[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0029] First, the technical terms in the embodiments of the present application are introduced:

[0030] Track dynamic irregularity initial limit value: a preliminarily determined track dynamic irregularity limit value, including a track dynamic irregularity daily maintenance limit value, a track dynamic irregularity planned maintenance limit value, a track dynamic irregularity temporary repair limit value, and a track dynamic irregularity speed limit value;

[0031] Track dynamic irregularity daily maintenance limit value: a standard limit value set to maintain the track in a good state in daily operation, and the track dynamic irregularity should be controlled within this limit value as much as possible;

[0032] Track dynamic irregularity planned maintenance limit value: when the track dynamic irregularity reaches this limit value, systematic maintenance needs to be performed according to a pre-prepared maintenance plan to restore the good performance of the track;

[0033] Track dynamic irregularity temporary repair limit value: when the track dynamic irregularity reaches this limit value, temporary repair work needs to be performed immediately;

[0034] Track dynamic irregularity speed limit value: when the track dynamic irregularity reaches this limit value, the train running speed needs to be limited to ensure the safety and relative comfort of train operation.

[0035] As described above, since the method for controlling train safety in terms of dynamic irregularity short-wave control is still blank at present, the inventors have carried out research on the relationship between track irregularity and train performance, determined the short-wave control for controlling train safety, and based on the measured data of high-speed railway track irregularity, established a short-wave track dynamic geometry irregularity management method and standard by using vehicle-track coupling dynamics simulation and mathematical statistics.

[0036] Figure 1 Figure 1 is a structural diagram of a high-speed railway track geometry short-wave dynamic irregularity control device according to an embodiment of the present application. Figure 1 As shown in Figure 1, the method comprises the following steps.

[0037] Step 101, performing feature analysis on the disease data and dynamic irregularity data of the high-speed railway track to obtain a feature analysis result, and determining a track dynamic short-wave irregularity control wave band according to the feature analysis result;

[0038] Step 102, performing statistical analysis on the dynamic irregularity data of the high-speed railway track to obtain a correlation between the track dynamic irregularity data of different wave bands;

[0039] Step 103, determining an initial limit value of the dynamic irregularity of the track dynamic short-wave irregularity control wave band according to the correlation between the track dynamic irregularity data of different wave bands and the allowable deviation management value of the track dynamic irregularity data of different wave bands;

[0040] Step 104, selecting lines of different speed levels to perform statistical analysis on the dynamic irregularity amplitude of the track dynamic short-wave irregularity control wave band to obtain a peak value and a cumulative distribution value of the dynamic irregularity amplitude of the track dynamic short-wave irregularity control wave band; and determining a daily maintenance limit value of the dynamic irregularity of the track dynamic short-wave irregularity control wave band according to the peak value and the cumulative distribution value, the initial limit value of the dynamic irregularity, and the dynamic irregularity of the track dynamic short-wave irregularity control wave band.

[0041] Step 105, determining a speed limit value, a planned maintenance limit value, and a temporary repair limit value of the dynamic irregularity of the track dynamic short-wave irregularity control wave band according to the vehicle and track coupling dynamic simulation results and the initial limit value of the dynamic irregularity.

[0042] The inventor found that the periodic irregularity caused by the deformation of railway infrastructure and track structure has a corresponding relationship with the periodic characteristics of wheel-rail force, axle box acceleration, and car body acceleration, such as the periodic track irregularity caused by the creep of a commonly used simply supported beam bridge and the upward arch of a track slab. The shorter the wavelength of the track dynamic irregularity, the greater the peak value of the axle box acceleration and the wheel-rail force spectrum, and the wheel-rail force and axle box acceleration response have the maximum amplitude in the short wave segment below 10m.

[0043] In the embodiment, the feature analysis on the disease data and dynamic irregularity data of the high-speed railway track to obtain a feature analysis result, and the determination of the track dynamic short-wave irregularity control wave band according to the feature analysis result can include: performing feature analysis on the frequency spectrum of the disease data and dynamic irregularity data of the high-speed railway track to obtain a feature analysis result, and determining the [1.5m, 10m] wave band as the track dynamic short-wave irregularity control wave band according to the feature analysis result.

[0044] For example, by performing feature analysis on the track slab disease of the ballastless track, the measured track height and alignment dynamic irregularity of the beam end of the long-span bridge; Figure 2 The track irregularity frequency spectrum diagram of the 32m simply supported beam bridge of the ballastless track in the embodiment of the application is as follows: Figure 2As shown, the track irregularity amplitude in the [1.5m, 10m] band is the most obvious; according to the analysis result, the track dynamic irregularity in the [1.5m, 10m] band is controlled.

[0045] In the embodiment, the dynamic irregularity data of the high-speed railway track is statistically analyzed to obtain the correlation between the dynamic irregularity data of different wave bands, which can include: statistically analyzing the dynamic irregularity data of the high-speed railway track to obtain the correlation between the [1.5m, 10m] and [1.5m, 42m] wave band dynamic irregularity data under different speed levels.

[0046] For example, based on the dynamic irregularity data of high-speed railway ballastless and ballasted tracks, the linear relationship between the [1.5m, 10m] and [1.5m, 42m] wave band high-low and alignment irregularity amplitude under different speed levels is statistically analyzed, and the correlation formula is given;

[0047] High-low irregularity amplitude:

[0048] y = 0.447x + 0.597 (1)

[0049] y = 0.526x + 0.308 (2)

[0050] Alignment irregularity amplitude:

[0051] y = 0.523x + 0.520 (3)

[0052] y = 0.507x + 0.529 (4)

[0053] Where y is the [1.5m, 10m] wave band irregularity amplitude, unit mm; x is the [1.5m, 42m] wave band irregularity amplitude, unit mm. Formula (1), (3) is applicable to speed level [200km / h, 250km / h]; Formula (2), (4) is applicable to speed level (250km / h, 350km / h].

[0054] In the embodiment, according to the correlation between the dynamic irregularity data of different wave bands and the allowable deviation management value of the dynamic irregularity data of different wave bands, the initial limit value of the dynamic irregularity of the track dynamic short wave irregularity control wave band is determined, which can include: according to the correlation between the [1.5m, 10m] and [1.5m, 42m] wave band track dynamic irregularity data under different speed levels, and the allowable deviation management value of the [1.5m, 42m] wave band track dynamic irregularity data, the initial limit value of the dynamic irregularity of the [1.5m, 10m] wave band track dynamic short wave irregularity control wave band is determined.

[0055] For example, based on the linear relationship between the [1.5m, 42m] wave band and the [1.5m, 10m] wave band track dynamic irregularity data, referring to the allowable deviation management value of the [1.5m, 42m] wave band high-low, track dynamic irregularity, the initial limit value of the [1.5m, 10m] wave band track dynamic irregularity grading management is preliminarily given; Table 1 is the initial limit value of the [1.5m, 10m] wave band track dynamic irregularity grading management in the embodiment of the present application; as shown in Table 1:

[0056] Table 1 Initial limit value of [1.5m, 10m] wave band track dynamic irregularity grading management

[0057]

[0058] In the embodiment, the dynamic irregularity amplitude of the track dynamic short wave irregularity control wave band is statistically analyzed by selecting lines of different speed grades, and the peak value and cumulative distribution value of the dynamic irregularity amplitude of the track dynamic short wave irregularity control wave band are obtained; according to the peak value and cumulative distribution value, the dynamic irregularity initial limit value, the dynamic irregularity daily maintenance limit value of the track dynamic short wave irregularity control wave band is determined.

[0059] Figure 3 A specific example of determining the daily maintenance limit value of the track dynamic short wave irregularity control wave band in the embodiment of the present application is shown in FIG. 1; Figure 3 As shown in FIG. 1, the dynamic irregularity amplitude curve of the track dynamic short wave irregularity control wave band is obtained by high-pass filtering by selecting lines of different speed grades, and the maximum value and cumulative distribution value of the pre-set confidence interval of the dynamic irregularity amplitude curve are obtained by statistically analyzing the dynamic irregularity amplitude curve; according to the maximum value and cumulative distribution value of the pre-set confidence interval, the dynamic irregularity initial limit value, the dynamic irregularity daily maintenance limit value of the track dynamic short wave irregularity control wave band is determined.

[0060] For example, a plurality of high-speed railway lines with operating speeds of 250km / h, 350km / h and 400km / h are selected, and the [1.5m, 10m] wave band high-low, track dynamic irregularity amplitude curve is obtained by high-pass filtering, the maximum value and position of the [1.5m, 10m] wave band high-low, track dynamic irregularity amplitude are counted, and the cumulative distribution of the high-low, track irregularity is counted, Figure 4 A specific example of counting the cumulative distribution of [1.5m, 10m] and [1.5m, 42m] wave bands in the embodiment of the present application is shown in FIG. 2; Figure 4 As shown in FIG. 2, the cumulative distribution value corresponding to 95% is given, and the dynamic irregularity I level daily maintenance limit value of the track dynamic short wave irregularity control wave band is determined according to the maximum value and the cumulative distribution value of 95%.

[0061] In the embodiment, the dynamic irregularity speed limit value, the dynamic irregularity planned maintenance limit value, and the dynamic irregularity temporary repair limit value of the track dynamic short-wave irregularity control band are determined according to the vehicle-track coupling dynamic simulation result and the initial limit value of the dynamic irregularity, which can include: determining the dynamic irregularity speed limit value, the dynamic irregularity planned maintenance limit value, and the dynamic irregularity temporary repair limit value of the track dynamic short-wave irregularity control band according to the vehicle-track coupling dynamic simulation result and the initial limit value of the track dynamic irregularity in the [1.5m, 10m] band, in combination with the predetermined safety index.

[0062] For example, the IV level speed limit value of the track dynamic irregularity in the [1.5m, 10m] band is determined according to the driving safety index and the control standard through the vehicle-track coupling dynamic simulation, and then the II level planned maintenance of the dynamic irregularity and the III temporary repair management value of the dynamic irregularity are determined. Table 2 is the track dynamic quality allowable deviation management value in the [1.5m, 10m] band in the embodiment of the present application, which includes the dynamic irregularity daily maintenance limit value, the dynamic irregularity speed limit value, the dynamic irregularity planned maintenance limit value, and the dynamic irregularity temporary repair limit value of the track dynamic short-wave irregularity control band, as shown in Table 2.

[0064]

[0065]

[0066] In the embodiment, after the dynamic irregularity speed limit value, the dynamic irregularity planned maintenance limit value, and the dynamic irregularity temporary repair limit value of the track dynamic short-wave irregularity control band are determined according to the vehicle-track coupling dynamic simulation result and the initial limit value of the dynamic irregularity, the applicability verification of the dynamic irregularity speed limit value, the dynamic irregularity daily maintenance limit value, the dynamic irregularity planned maintenance limit value, and the dynamic irregularity temporary repair limit value of the track dynamic short-wave irregularity control band can be further included according to the measured track dynamic irregularity data of the high-speed railway at multiple speed levels.
