Method for evaluating use state of high-speed turnout straight steel rail

Abstract

The invention discloses a method for evaluating a use state of a high-speed turnout straight steel rail. The method comprises the following steps: firstly, obtaining turnout steel rail detection data required by state evaluation; then, according to the detection data, establishing a mathematical model for evaluating the use state of the turnout steel rail of the high-speed railway, wherein the mathematical model comprises a state basic scoring part and a disease score deduction part of each detection area; and giving different weights to different measurement items and different detection areas; and evaluating the established mathematical model for evaluating the use state of the high-speed rail turnout through continuously acquired data until the model can intuitively reflect the actual condition of the turnout. According to the method, scientific and effective statistical analysis and other methods are utilized to judge the passing mode of the train, comprehensive evaluation is carried out on the turnout state from multiple angles of wheel sets, frameworks and the whole section of the train body, accurate judgment on the turnout disease condition is achieved, and therefore maintenance of the turnout is scientifically guided, and a support is provided for converting the railway maintenance work from periodic maintenance to state maintenance.

Description

technical field [0001] The invention belongs to the field of track detection, in particular to a method for evaluating the use state of high-speed turnout straight rails. Background technique [0002] The continuous extension of railway operation mileage is changing the way of travel and life of Chinese people, and people have higher and higher requirements for railway speed and operating efficiency. As the connection and conversion equipment between train tracks, the turnout is an important part of the entire track system. Once it fails or is not in good service, it will directly affect the driving efficiency. The maintenance methods and maintenance theory of turnouts are relatively mature at present, and there are relatively clear requirements in the "Maintenance Rules for Ballasted Track Lines of High-speed Railways" and "Rules for Maintenance of Ballastless Track Lines for High-speed Railways". There is currently no systematic approach to detection and assessment method...
