[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

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

[0030] Initial limit of track dynamic irregularity: the initially determined limit of track dynamic irregularity, including daily maintenance limit of track dynamic irregularity, planned maintenance limit of track dynamic irregularity, temporary repair limit of track dynamic irregularity, and speed limit of track dynamic irregularity;

[0031] Daily maintenance limit of track dynamic irregularity: a standard limit set to maintain the track in good condition during daily operation. Track dynamic irregularity should be controlled within this limit as much as possible;

[0032] Track dynamic irregularity planned maintenance limit: When the track dynamic irregularity reaches this limit, systematic maintenance is required according to the pre-established maintenance plan to restore the track to good performance;

[0033] Temporary repair limit for track dynamic irregularity: When the track dynamic irregularity reaches this limit, temporary repair work needs to be carried out immediately;

[0034] Track dynamic irregularity speed limit: When the dynamic irregularity of the track reaches this limit, the train speed must be limited to ensure the safety of train operation and relatively reasonable comfort.

[0035] As mentioned above, there is currently no research on methods for controlling driving safety due to short-wave dynamic irregularities. Therefore, the inventors have conducted research on the relationship between track irregularities and driving performance, determined the short-wave band for controlling driving safety, and based on the measured data of high-speed railway track irregularities, used vehicle-track coupling dynamics simulation, mathematical statistics and other methods to establish a short-wave track dynamic geometric irregularity management method and standard.

[0036] Figure 1 FIG. 1 is an example diagram of a method for controlling short-band dynamic irregularity of a high-speed railway track geometry according to an embodiment of the present invention. Figure 1 As shown, the method includes:

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

[0038] Step 102, statistically analyzing the dynamic irregularity data of the high-speed railway track to obtain the correlation between the dynamic irregularity data of the track in different bands;

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

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

[0041] Step 105: According to the vehicle-track coupled dynamic simulation results and the initial limit of dynamic irregularity, the dynamic irregularity speed limit, the dynamic irregularity planned maintenance limit, and the dynamic irregularity temporary repair limit of the track dynamic short-wave irregularity control band are determined.

[0042] The inventors have found that the periodic irregularities caused by reasons such as railway infrastructure and track structure deformation correspond to the periodic characteristics of wheel-rail force, axle box acceleration and vehicle body acceleration, such as the periodic track irregularities caused by creep of commonly used span simply supported beam bridges and arching of track slabs. The shorter the wavelength of track dynamic irregularities, the greater the peak values ​​of axle box acceleration and wheel-rail force spectrum, and the wheel-rail force and axle box acceleration responses have the largest amplitude in the short-wave section below 10m.

[0043] In an embodiment, feature analysis is performed on the disease data and dynamic irregularity data of the high-speed railway track to obtain feature analysis results, and the track dynamic short-wave irregularity control band is determined according to the feature analysis results, which may include: feature analysis is performed on the frequency spectrum of the disease data and dynamic irregularity data of the high-speed railway track to obtain feature analysis results, and according to the feature analysis results, it is determined that the [1.5m, 10m] band is the track dynamic short-wave irregularity control band.

[0044] For example, by conducting characteristic analysis on track slab defects of ballastless track, measured track height at the end of a long-span bridge beam, and dynamic irregularity of the track; Figure 2 FIG. 1 is a spectrum diagram of track irregularity of a 32 m simply supported beam bridge on a ballastless track in an embodiment of the present invention; Figure 2As shown in the figure, the track irregularity amplitude is most obvious in the [1.5m, 10m] band; according to the analysis results, the dynamic track irregularity in the [1.5m, 10m] band is clearly controlled.

[0045] In an embodiment, statistical analysis is performed on the dynamic irregularity data of the high-speed railway track to obtain the correlation between the dynamic irregularity data of the track in different bands, which may include: statistical analysis is performed on the dynamic irregularity data of the high-speed railway track to obtain the correlation between the dynamic irregularity data of the track in the [1.5m, 10m] and [1.5m, 42m] bands at different speed levels.

[0046] For example, based on the dynamic irregularity data of ballastless and ballasted tracks of high-speed railways, the linear relationship between the height and amplitude of the [1.5m, 10m] and [1.5m, 42m] bands and the track irregularity at different speed levels is statistically analyzed, and the correlation equation is given;

[0047] Roughness amplitude:

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

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

[0050] Track irregularity amplitude:

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

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

[0053] Where y is the roughness amplitude of the [1.5m, 10m] band, in mm; x is the roughness amplitude of the [1.5m, 42m] band, in mm. Formulas (1) and (3) are applicable to the speed level of [200km / h, 250km / h]; Formulas (2) and (4) are applicable to the speed level of (250km / h, 350km / h].

[0054] In an embodiment, determining the initial limit value of dynamic irregularity of the track dynamic shortwave irregularity control band according to the correlation between track dynamic irregularity data of different bands and the allowable deviation management value of track dynamic irregularity data of different bands may include: determining the initial limit value of dynamic irregularity of the [1.5m, 10m] band track dynamic shortwave irregularity control band according to the correlation between track dynamic irregularity data of [1.5m, 10m] bands and [1.5m, 42m] bands at different speed levels and the allowable deviation management value of track dynamic irregularity data of [1.5m, 42m] bands.

[0055] For example, based on the linear relationship between the track dynamic irregularity data of the [1.5m, 42m] band and the [1.5m, 10m] band, referring to the allowable deviation management values ​​of the high and low and track-direction dynamic irregularities of the [1.5m, 42m] band, the initial limit values ​​of the hierarchical management of track dynamic irregularity of the [1.5m, 10m] band are preliminarily given; Table 1 is the initial limit values ​​of the hierarchical management of track dynamic irregularity of the [1.5m, 10m] band in an embodiment of the present invention; as shown in Table 1:

[0056] Table 1 Initial limits for graded management of track dynamic irregularities in the [1.5m, 10m] band

[0057]

[0058] In the embodiment, lines with different speed levels are selected, and the dynamic roughness amplitude of the track dynamic short-wave roughness control band is statistically analyzed to obtain the peak value and cumulative distribution value of the dynamic roughness amplitude of the track dynamic short-wave roughness control band; based on the peak value and cumulative distribution value and the initial limit value of the dynamic roughness, the daily maintenance limit value of the dynamic roughness of the track dynamic short-wave roughness control band is determined.

[0059] Figure 3 FIG. 1 is a specific example diagram of determining the daily maintenance limit of the track dynamic short-wave irregularity control band in an embodiment of the present invention; Figure 3 As shown, lines with different speed levels are selected, and the dynamic roughness amplitude curve of the track dynamic short-wave roughness control band is obtained by high-pass filtering. The dynamic roughness amplitude curve is statistically analyzed to obtain the maximum value and the cumulative distribution value of the preset confidence interval of the dynamic roughness amplitude of the track dynamic short-wave roughness control band; according to the maximum value and the cumulative distribution value of the preset confidence interval, the initial limit of dynamic roughness is used to determine the daily maintenance limit of the dynamic roughness of the track dynamic short-wave roughness control band.

[0060] For example, multiple high-speed railway lines with operating speeds of 250km / h, 350km / h and 400km / h were selected, and the amplitude curves of the height and dynamic track irregularity in the [1.5m, 10m] band were obtained through high-pass filtering. The maximum values ​​and positions of the height and dynamic track irregularity in the [1.5m, 10m] band were counted, and the cumulative distribution statistics of the height and track irregularity of the entire line were performed. Figure 4 FIG. 4 is a specific example diagram of cumulative distribution statistics of the [1.5m, 10m] and [1.5m, 42m] bands in an embodiment of the present invention. Figure 4 As shown, the corresponding 95% cumulative distribution value is given, and the daily maintenance limit of dynamic irregularity level I in the track dynamic shortwave irregularity control band is determined based on the maximum value and the 95% cumulative distribution value.

[0061] In an embodiment, determining the dynamic irregularity speed limit value, the dynamic irregularity planned maintenance limit value, and the dynamic irregularity temporary repair limit value of a track dynamic shortwave irregularity control band according to the vehicle and track coupled dynamic simulation results and the initial limit value of dynamic irregularity may include: determining the dynamic irregularity speed limit value of a track dynamic shortwave irregularity control band according to the vehicle and track coupled dynamic simulation results and the initial limit value of track dynamic irregularity in the [1.5m, 10m] band in combination with a predetermined safety index, determining the dynamic irregularity planned maintenance limit value, and the dynamic irregularity temporary repair limit value of a track dynamic irregularity control band.

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

[0063] Table 2 [1.5m, 10m] band track dynamic quality allowable deviation management values

[0064]

[0065]

[0066] In an embodiment, after determining the dynamic irregularity speed limit value, dynamic irregularity planned maintenance limit value, and dynamic irregularity temporary repair limit value of the track dynamic shortwave irregularity control band according to the vehicle and track coupled dynamic simulation results and the dynamic irregularity initial limit value, it may also include: verifying the applicability of the dynamic irregularity speed limit value, dynamic irregularity daily maintenance limit value, dynamic irregularity planned maintenance limit value, and dynamic irregularity temporary repair limit value of the track dynamic shortwave irregularity control band according to the actual measured track dynamic irregularity data of high-speed railways at multiple different speed levels.
