High-speed railway track static comfort analysis adjustment method

Abstract

The invention relates to a high-speed railway track static comfort analysis adjustment method which includes the steps of utilizing a track trolley to measure high-speed railway track parameters to acquire track static measurement data to acquire track static measurement data, after carrying out accurate positioning of the track trolley by using a total station and a control network of foundation piles; drawing the track static measurement data into an oscillogram according to a certain proportion relationship, drawing a variation trend line according to the overall trend of the oscillogram, and carrying out a comfort analysis over the track according to the drawn oscillogram and the variation trend line; calculating adjustment amount required in adjusting the track according to the result of the comfort analysis, and carrying out a site adjustment for the track; carrying out repetition measurement over the track adjusted on site, and carrying out a repeatedly measured data analysis of the adjusted track and local optimization adjustment; if the comfort index of the repeatedly measured data is not in the allowed deviation, getting back to analyze and adjust again, and then generating a track static comfort test report from the analysis and adjustment data.

Description

technical field [0001] The invention relates to detection, analysis and adjustment technologies of railway tracks, in particular to a static smoothness analysis and adjustment method of high-speed railway tracks. Background technique [0002] In order to meet the high safety, high ride comfort and high comfort operating quality requirements of high-speed railways, high-speed railway tracks should have dynamic and static high precision and high ride comfort. Because the static precision of the track directly determines the dynamic precision, the analysis and adjustment of the static ride comfort of the track is one of the key factors to determine the running quality of the high-speed railway. [0003] At present, there are two main methods of static adjustment of the current track in our country. One is the traditional method of measuring the track with track rulers and chords and adjusting the track according to the measurement data; the other is using a track trolley to mea...

Problems solved by technology

[0004] The track adjustment is carried out according to the traditional method of track ruler and chord measurement data. The local (about 20m) track measurement accuracy can reach 0.3-0.5mm, which can realize the precise adjustment of the track, but there are many defects: (1) track measurement automation The degree is low and the workload is huge; (2) The analysis and adjustment of the track elevation, the overall line shape of the plane and the smoothness of the wavelength above 30m cannot be realized; (3) The track adjustment is not systematic

[0006] Therefore, there are many defects: (1) The overall smoothness of the track and the smoothness of the 30-150m wavelength have not been systematically analyzed and adjusted; (2) The smoothness of the two strands of steel rails has not been systematically considered; (3) The standard system for the static smoothness of the track is not perfect; (4) The track accuracy adjusted accordingly cannot fully meet the ride comfort and comfort requirements of 300-350km / h high-speed driving; (5) It is difficult to realize the "minimum The adjustment amount reaches the goal of optimal precision”
