Description

Technical Field

[0001] The present invention relates to the technical field of wheel turning and repairing, and in particular to a method, device, electronic equipment and medium for evaluating a wheelset turning and repairing strategy. Background Art

[0002] Wheel turning is a maintenance method that restores the wheel rim thickness at the expense of the tread diameter. During the advanced maintenance and overhaul of EMUs, wheel turning is required to ensure that the wheel profile meets the maintenance requirements.

[0003] Wheel turning and repairing is an important part of the wheel maintenance of subway vehicles. The wheel tread shape after turning and repairing directly affects the wheel-rail contact relationship and determines the service life of the train wheels. Many people at home and abroad have conducted research on wheel wear analysis, through digital simulation methods of train wheel wear, or on the turning and repairing strategies of train wheels. Some solutions are to establish a high-speed train equipment maintenance decision-making process centered on reliability, and to provide quantitative analysis methods for key issues involved in the maintenance decision-making process, such as equipment importance evaluation, equipment life distribution model establishment, comprehensive state evaluation and prediction, maintenance interval time, and detection interval time determination. There is also a solution to construct a turning and repair optimization model based on SMDP, and use a strategy iteration algorithm to solve the model. The dynamic turning and repair strategy is compared with the fixed turning and repair strategy to verify the effectiveness of the proposed dynamic turning and repair strategy. Another solution is a wheel turning and repair strategy model based on the wheel rim thickness and wheel diameter difference of the entire EMU, and a real-time wheel turning and repair strategy for the wheel diameter difference and wheel rim thickness of the entire EMU is designed, and data verification is given. In summary, implementing the turning and repair scheme using different methods has high research value for ensuring train driving safety and operation and maintenance costs. Summary of the invention

[0063] The main reason for wheel turning is the wear and damage of the wheel tread. Wear indicators such as rim thickness and wheel diameter have a functional relationship with vehicle mileage, and this relationship can be obtained by fitting the statistical data of the wheels during daily maintenance and servicing. Although the surface damage of the wheel tread usually has no obvious statistical regularity, its development process is gradual and can be identified through continuous observation, and turned when the limit requirements are reached. This solution can generate the target wheel diameter and rim thickness for the turning of the whole vehicle wheel in real time according to the statistical function of rim thickness and wheel diameter, the fault conditions observed daily, and the limit requirements after wheel turning.

[0064] This method calculates the wheel according to the deformed profile list output by the wheel lathe, and matches and selects the standard profile template under different rim thicknesses; integrates the development trend of wheel diameter and rim wear rate, builds an estimation model of rim thickness and wear rate development, and estimates the optimal profile under different rim thicknesses, that is, the comprehensive wear amount as the target optimal strategy; integrates the wheel diameter difference calculation, and compensates for the wheelsets with deviations in wheel wear rate. Finally, the optimal wheelset turning and repair plan for the entire carriage is output.

[0079] The turning amount of the wheel to be repaired is determined based on the profile curve of the wheel to be repaired and the standard profile curve; the comprehensive wear amount at each wheel rim thickness is predicted based on the turning amount of the wheel to be repaired and the constructed wheel rim thickness and wear rate model; and the target template wheel rim thickness is determined according to the comprehensive wear amount at each wheel rim thickness, and then the target wheel diameter value of the profile curve after turning is obtained; and the target wheel diameter values ​​of other wheels in the entire vehicle compartment can be predicted according to the target wheel diameter value of the wheel to be repaired and the preset wheel diameter difference compensation model, and the optimal target wheel diameter values ​​of other wheels in the entire vehicle compartment are obtained, and then the turning amount of each wheel is calculated, and a turning plan is specified to reduce maintenance costs.

[0080] In one embodiment, in step S120, when the wear rate of the wheel to be repaired is positive, it means that the rim thickness increases. In order to prevent the rim thickness from increasing to the upper limit of the rim thickness during the repair period, the rim thinning processing model needs to be called to determine the rim thickness recovery amount and the rim wear tread repair correction amount. When the wear rate of the wheel to be repaired is negative, it means that the rim thickness decreases.

[0150] It is the correction amount for wheel rim wear and tread boring.

[0151] S152, determining the value of the corresponding position in the profile curve after the target wheel rim thickness is turned as the target wheel diameter value.

[0152] The value at the point with the horizontal coordinate of 70mm in the profile curve after turning and trimming of the target wheel rim thickness is the target wheel diameter value.

[0153] In one embodiment, step S160 includes:

[0154] S161, obtaining the coaxial wheel diameter difference standard, the left wheel diameter wear rate, and the right wheel diameter wear rate.

[0155] Input the coaxial wheel diameter difference standard dz, the left wheel diameter wear rate v L And the right wheel diameter wear rate v RThe coaxial wheel diameter difference standard is used to define the wheel diameter difference between two wheels on the coaxial axis.

[0156] S162: If the wear rate of the wheel on the side with a smaller wheel diameter is smaller than the wear rate of the wheel on the side with a larger wheel diameter, and the difference between the wheel diameters on the left and right sides gradually decreases with the increase in mileage, no compensation processing is performed.

If the wear rate of the wheel with a smaller wheel diameter on the same axis is greater than the wear rate of the wheel with a larger wheel diameter, and the difference in wheel diameters on the left and right sides gradually decreases and increases with the increase in mileage, then the change in wheel diameter difference during the next turning and repair is predicted according to a preset wheel diameter difference prediction formula.

[0163] Output the maximum downward compensation value dz_v. The wheel diameter value after compensation cannot be smaller than the wheel diameter value of the wheel with a smaller wheel diameter.

[0164] S165: Determine a target wheel diameter value of the coaxial wheel of the wheel to be repaired based on the target wheel diameter value of the wheel to be repaired and the coaxial wheel diameter difference compensation value.

[0165] The target wheel diameter value calculation formula of the coaxial wheel is:

[0166]

[0167] In the formula, is the predicted target wheel diameter value of the coaxial wheel; di is the target wheel diameter value of the wheel to be repaired.

[0168] Similarly, according to the above steps, the wheel diameter difference standard on the same frame can be used to constrain the wheel diameter sizes of the other three wheels on the same frame as the wheel to be repaired, and the recommended target wheel diameter values ​​of the other three wheels can be calculated; and the wheel diameter difference standard on the same compartment can be used to constrain the wheel diameter sizes of the other seven wheels on the same compartment as the wheel to be repaired, and the recommended target wheel diameter values ​​of the other seven wheels can be calculated.
