Description

Technical Field

[0001] The present invention relates to the technical field of dynamic car wheel balancing, and particularly to a method, a system, a device, a medium and a product for suppressing the eccentricity of dynamic car wheels. Background Art

[0002] In the 1870s, the Canadian Henry Martinson first proposed the balancing technology to measure and correct the imbalance of rotating machinery. With the development of mechatronics technology and the popularization of rotor self-balancing technology, scholars in various countries have developed various types of automatic balance controllers, including motor balancers, hydraulic balancers and electromagnetic balancers, to perform dynamic balance verification on rotating objects. The electromagnetic automatic balance device has a relatively simple structure and working principle, mainly composed of electromagnetic coils, magnets and control circuits, and can provide a relatively high response speed, accuracy and sensitivity. At the same time, it has strong adaptability and versatility, and can be applied to various rotating mechanical equipment and systems to self-heal and regulate their unbalance.

[0003] With the rapid development of the railway transportation industry, as a key component of the transportation system, the performance of wheels directly affects the operation efficiency and safety of trains. However, while the speed of dynamic cars is constantly increasing, the wear problem caused by wheel eccentricity has become increasingly serious. Uneven mass distribution during the manufacturing process of wheels, imperfect balance treatment, or insufficient tightening torque during the installation process may all lead to the eccentricity problem of wheels. Eccentric wheels will generate vibrations and noises during high-speed driving, affecting the smoothness and comfort of driving. In severe cases, it will cause uneven contact between the wheels and the track, trigger resonance problems, further exacerbate wheel wear, and even pose safety hazards to the train and the surrounding environment.

[0004] At present, the domestic research on automatic balance devices mainly focuses on equipment fields such as steam turbines, lathes, grinding wheels, and aviation generators. There is relatively little research on the automatic balance technology for high-speed train wheels, and there are relatively large gaps in related technologies. Therefore, developing an effective technical solution to suppress the eccentricity of dynamic car wheels has important practical significance for improving the comprehensive performance of dynamic car operation.

[0031] The realization of the purpose of the present application, functional features and advantages will be further described in conjunction with the embodiments with reference to the accompanying drawings. Detailed implementation manners

[0032] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application. On the contrary, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0033] Regarding the foregoing and other technical contents, features and effects of the present invention, in the following detailed description of the embodiments in conjunction with the attached Figures 1-4 It will be clearly presented in the detailed description of the embodiments. The structural contents mentioned in the following embodiments are all referenced to the accompanying drawings of the specification.

[0034] The following will describe the exemplary embodiments of the present invention with reference to the accompanying drawings.

[0035] Referring to Figure 1 , Figure 1 It is a schematic flow chart of a method for suppressing the eccentricity of the wheels of a bullet train shown in the present application. As Figure 1 shown, the method may include S1 - S5. This method can be applied to a system for suppressing the eccentricity of the wheels of a bullet train.

[0036] S1: Real - time monitor the initial parameters of the wheels of the bullet train. The initial parameters include the position of the counterweight disc, the speed of the bullet train, and the vibration signal data, and store the initial parameters in the real - time state condition database.

[0037] The acquisition of initial parameters is achieved by installing sensors on the EMU wheels. The sensors include, but are not limited to, acceleration sensors, angular velocity sensors, displacement sensors, force sensors, and temperature sensors. These sensors collect various parameters during the operation of the wheels in real time. For example, the acceleration sensor collects the wheel vibration acceleration data, the angular velocity sensor obtains the angular velocity of the wheel rotation, and the displacement sensor monitors the change in the radial displacement of the wheel, etc.

[0038] Furthermore, after the sensors collect various parameters during the operation of the wheels, a mature data acquisition system (DAQ) is used to collect these raw data, which are amplified through a signal conditioning circuit, the high-frequency noise is removed using a low-pass filter, and then the analog signal is converted into a digital signal by an analog-to-digital converter (ADC) and stored in the real-time state condition database. The real-time state condition database is used to efficiently store and manage a large number of real-time data streams collected from the DAQ. This database adopts a time series data model, which can not only quickly capture and update data, but also save storage space through data compression technology, while ensuring the accuracy and integrity of the data.

[0039] S2: Input the collected vibration signal into the signal processing system for signal analysis. The time-domain signal is converted into a frequency-domain signal through Fourier transform to obtain the spectral information of the vibration signal, and the main vibration modes of the EMU wheels are extracted.

[0040] Among them, the signal processing system includes a digital signal processor (DSP). Digital filtering is implemented on the DSP to remove noise or extract signals within a specific frequency range. Specifically, digital filtering is implemented on the DSP to remove the noise interference in the signal and extract the useful signal components. The time-domain vibration signal is converted into a frequency-domain signal using Fourier transform, according to the formula:

[0041]

[0042] where X[k] is the k-th component of the frequency-domain signal; x[n] is the n-th sampling point of the time-domain signal; and N is the number of samples.

[0043] Furthermore, calculate the power spectral density of the signal to evaluate the energy distribution at different frequencies. The formula is:

[0044]

[0045] where P x (f) is the power spectral density of the signal (W / Hz); X(f) is the amplitude of the frequency-domain signal.

[0046] Further, wavelet transform is used for time-frequency analysis to identify the variation of vibration signals over time, which helps to locate the eccentricity position and degree. According to the formula:

[0047]

[0048] where a is the scale parameter (controlling the width of the wavelet, corresponding to the reciprocal of the frequency), b is the translation parameter (controlling the time position of the wavelet), is the complex conjugate of the mother wavelet function.

[0049] Further, key characteristic parameters such as vibration amplitude, frequency components, and phase information are extracted from the spectrum and time-frequency analysis results.

[0050] According to the characteristic parameters of the main vibration modes, the residual static unbalance of the wheel is calculated. The calculation of the residual static unbalance of the EMU wheel satisfies the following formula:

[0051] |U| = mr

[0052] where m is the eccentric mass of the wheel set, and r is the distance between the eccentric mass of the wheel set and the rotation center.

[0053] Meanwhile, the DSP system monitors the abnormal conditions in the signal in real time, such as suddenly increased vibration or couple. Once an abnormality is detected, the safety mechanism is triggered in time to take preventive protection measures to avoid potential damage.

[0054] S3: According to the characteristic parameters of the main vibration modes, calculate the residual static unbalance of the wheel, and verify whether the residual static unbalance exceeds the preset range; if the residual static unbalance exceeds the preset range, then execute step S4.

[0055] In a specific embodiment, referring to the acceptance standards for railway wheel sets formulated by multiple countries and organizations: when the vehicle speed is greater than 200 km / h, the residual static unbalance of the wheel should be less than or equal to 50 g·m.

[0056] Therefore, in this embodiment, if the residual static unbalance is greater than 50 g·m, it is determined to start the electromagnetic automatic balance control device; if it is less than or equal to 50 g·m, the real-time monitoring of the wheel operation parameters is continued.

[0057] S4: According to the residual static unbalance at the current moment, calculate the centrifugal force and unbalanced couple generated by eccentricity of the left and right wheels, and determine the action direction of the counterweight disc.

[0058] As Figure 2 shown, when the wheel set rotates at high speed, the residual static unbalances of the left and right wheels will generate two alternating centrifugal forces in opposite directions. According to the residual static unbalance at the current moment, the centrifugal forces caused by the residual unbalances of the left and right wheels are calculated by the following formula:

[0059] F W1 = F W2 = |U|ω 2

[0060] where F W1 and F W2 are the centrifugal forces caused by the residual static unbalance of the left and right wheels of the EMU respectively, |U| is the residual static unbalance, and ω is the angular velocity of the wheel rotation.

[0061] The angular velocity ω is calculated according to the following formula:

[0062]

[0063] where v is the train speed and R is the radius of the wheel of the EMU.

[0064] When F W1 > F W2 then F W is the alternating centrifugal force on the wheel set:

[0065] F W = F W1 - F W2

[0066] The centrifugal forces caused by the residual static unbalances on the left and right of the wheel will generate a couple moment, thus causing the couple unbalance of the EMU wheel set. This couple moment can be calculated according to the following formula:

[0067] M = F W L

[0068] where M is the couple moment caused by the residual static unbalance of the wheel set and L is the distance between the center points of the wheel and the axle.

[0069] S5: Control the electromagnetic automatic balancing device to adjust the electromagnetic field. By changing the current and the magnetic field direction, drive the electromagnetic balancing head to rotate to generate a corresponding moment to balance the couple moment caused by the wheel eccentricity.

[0070] According to the calculated couple moment M and the vibration analysis results, determine the action direction and position of the counterweight disk. The electromagnetic automatic balancing device controls the electromagnetic field, adjusts the current and the magnetic field direction, drives the electromagnetic automatic balancing device to rotate, so that the counterweight disk reaches the target balance position to generate a corresponding moment to balance the couple moment caused by the wheel eccentricity, solves the couple unbalance problem of the wheel set, and realizes dynamic balance.

[0071] During the balancing process, a closed-loop control strategy is implemented to continuously monitor the wheel vibration signal and power spectral density. The counterweight is dynamically adjusted according to the calculation results until the predetermined balance standard is reached. At the same time, key data during the processing is recorded, such as the current and magnetic field parameters for each adjustment, the change in the residual static unbalance, etc. These data are analyzed to optimize the balancing algorithm and improve the overall performance of the system.

[0072] Based on the same inventive concept, an embodiment of the present application also provides a system for suppressing the eccentricity of a bullet train wheel for implementing the method for suppressing the eccentricity of a bullet train wheel involved above.
