Description

Technical Field

[0001] The invention relates to the technical field of maglev rail transportation, and in particular to a parallel hybrid maglev support system. Background Art

[0002] With the acceleration of urbanization, the demand for urban rail transit is growing, and the traditional rail transit system is facing challenges in speed, comfort and environmental protection. As an emerging mode of transportation, magnetic levitation technology has gradually attracted attention due to its advantages such as non-contact, low friction and high speed.

[0003] At present, the more mature magnetic levitation technologies include conventional electromagnetic levitation, superconducting electric levitation and permanent magnetic levitation. Conventional electromagnetic levitation uses conventional magnets and guide rails as magnetic conductors. The suspension gap is about 10mm and the operating speed is usually 300-500km / h. It is suitable for inter-city and suburban transportation, but the suspension force is all provided by electromagnets, so the suspension energy consumption is relatively large. Superconducting electric levitation uses superconducting magnets and cryogenic technology to achieve suspension. The suspension gap is about 100mm and the maximum operating speed can reach 1000km / h, but the increase in investment in cryogenic systems leads to higher construction technology and costs. Permanent magnetic levitation technology uses special permanent magnetic materials to achieve suspension. It does not require any other power support and can achieve self-stabilizing suspension. However, the suspension gap cannot be adjusted and there are problems such as difficult guidance, which restricts the development of permanent magnetic levitation technology.

[0004] Hybrid magnetic levitation technology combines the advantages of conventional electromagnetic levitation and superconducting electric cyclone technology. It has a large suspension gap, and the train can run stably at high speeds and adapt to more complex road conditions. However, due to the magnetic field coupling between electromagnetics and permanent magnets, the system is more complicated, the stability of the magnetic field strength is difficult to ensure, and the suspension height is unstable, affecting the smoothness of the train operation. In addition, the addition of permanent magnetic suspension modules makes the control of the suspension system more complicated, and the suspension control is more complex.

[0005] Taking the hybrid suspension technology route is an effective way to solve some of the problems existing in the above-mentioned suspension methods, but the traditional suction-type permanent magnetic suspension faces problems such as limited applicable scenarios and flexibility, and magnetic locking. Summary of the invention

[0006] The purpose of the present invention is to provide a parallel hybrid magnetic levitation support system, in which the bogie is suspended above the permanent magnet track by the suspension force jointly generated by permanent magnets and electromagnets, thereby realizing support without mechanical contact, reducing maintenance and operation costs, improving operation quality, and reducing noise. The relatively independent parallel structure design of permanent magnets and electromagnets reduces the coupling between electromagnets and permanent magnets, which can effectively improve the flexibility of the suspension system and reduce the control difficulty of the system.

[0014] Preferably, the vehicle-mounted electromagnetic magnet group is composed of a plurality of unit electromagnets; the iron cores of the unit electromagnets are vertically arranged and aligned with the permanent magnetic material in the vertical magnetization direction of the permanent magnetic track.

[0015] Preferably, each unit electromagnet in the vehicle-mounted electromagnet group is embedded in a U-shaped magnetic conductive material.

[0016] Preferably, the electromagnetic coil wound on each of the unit electromagnets has the same size and number of turns.

[0017] According to the above technical solution, the parallel hybrid magnetic suspension support system in the present invention has the following features:

[0018] Beneficial effects:

[0019] 1. The bogie is suspended above the permanent magnetic track through the suspension force generated by permanent magnets and electromagnets, achieving non-mechanical contact support, reducing maintenance and operation costs, improving operation quality, and reducing noise;

DETAILED DESCRIPTION

[0033] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0034] In the present invention, unless otherwise stated, directional words contained in terms such as "up, down, left, right, front, back, inside, outside" merely represent the orientation of the terms in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the terms.

[0035] See also Figure 1-5 A parallel hybrid magnetic suspension support system is shown, comprising a U-shaped box beam 12 and an I-shaped bogie 13 embedded in the box beam 12 and movable along the length direction of the box beam 12; a permanent magnetic track 8, 21 is fixedly connected to the upper plate and the lower plate of the bogie 13 on both sides of the box beam 12, and a plurality of hybrid suspension points are symmetrically arranged on the lower plate of the bogie 13, each of which comprises a vehicle-mounted permanent magnetic group 4, 7, 16, 19 and a vehicle-mounted electromagnetic magnetic group 3, 9, 15, 20 arranged in parallel; there is a mutual attraction between the permanent magnetic tracks 8, 21 and the vehicle-mounted permanent magnetic groups 4, 7, 16, 19, and there is an attraction or repulsion between the permanent magnetic tracks 8, 21 and the vehicle-mounted electromagnetic magnetic groups 3, 9, 15, 20.

[0036] Through the implementation of the above technical solutions, the bogie 13 is suspended above the permanent magnet rails 8 and 21 through the suspension force jointly generated by permanent magnets and electromagnets, achieving non-mechanical contact support, reducing maintenance and operation costs, improving operation quality, and reducing noise; the relatively independent parallel structure design of permanent magnets and electromagnets reduces the coupling between electromagnets and permanent magnets, which can effectively improve the flexibility of the suspension system and reduce the control difficulty of the system; the special electromagnet structure corresponding to the design of the HALBACH group number can greatly improve the suspension efficiency of the entire suspension system and reduce the suspension energy consumption; the basic suspension force is provided by the mutual attraction between the on-board permanent magnets and the permanent magnet rails 8 and 21, and then the on-board electromagnetic groups 3, 9, 15, and 20 dynamically adjust the current to achieve more precise suspension control; this hybrid method can not only effectively respond to the suspension requirements under different loads and operating conditions, but also provide redundancy protection in the event of a fault, ensuring the safety and reliability of the system.

[0037] In this embodiment, a plurality of guide wheels 1, 2, 5, 6 are installed on the left and right sides of the upper plate of the bogie 13, and a plurality of anti-collision wheels 10, 14, 17, 22 are installed on the left and right sides of the lower plate of the bogie 13.

[0038] See also Figure 1 and Figure 4 As shown, the guide wheels 1, 2, 5, 6 are installed on the upper plate of the bogie 13 through the wheel frame, and are symmetrically arranged on the left and right sides, playing the role of guiding and limiting the bogie 13. The guide wheels 1, 2, 5, 6 can be made of rubber wheels or some other materials to make them have higher wear resistance and quietness.

[0039] The anti-collision wheels 10, 14, 17, 22 are installed on the lower plate of the bogie 13 through the wheel frame, and are symmetrically arranged on the left and right sides, playing the role of anti-collision of the linear motor mover 18 and the permanent magnetic rails 8, 21. In the event of suspension failure, the safety of the linear motor mover 18 and the permanent magnetic rails 8, 21 can be protected. Of course, anti-collision copper blocks can also be installed on both sides of the vehicle-mounted magnetic rails. The anti-collision wheels 10, 14, 17, 22 can be made of rubber wheels or other materials to have higher wear resistance and quiet performance.

[0040] In this embodiment, a linear motor mover 18 is installed below the lower plate of the bogie 13 , and a linear motor induction plate 11 used in conjunction with the linear motor mover 18 is installed above the bottom plate of the box beam 12 .

[0041] Through such an arrangement, the linear motor mover 18 and the linear motor induction plate 11 interact with each other to provide the bogie 13 with forward drive power.

[0042] In this embodiment, in order to achieve accurate control of the suspension gap, a plurality of position sensor assemblies 23, 24, 25, 26 are also installed above the lower plate of the bogie 13. For example, in one embodiment, the position sensor assemblies 23, 24, 25, 26 are arranged above the lower plate of the bogie 13 near the center beam of the bogie 13, and a plurality of them are arranged symmetrically on the left and right. Figure 4 As shown, the position sensor components 23, 24, 25, and 26 are used to detect the suspension gap and the acceleration of the system, and the collected data is acquired and processed by the controller, thereby adjusting the current flowing through the vehicle-mounted electromagnetic magnetic group 3, 9, 15, and 20, thereby dynamically adjusting the suspension gap, so that the entire system can maintain an efficient operating state when facing various operating conditions and disturbances.

[0043] By accurately adjusting the current of the electromagnetic magnetic group through the position sensor components 23, 24, 25, and 26, the present invention can effectively cope with different loads and external environmental changes and ensure the operating safety of the system under normal and fault conditions.

[0044] In this embodiment, steel plates are fixed on both sides of the box beam 12, and the permanent magnetic tracks 8 and 21 are fixed on the bottom side of the steel plates. Through such an arrangement, a mounting method of the permanent magnetic tracks 8 and 21 is provided.

[0045] In this embodiment, the permanent magnet tracks 8 and 21 are made of multiple groups of HALBACH array permanent magnet materials. The on-board permanent magnet groups 4, 7, 16, and 19 are made of multiple groups of HALBACH array permanent magnet materials; the arrangement of the permanent magnet materials in the on-board permanent magnet groups 4, 7, 16, and 19 is the same as that in the permanent magnet tracks 8 and 21.

[0046] In one embodiment, see Figure 3 As shown, the permanent magnetic tracks 8 and 21 on one side are made of 5 groups of HALBACH array permanent magnetic materials, and the directions from the outside to the inside are the first upper unit magnetic block 801a, the second upper unit magnetic block 801b, the third upper unit magnetic block 801c, the fourth upper unit magnetic block 801d and the fifth upper unit magnetic block 801e, and the magnetization direction is as follows Figure 3 As shown by the arrows in the figure; the on-board permanent magnet groups 4, 7, 16, and 19 are also made of 5 groups of HALBACH array permanent magnet materials, and the direction from the outside to the inside is the first lower unit magnetic block 701a, the second lower unit magnetic block 701b, the third lower unit magnetic block 701c, the fourth lower unit magnetic block 701d and the fifth lower unit magnetic block 701e, and the magnetization direction is as shown in FIG. Figure 3As shown by the arrows in the figure, the unit magnetic blocks on the permanent magnetic rails 8 and 21 correspond to the unit magnetic blocks on the vehicle-mounted permanent magnetic groups 4, 7, 16, and 19 in a one-to-one manner in the vertical direction. Through such an arrangement, the suction provided by the reinforced side of the HALBACH magnetic group is used as the basic load suspension force, which can greatly improve the load capacity of the support system, have a higher floating weight ratio and suspension efficiency, and automatically align without adding a guide module.

[0047] Of course, in addition to using 5 groups of HALBACH arrays, the on-board permanent magnet groups 4, 7, 16, and 19 can also be rotating 7 groups of HALBACH arrays.

[0048] In this embodiment, the vehicle-mounted electromagnetic magnet group 3, 9, 15, 20 is composed of a plurality of unit electromagnets; the iron core of the unit electromagnet is vertically arranged and aligned with the permanent magnetic material of the permanent magnetic track 8, 21 in the vertical magnetization direction. When the permanent magnetic track 8, 21 is made of 5 groups of HALBACH array permanent magnetic materials, see Figure 2 As shown, each vehicle-mounted electromagnetic magnet group 3, 9, 15, 20 is composed of three rectangular unit electromagnets, namely three iron cores and a first unit electromagnet coil 901a, a second unit electromagnet coil 901b and a third unit electromagnet coil 901c wound on the iron cores. The three iron cores are respectively aligned in the vertical direction with the first upper unit magnetic block 801a, the third upper unit magnetic block 801c and the fifth upper unit magnetic block 801e.

[0049] like Figure 2 As shown, the suspension force of each mixed suspension point can be adjusted by controlling the current magnitude of the three unit electromagnets, and the magnetic field direction of the electromagnet can also be realized by controlling the current direction of the electromagnet, specifically as follows: by controlling the current direction of the first unit electromagnet coil 901a, the magnetization direction of the corresponding electromagnet can be made the same as or opposite to the magnetization direction of the first upper unit magnetic block 801a; by controlling the current direction of the second unit electromagnet coil 901b, the magnetization direction of the corresponding electromagnet can be made the same as or opposite to the magnetization direction of the third upper unit magnetic block 801c; by controlling the current direction of the third unit electromagnet coil 901c, the magnetization direction of the corresponding electromagnet can be made the same as or opposite to the magnetization direction of the fifth upper unit magnetic block 801e.

[0050] In this embodiment, each of the unit electromagnets in the vehicle-mounted electromagnet groups 3, 9, 15, 20 is embedded in the U-shaped magnetic conductive material 901. Figure 2As shown, the three rectangular unit electromagnets are embedded in the U-shaped magnetic conductive material 901, which can effectively focus the magnetic field generated by the electromagnets and reduce magnetic flux leakage, so that the magnetic force of the vehicle-mounted electromagnetic magnetic group 3, 9, 15, and 20 is more concentrated, and also plays a role in structural reinforcement. By fixing the electromagnets together, the durability and overall stability of the electromagnetic magnetic group are improved, the maintenance requirements are simplified, and the service life of the system is extended.

[0051] In this embodiment, the size and number of turns of the electromagnetic coil wound on each of the unit electromagnets are the same. This arrangement facilitates global regulation. In addition, each permanent magnet in the on-board permanent magnet groups 4, 7, 16, 19 is of the same size, and each permanent magnet in the permanent magnet tracks 8, 21 is also of the same size.

[0052] In this embodiment, the box beam 12 is made of welded steel or cast concrete, forming a U-shaped structure, fixed on the horizontal ground or fixed on a concrete cast column. The bogie 13 is made of aluminum profiles or steel structure, forming an I-shaped structure, and embedded in the box beam 12.

[0053] See also Figure 5 When the system is operating normally, the four on-board permanent magnet groups 4, 7, 16, and 19 shown in the figure generate a mutually attractive magnetic force with the symmetrical permanent magnet rails 8 and 21 on both sides through the principle of attraction between opposite magnetic poles, which not only provides an upward suspension force but also maintains lateral guiding stability.

[0054] At the same time, the algorithm is used to control the current direction and magnitude of the on-board electromagnetic magnetic groups 3, 9, 15, and 20 in real time, thereby adjusting the suspension force of each suspension point. The suspension force F of each mixed suspension point is F C +F P ,like Figure 5 As shown, F C is the electromagnetic force, which can be positive or negative. When the corresponding three unit electromagnets are all positive currents, F C Take +, when the corresponding three unit electromagnets are all positive current F C Take -, F p is the permanent magnetic attraction, is +, when the suspension force is equal to the gravity of the bogie 13, that is, F=mg (m is the suspension mass of a single point), the bogie 13 realizes non-mechanical contact operation, thereby effectively avoiding direct friction between the wheel and the rail. This not only significantly reduces the wear of parts, but also extends the overall service life of the system, and reduces the maintenance costs caused by frequent repairs and replacement of parts. In addition, since the system has no mechanical contact, the operating noise is also greatly reduced, further improving the riding comfort of passengers and improving energy efficiency.

[0055] The parallel hybrid magnetic suspension support system of the present invention has a compact design and a simple structure, and can realize the suspension and guidance functions of the vehicle. Under normal operating conditions, the on-board permanent magnetic groups 4, 7, 16, and 19 provide the main suspension force, while the on-board electromagnetic magnetic groups 3, 9, 15, and 20 assist in controlling the suspension height and stability by adjusting the current, thereby achieving a "zero-power" suspension effect and significantly reducing energy consumption.

[0056] At the same time, the hybrid magnetic suspension support system of the present invention eliminates the mechanical contact between the wheel and the rail, reduces friction and wear, prolongs the service life of the system, and improves the comfort of passengers.

[0057] The present invention is not only applicable to urban rail transit, but can also be extended to other fields such as high-speed railways, industry, and medical treatment. By improving suspension efficiency, reducing maintenance costs and noise pollution, the present invention provides a more efficient and environmentally friendly solution for future urban rail transit.

[0059] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.
