Problems solved by technology

The wheel diameter difference affects the safety and stability of the vehicle, and even affects the driving safety
At present, the detection and evaluation of the wheel diameter difference is based on the wheel diameter at the nominal rolling circle of the left and right wheel treads. This method only relies on the wear situation at a point of the nominal rolling circle to evaluate. However, the wheel wear is distributed on the left and right sides of the nominal rolling circle of the tread. Within the range, it is difficult to evaluate the wheel diameter difference only by local wear conditions to reflect the influence of the overall wear of the tread, and there is a problem of inaccurate test results

Abstract

The invention relates to a wheel set wheel diameter difference detection method and device, computer equipment, a storage medium and a computer program product. The method comprises the following steps: measuring a wheel tread of a wheel set, and obtaining tread curve data of the wheel set; the tread curve data comprises left wheel tread curve data and right wheel tread curve data; determining tread abrasion distribution data based on the tread curve data; the tread abrasion distribution data comprises left wheel tread abrasion distribution data and right wheel tread abrasion distribution data; processing the tread abrasion distribution data to obtain wheel diameter difference distribution data of the tread, and outputting a wheel diameter difference detection result based on a weight coefficient of the wheel diameter difference distribution data; the wheel diameter difference distribution data comprises wheel diameter difference data at the contact position of each rolling circle. By adopting the method, the wheel diameter difference can be detected according to the global abrasion condition of the tread.

Description

technical field [0001] The present application relates to the technical field of railway transportation, in particular to a method and device for detecting wheel diameter difference of a wheel set. Background technique [0002] After the implementation of the sixth speed increase of the railway, higher requirements have been put forward for the vehicle transportation department. As the operating speed of freight trains is getting higher and higher, the quality of railway freight car maintenance is facing a more severe test. At present, the proportion of common faults in the use of railway freight train wheels is still high, which will inevitably restrict the speed-up of railway freight trains and affect the safety of driving. [0003] The diameter difference of the wheel set refers to the phenomenon that the diameter of the nominal rolling circle of the wheel is inconsistent due to the inconsistent wear degree of the left and right wheels of the same wheel set during the se...
