor 2 and motor 3 are powered. The power supply of the four linear motors in this mode (looking down at the track) is shown as follows Figure 5 As shown, the motors 2 and 3 can be powered.
[0040] For test objects with larger size and mass (such as winged drones), since the test objects are relatively large, they can be placed on the top of the skid and track. They naturally have the characteristic of eccentric thrust. Therefore, two levitation magnets are added to the levitation slot below the track (such as Figure 6 As shown in the figure, the first is to lower the center of mass of the entire assembly, and the second is to provide vertical and guiding stiffness during the dynamic suspension process through the suspension magnet, further enhancing the safety and stability of the system. Due to the large mass of the test object, four sets of motors are used to power the system simultaneously to increase the total propulsion and braking capabilities of the system. The power supply of the four linear motors in this mode (looking down at the track) is shown as follows Figure 7 As shown, 4 motors can be powered at the same time.
[0041] For ultra-high-speed trains or maglev train systems, it is necessary to study the aerodynamics and its impact when two trains meet at high speed. For such test requirements, the system described in the present invention can be used to load two sets of train structure models on the left side (corresponding to the left track beam) and the right side (corresponding to the right track beam) to carry out split motion tests (test platform for dual-track applications). Figure 8 As shown. Different from the above mode, the split test mode is to run from two independent tracks to the middle (i.e., run from two directions to the middle), and reach the maximum test speed when moving to the middle, and collect data on pneumatics and other aspects. The power supply of the four linear motors in this mode (looking down at the track) is shown as follows Figure 9 As shown, four motors can be powered at the same time, wherein motor 1 and motor 2 have the same direction (forward), and motor 3 and motor 4 have the same direction (reverse).
[0042] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.
[0043] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0044] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.
[0045] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
