Embodiment Construction

[0041] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0042] The rail irregularity data processing method of the present invention, such as figure 1 As shown, the specific steps are as follows:

[0043] Step 1: Determine the measurement position of the rail irregularity section according to the on-site rail irregularity information fed back by the railway bureau; at the same time, confirm the irregularity type of the rail irregularity section, such as: wavy wear, rail end irregularity, weld irregularity, etc.

[0044] Step 2: When the train passes through the rail irregular section, measure the vehicle vibration acceleration, noise and vehicle vibration data, and determine the abnormal vibration form of the train caused by the rail irregular section according to these data, so as to determine the required measurement length of the rail irregular section, Such as 3m, 5m or longer range, the specific method is: ...

Abstract

The invention discloses a steel rail irregularity data processing method, which comprises the following stepsf: firstly, determining the position of a steel rail irregularity measurement section, determining a train abnormal vibration form caused by the steel rail irregularity section, and further determining the length of the steel rail irregularity measurement section; measuring the steel rail irregularity section by adopting a 1m straight ruler and an electronic straight ruler to obtain measurement data such as coordinate measurement values of all measurement points; and finally, processingthe measurement data to obtain a coordinate calculation value of the steel rail irregularity section, namely the actual irregularity of the steel rail irregularity section. According to the method, by adopting a related algorithm, existing equipment measurement data are processed, and the surface irregularity of the steel rail within the infinite length range can be calculated.

Description

technical field [0001] The invention belongs to the field of engineering technology, specifically, it is a processing method based on the current rail irregularity measurement data. Background technique [0002] With the rapid development of my country's railways, the problem of track surface irregularities has become increasingly prominent. Irregularity of the rail surface will increase the wheel-rail interaction force, cause abnormal vibration, noise and other problems of the vehicle, and deteriorate the running quality of the vehicle; at the same time, it will damage the line shape and position, and increase the maintenance cost of the railway line. Through investigation, it is found that there are many irregularities in the track surface of high-speed lines in my country, and rail end irregularities appear in some lines, and the peak value of the irregularity is about 0.9mm at most. Under the force of the wheel-rail action, the unevenness of the rail end caused great da...
