Description

Technical Field

[0001] This application relates to the field of magnetic levitation track inspection, and in particular to a magnetic levitation track inspection system. Background Technology

[0002] Maglev trains, as a type of train driven by electromagnetic propulsion, have the advantages of low energy consumption, high speed, and low noise and vibration compared to traditional trains. The basic principle of maglev trains is to be driven by the principle of magnetic field force. The train uses electromagnetic induction effect to induce eddy currents in aluminum or copper plates in the coil, thereby generating a reverse magnetic field and creating a reverse magnetic force, which makes it levitate on the track. At the same time, the electric motor uses electromagnetic force to make the vehicle move forward at high speed on the track to achieve the purpose of high-speed operation.

[0003] Due to the interaction between the maglev train and the track, the vibration coupling phenomenon between the train and the track is inevitable. This vibration coupling phenomenon will become more and more obvious during the long-term operation of the maglev train. In order to avoid this problem, it is necessary to set up inspection vehicles to inspect and analyze the track and find out where the problem is.

[0004] Therefore, how to achieve vibration coupling detection between trains and tracks is an important technical problem that urgently needs to be solved. Summary of the Invention

[0058] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application. It is understood that the accompanying drawings are provided for reference and illustration only, and are not intended to limit this application.

[0059] Existing intercity rail transit mainly relies on standard railways and urban railways. Maglev lines belong to urban railways. In maglev trains, vehicle coupling vibration can occur, and there may even be coupling vibration between the vehicle and the track 400, as well as between the vehicle and the bridge. This is due to the mutual vibration between the train and the track 400 during the high-speed operation of the maglev train. Generally, finite element analysis and modal analysis are needed to find out the cause of the track 400 coupling vibration.

[0060] Specifically, such as Figure 1 As shown, this application provides a magnetic levitation track 400 inspection system. The system mainly includes an inspection vehicle 100 and an inspection station 200. The inspection vehicle 100 inspects the track 400, and the main inspection content is the coupling resonance phenomenon of the track 400 caused by the movement between the inspection vehicle 100 and the magnetic levitation track 400.

[0061] The inspection device is installed on the magnetic levitation frame on the inspection vehicle 100. The magnetic levitation frame is located between the vehicle body and the track 400. The magnetic levitation train floats on the track 400 through the interaction of electromagnetic forces between the magnetic levitation frame and the track 400. It operates through the interaction of electromagnetic forces between the magnetic levitation frame and the track 400, achieving a completely different operating mode from conventional trains.

[0062] The inspection device is installed between the maglev frame and the vehicle body. Located at this position, the inspection device can directly detect the vibration data between the maglev frame and the vehicle body during the operation of the maglev train. This vibration data can be connected to the inspection station 200 via ground-to-ground communication. The inspection station 200 will store and analyze the vibration data. Multiple inspection stations 200 are set up, and the distance between each inspection station 200 is set according to different testing requirements. The spacing between inspection stations 200 is generally set to 50KM, 100KM, 200KM, etc. Different spacing of inspection stations 200 can be set according to the required precision. On the one hand, the setting of inspection stations 200 can receive the vibration data of track 400, which is convenient for detecting the vibration data of a line. On the other hand, the setting of inspection stations 200 can overcome the limitation of instrument size, which is convenient for data processing by equipment, and avoids the problem that the inspection vehicle 100 cannot carry the testing instruments.

[0063] This application assumes that multiple inspection stations 200 are set up by default, but the technical effect of this application can also be achieved when only one inspection station 200 is set up.

[0064] During the inspection process, track 400 needs to be inspected using an inspection device, which mainly includes:

[0065] The accelerometer mainly measures the acceleration of the maglev train per unit time. By analyzing the relationship between acceleration and time, the speed change of the maglev train can be plotted by the inspection station 200.

[0066] A displacement sensor is installed between the magnetic levitation frame and the vehicle body. A vibration frequency tester is also installed between the magnetic levitation frame and the vehicle body. Both the displacement sensor and the vibration frequency tester are used to test the vibration frequency state between the magnetic levitation frame and the vehicle body. In this testing process, the vibration frequency tester is mainly used for detection, while the displacement sensor mainly tests the vibration displacement between the magnetic levitation frame and the vehicle body. When the vibration frequency tester has a displacement testing function, the displacement sensor is mainly used to correct or fit the data of the vibration frequency tester, so that the measurement data is more accurate.

[0067] A control terminal is installed on the magnetic levitation frame. This control terminal is controlled by the inspection station 200 on the one hand, and is used to collect and control the data collected by the acceleration sensor, displacement sensor and vibration frequency tester on the other hand. The collected data is then transmitted to the inspection station 200 through the control terminal.

[0068] The inspection process includes three inspection phases: low-speed, medium-speed, and high-speed. The low-speed phase is primarily applicable to operating speeds of 50 km / h to 100 km / h; the medium-speed phase is primarily applicable to operating speeds of 100 km / h to 300 km / h; and the high-speed phase is primarily applicable to operating speeds of 300 km / h to 400 km / h.

[0069] The low-speed inspection phase primarily tests the degree of vibration frequency coupling between the maglev train and track 400 under low-speed operation. Due to the slow speed of the inspection vehicle 100, the vibration between the maglev frame, track 400, and vehicle body is not significant. Therefore, vibration excitation needs to be applied between the maglev frame and the vehicle body. This excitation is applied using a transient excitation method, specifically a rapid sinusoidal scanning excitation, supplied by a signal generator with an adjustable frequency. The excitation force is sinusoidal and can control the increase in vibration frequency at the inspection vehicle 100's operating speed to remain constant. The functional expression of the rapid sinusoidal scanning excitation force signal is:

[0070]

[0071] Among them, f 上 The initial frequency of vibration;

[0072] f 下 This is the frequency at which the vibration ends;

[0073] T is the oscillation period.

[0074] During the vibration application process, the vibration frequency tester, displacement sensor, and acceleration sensor on the inspection vehicle 100 all measure the vibration state of the maglev train. The measurement method involves generating a velocity change graph of the inspection vehicle 100 from the data collected by the acceleration sensor to understand the velocity change value of the inspection vehicle 100 per unit time. At the same time, a vibration frequency distribution graph is generated. By combining the velocity change graph and the vibration frequency distribution graph, the vibration coupling phenomenon can be analyzed. The precise coupling data of the inspection vehicle 100 at low speed can be obtained, which can help the corresponding engineers to improve the maglev train and avoid maglev train failure caused by coupling vibration at low speed.

[0075] During the medium-speed inspection phase, the main test is the degree of coupling between the maglev train and the vibration frequency of the track 400 under medium-speed operation. The inspection vehicle 100 operates at medium speed, and the acceleration sensor, displacement sensor and vibration frequency tester on the inspection device all detect the vibration state of the inspection vehicle 100.

[0076] During the medium-speed operation of a maglev train (ranging from 100 km / h to 300 km / h), a single inspection vehicle 100 cannot accurately detect the vibration coupling between the train and the track. Multiple inspection vehicles 100 are required for inspection. In this embodiment, two inspection vehicles 100 conduct inspections on the same track, performing forward and backward inspections of a section of the maglev track 400 within a unit of time. During this process, the two inspection vehicles 100 pass by sequentially at the same speed. Displacement sensors, vibration frequency testers, and acceleration meters are mounted on each inspection vehicle 100. Sensors perform vibration coupling detection on this road section. Two inspection vehicles (100) upload their vibration coupling detection data to inspection station (200). Inspection station (200) compares the data from the two vehicles. When the data from the two vehicles are largely consistent or have small differences (difference rate ≤20%), a corresponding average vibration frequency distribution map is generated to facilitate problem solving. When there is a large difference in the data from the two vehicles, inspection station (200) uploads the data to the central control console (300). The central control console (300) then connects the data with the relevant engineers, allowing for nonlinear H-wave analysis based on the actual situation. ∞ The problem is addressed by establishing a 400-degree coupled dynamic model of the vehicle track through simulation experiments, or by conducting another inspection of the road section as needed.

[0077] In the above process, the data processing of the inspection station 200 includes: collecting the vibration frequency value, displacement sensor value and acceleration sensor value of the inspection vehicle 100 within a unit time, and summarizing the values; organizing the summarized values ​​according to the unit time, and establishing a histogram with the unit time as the horizontal axis and the vertical axis representing the change of vibration frequency value, displacement sensor value and acceleration sensor value within a unit time.

[0078] The high-speed inspection and testing phase mainly tests the degree of vibration frequency coupling between the maglev train and the track 400 under high-speed operation. The inspection vehicle 100 runs at high speed, and the acceleration sensor, displacement sensor and vibration frequency tester on the inspection device all detect the vibration state of the inspection vehicle 100.

[0079] During this phase, the high-speed operation of the inspection vehicle 100 ranges from 300 km / h to 400 km / h, resulting in significant vibration between the magnetic levitation frame and the track 400. This vibration is generated by the interaction between the magnetic levitation train and the track 400, as well as by the effect of the surrounding high-speed airflow.

[0080] During the high-speed phase, the inspection vehicle 100 can inspect the relatively long maglev track 400. Furthermore, high-speed operation maximizes vibration coupling, facilitating the measurement of extreme values. Therefore, in this phase, the speed of the inspection vehicle 100 can be increased to over 400 km / h, which should be the maximum range ensuring the safe operation of the inspection vehicle 100 and surrounding equipment. The collected data, used as measurement data for the inspection vehicle 100, can directly generate corresponding vibration frequency distribution maps, facilitating data processing. Simultaneously, by integrating the data with medium-speed and low-speed vibration frequency distribution maps, the vibration coupling of this section can be easily detected, allowing for appropriate intervention.

[0081] During the aforementioned low-speed, medium-speed, and high-speed inspection phases, displacement sensors on the inspection vehicle 100 are also installed between the vehicle body and the track 400 to facilitate the measurement of offset data values ​​between the vehicle body and the track 400. These offset data values ​​can be processed and integrated through the control terminal, facilitating integration with data from the vibration frequency tester, displacement sensor, and acceleration sensor.

[0082] In the above process, the inspection station 200 needs to process and integrate the data. This processing and integration requires the cooperation of the inspection station 200 and the inspection vehicle 100 to complete. The processing and integration process is mainly carried out in the following ways:

[0083] The inspection station 200 establishes ground-to-ground communication with the inspection vehicle 100, facilitating the transmission of data from the inspection vehicle 100 to the inspection station 200. After the data is transmitted to the inspection station 200, the inspection station 200 can perform node statistics based on the data. This node statistics involves the inspection station 200 calculating the average value of the road segments traveled by an inspection vehicle 100 within a unit of time, thus facilitating data processing.

[0084] During the node statistics process, when there is more than one inspection vehicle 100, multiple inspection vehicles 100 generate multiple node data within a unit of time.

[0085] After generating node data, the inspection station 200 also needs to perform envelope demodulation analysis on the data. The main process is to decompose the data into intrinsic mode functions. At each time moment, the signal has only one frequency component. By performing Hilbert transform on each intrinsic mode function, the instantaneous frequency of each intrinsic mode function can be obtained, which facilitates empirical mode decomposition of the frequency to calculate and generate a vibration frequency distribution map.

[0086] During the processing of multiple inspection vehicles 100, the inspection station 200 can act as a data relay station to facilitate information exchange between adjacent inspection vehicles 100 and avoid collisions between them. At the same time, when there are multiple inspection stations 200, the data can be fused and analyzed through ground-to-ground communication to facilitate data analysis. This data is the vibration coupling data sent by the inspection device, in which the inspection station 200 communicates bidirectionally with the inspection device.

[0087] The above embodiments are only used to illustrate the technical methods of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
