Abstract:
A diagnostic method and apparatus for a shaft breakage fault of a railway vehicle. The diagnostic method for a shaft breakage fault of a railway vehicle can perform shaft breakage fault diagnosis on a plurality of axles of the railway vehicle. The diagnostic method comprises the following steps: determining an operating condition of the railway vehicle; in response to the fact that the railway vehicle is in a traction condition, taking an axle (241) in the plurality of axles (241-246) as an axle to be measured to determine a first shaft breakage condition, the first shaft breakage condition comprising that the actual traction of other axles than said axle is greater than a first traction threshold, the actual traction of said axle is continuously less than a second traction threshold, and the axle speed continuously greater than the railway vehicle speed reaches a first time threshold; and if the first shaft breakage condition is satisfied, determining that said axle is suspected to be broken. The diagnostic method for a shaft breakage fault can rapidly and accurately report a fault, so as to ensure the safe operation of the train. In addition, also provided are an apparatus for a shaft breakage fault of a railway vehicle and a computer readable medium.
