Embodiment Construction

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0036] The inventors of the embodiments of the present invention found that the detection method for measuring the wheel-rail force in the prior art can detect the vertical force and lateral force on the wheel, which is used to analyze the safety of the wheel during driving, and the wheel is running on the track The impact force on the wheel is also the impact force on the track. By analyzing the different impact forces of the wheels on the track, the condition of t...

Abstract

The invention relates to the field of railway vehicle wheel track measurement and track quality detection, in particular to a track detection method and device, aiming to solve the problem that only geometric modes exist in the track detection but no power action parameters exist in the track detection in the prior art, wherein the method comprises the steps of: detecting and obtaining detection data from vertical force and transverse force (wheel track force) which mutually act between wheel tracks; calculating the wheel track force detection data, distinguishing different frequency bands toobtain wheel track force effective data; and analyzing and judging the track quality condition according to the wheel track force effective data. The embodiment of the invention has the advantages ofdetecting the track quality condition by using the detection result of the wheel track force, effectively reflecting the state of the tracks more accurately and completely, and more completely ensuring the safety and the reliability of a railway vehicle and a track line by combining with the traditional track detection technology.

Description

technical field [0001] The invention relates to the field of railway vehicle wheel-rail force measurement and track quality inspection, in particular to a track detection method and device. Background technique [0002] With the rapid development of heavy-duty and high-speed railways, railway safety issues are becoming more and more important, and track safety detection is particularly important. [0003] At present, the domestic and international railway track condition detection mainly adopts geometric detection method, which usually uses image, laser, gyroscope, displacement meter, acceleration sensor and other detection equipment to measure whether the geometric shape of the track meets the standard to achieve the purpose of detecting the track condition. However, the above method cannot detect the actual dynamic parameters between the wheel and rail, and cannot be directly used to evaluate the state of the track structure and its impact on the safety and stability of tr...
