Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to specific embodiments of the present invention and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the related scheme, the suspension modes of the high-speed magnetic suspension train have various modes, and the main established operation modes are as follows: the Shanghai Pudong airport is usually conductive magnetic suspension type, the long sand and Beijing S1 line F rail type, the Japanese sorbitol line low temperature superconductive suspension type and the like. The development process includes high temperature superconductive magnetic suspension with southwest cross-section mainly and electric suspension of several permanent magnets in the United states.
The common conductive magnetic levitation technology (EMS for short) is to suspend the car body by utilizing the attraction force between the controllable direct current magnets at two sides of the levitation frame and the guide rail, and the levitation magnets need to be electrified with direct current; the low-temperature superconducting electric levitation technology (EDS for short) is to levitate a car body by utilizing acting force generated by a superconductor arranged on the car body and magnetic induction coils at two sides of a track; the permanent magnet electric suspension technology is that a permanent magnet is arranged at the lower part of the vehicle body, and the vehicle body is suspended by the repulsive force generated by the permanent magnet and the arc-shaped non-ferromagnetic track below in the moving process.
The common-conduction magnetic levitation technology is widely applied, and particularly, the middle-low-speed magnetic levitation scheme mostly adopts the common-conduction magnetic levitation technology. At present, an F-rail scheme is adopted for suspending a running low-speed magnetic levitation line in China, and the F-rail is utilized to generate levitation force and guiding force. But the normal conductive magnetic suspension mode utilizes the electromagnetic force of a conductor to control the suspension gap, the working suspension gap is small, the control precision requirement is high, the system redundancy is small, the F rail can provide limited guiding force, the F rail is not suitable for the higher-speed magnetic suspension operation, and the energy consumption is too large. The electric suspension technology adopts the superconducting coil to provide suspension force, so that the system stability is high, but the cost is high, and the construction difficulty is high.
The permanent magnet suspension technology can provide suspension force without electrifying, and saves energy, but the suspension clearance cannot be controlled because the permanent magnet suspension is passive suspension, the system damping is small, and the shake is larger.
Considering the advantages and disadvantages of the magnetic levitation schemes of the constant-conductivity magnetic levitation technology, the F-rail scheme adopted by the low-speed magnetic levitation line levitation, the permanent magnetic levitation technology and the electric levitation technology, the scheme of the invention provides a magnetic levitation train and a control method thereof, in particular to a permanent magnetic electromagnetic hybrid levitation vehicle system (namely a hybrid magnetic levitation vehicle system) and a control method thereof.
According to an embodiment of the present invention, there is provided a magnetic levitation train including: linear motor unit, vehicle body 2, and magnetic levitation unit.
The linear motor unit is arranged at the top of the vehicle body 2 and can provide upward normal force by utilizing a normal-conduction magnetic levitation technology.
The number of the magnetic suspension units is two, and the two groups of the magnetic suspension units are symmetrically arranged at the bottom of the vehicle body 2. And each group of magnetic suspension units provides upward suspension force by utilizing a low-temperature superconducting electric suspension technology. The body 2 is made to perform a levitation operation by the normal force and the levitation force.
In the magnetic levitation train provided by the scheme of the invention, a permanent magnet long stator synchronous motor is paved at the upper part of a line along the track, a permanent magnet rotor is positioned at the top of a running vehicle, the suction force between the iron core of the long stator synchronous linear motor and the permanent magnet rotor on the vehicle is fully utilized to provide an upward normal force, namely, the normal force is provided by utilizing a normal conduction magnetic levitation technology (EMS). In addition, a non-ferromagnetic material (such as aluminum, copper and the like) is paved on the track as the track and is positioned below the running vehicle, after the running vehicle, namely when the running vehicle runs, the conductor cuts the magnetic field of the permanent magnet to provide upward levitation force, namely the low-temperature superconducting electric levitation technology (EDS for short) is utilized to provide upward levitation force, so that the running vehicle is levitated under the combined action of normal force and levitation force.
In some embodiments, the linear motor unit includes: a permanent magnet synchronous motor with an iron core. The permanent magnet synchronous motor includes: a linear motor stator and a linear motor rotor. The linear motor stator is arranged above the running line of the magnetic suspension train. The linear motor rotor is arranged at the top of the vehicle body 2.
In some embodiments, the linear motor stator includes: a stator core 1 and a stator coil provided on the stator core 1. The stator core 1 and the stator coil form a normally conductive electromagnetic module. The number of the normally conductive electromagnetic modules is two or more than two groups. Two or more groups of the normally conductive electromagnetic modules are symmetrically arranged along the running line of the magnetic suspension train.
In the scheme of the invention, the linear motor stator consists of two or more groups of longitudinal iron cores and energizing coils, and the iron cores are symmetrically arranged left and right relative to the central line of the vehicle body. Compared with other magnetic suspension systems adopting coreless synchronous motors, the magnetic suspension system adopting the coreless permanent magnet synchronous motor greatly improves the motor efficiency, reduces the electric energy consumption of the suspension system and the driving system, and reduces the running cost.
In some embodiments, an adjustment mechanism 9 is provided on the linear motor mover 8. During operation of the magnetic levitation train, the adjusting mechanism 9 can adjust the air gap of the linear motor unit to dynamically maintain the air gap of the linear motor unit within a set air gap range.
In the scheme of the invention, an adjusting mechanism 9 is arranged on the linear motor rotor 8. The adjustment mechanism 9 ensures that the linear motor air gap is maintained dynamically at a relatively constant interval while the vehicle is in operation. Therefore, the linear motor air gap adjusting mechanism is added, and the defect that the permanent magnet passive suspension type suspension air gap cannot be actively controlled is overcome.
In some embodiments, the linear motor unit, together with the two groups of magnetic levitation units, forms a triangular constraint structure for the vehicle body 2.
In the scheme of the invention, the linear motor stator 1 is a fixed part and is arranged above a vehicle running line, and the linear motor rotor is arranged at the top of the vehicle body 2. The top linear motor and the 2 groups of suspension modules at the lower part of the vehicle body form triangular constraint on the vehicle body, so that the operation is safer.
Compared with a rail holding type supporting structure of a low-speed maglev train in a related scheme, the mixed magnetic suspension supporting structure adopted by the scheme is more stable and reliable in a triangular suspension mode, the mixed magnetic suspension supporting structure fully absorbs the advantages of an EDS suspension system and an EMS suspension system, most of bearing capacity required by suspension is provided by the EDS suspension system, the energy consumption of the maglev train and the requirement on rail precision are reduced, a suspension air gap is increased, damping required for improving suspension performance is mainly provided by the EMS suspension system, and excellent control performance of the EMS suspension system is exerted.
In some embodiments, the two groups of magnetic levitation units have the same structure, and each group of magnetic levitation units comprises: the device comprises a first magnetic suspension module and a second magnetic suspension module. The first magnetic suspension module is arranged at the bottom of the vehicle body 2. The second magnetic suspension module is arranged on a track where the magnetic suspension train is located.
Wherein, first magnetic levitation module includes: the permanent magnet 5 is suspended. The second magnetic levitation module includes: and a levitation guide 7.
In the scheme of the invention, the levitation permanent magnet 5 is arranged below the vehicle body 2, and is right above the levitation guide rail 7 and is bilaterally symmetrical relative to the center line of the vehicle body. The train passes through an EDS suspension system under the train body, and the generated repulsive force provides suspension force and guiding force required by running.
In the scheme of the invention, when the vehicle is in a static state and a low-speed running state, the repulsive force and the guiding force generated by the EDS suspension system are small, so that the support wheels are required to support, and the guiding wheels are required to guide. The EDS levitation system can generate sufficient levitation force when the train is traveling at high speed, at which time the wheels are out of contact with the track. The vehicle controls levitation of the train by normal electromagnetic attraction generated by the EMS levitation system over the body of the vehicle.
In some embodiments, the magnetic levitation train further comprises: and a walking unit. The number of the walking units is the same as that of the magnetic suspension units.
Each group of the walking units comprises: a wheel support 3 and a guide wheel 4. The wheel bracket 3 is mounted at the bottom of the vehicle body 2. The number of the guide wheels 2 is two, and the two guide wheels 2 are arranged at the side part of the wheel bracket 3. The suspension permanent magnet 5 is arranged at the bottom of the wheel bracket 3.
In the solution of the present invention, the wheels 4 are mounted on both sides of the wheel support 3, the wheels 4 are used for guiding the vehicle running at low speed, and the wheels 4 are used as a backup means for preventing the derailment of the vehicle at high speed, and specifically, see the example shown in fig. 1.
In some embodiments, the magnetic levitation train further comprises: and a steering unit. The steering unit is arranged at the side of the vehicle body 2 and the running line of the magnetic levitation train.
The number of the steering units is two, and the two steering units are symmetrically arranged on two sides of the vehicle body 2.
In some embodiments, each set of the steering units comprises: a steering iron block 10 and a steering electromagnet 11, the steering iron block 10 being arranged on the side of the travelling path of the magnetic levitation train. The steering electromagnet 11 is disposed on a side wall of the vehicle body 2.
Referring to the example shown in fig. 1-4, the magnetic levitation train may include: the steering device comprises a linear motor stator, a vehicle body 2, a wheel bracket 3, guide wheels 4, a suspension permanent magnet 5, wheels 6, a suspension guide rail 7, a linear motor rotor 8, a rotor adjusting mechanism 9, a steering iron block 10 and a steering electromagnet 11.
In the scheme of the invention, the turning of the vehicle is performed by utilizing attractive force generated by the steering electromagnets 11 arranged on two sides of the vehicle body and the steering iron blocks 10 arranged on the line, so that the turnout and lane changing function of the vehicle is realized. When turning leftwards, the left electromagnet 11 of the vehicle is electrified, and when turning rightwards, the right electromagnet 11 of the vehicle is electrified, and the example shown in fig. 2 can be seen.
According to the magnetic levitation train provided by the scheme of the invention, the vehicle starts accelerating from a static state under the drive of the linear motor, and the stator comprises the iron core, so that normal suction force can be generated when current passes through the stator, and the linear motor rotor is pulled to vertically move upwards. At the same time, as the vehicle moves forward, the levitation module generates a vertical upward levitation force. When the sum of the normal suction force and the levitation force is equal to the gravity of the vehicle, the vehicle levitates. When the vehicle starts accelerating from rest, the levitation force and the normal suction force are small, the vehicle runs by virtue of the support of wheels, and the guide wheels guide; when the vehicle needs to turn and pass through the turnout, the suction force of the electromagnets and the steering iron blocks on two sides of the vehicle body is utilized to realize steering.
In the scheme of the invention, the permanent magnet passive suspension (EDS) and the electromagnetic suspension (EMS) are adopted to act on the vehicle body together, so that the suspension control technology difficulty, the engineering difficulty and the operation control difficulty are greatly reduced, and the construction cost of a single kilometer is greatly reduced. The permanent magnet passive suspension and the electromagnetic suspension are adopted to act on the vehicle body together, and compared with a single permanent magnet suspension scheme, the normal force of the linear motor provides certain vertical damping for the permanent magnet suspension, so that the system is more stable and riding is more comfortable. The permanent magnet passive suspension and the electromagnetic suspension are jointly acted on the vehicle body, so that the suspension gap is increased, the maximum suspension gap can reach 60mm, the suspension gap is far superior to 8-13mm of Shanghai magnetic suspension, the redundancy of the system is improved, and the speed per hour 603 km extreme value created in Japan can be exceeded theoretically.

first control scenario: and adjusting the normal force between the linear motor rotor and the linear motor stator in the linear motor unit by adjusting the height of the linear motor rotor in the linear motor unit relative to the top of the vehicle body (2).
