Abstract

The invention discloses a safety management system for a high-speed train braking component, which comprises a driving data acquisition module, a wear data acquisition module, a time life prediction module and a mileage life prediction module, wherein the driving data acquisition module is used for acquiring driving data of the high-speed train; the wear data acquisition module is used for acquiring wear data w of a braking component on an axle; the time life prediction module is used for acquiring a fitting function T(w) for detection days t and the wear data w through fitting of a least square method, and the detection days t0 when the braking component reaches a wear limit are deduced; and the mileage life prediction module is used for acquiring a fitting function M(w) for a driving mileage m and the wear data w through fitting of the least square method, and the driving mileage m0 when the braking component reaches the wear limit is deduced. Detection data on the braking components corresponding to each high-speed train are unified, service lives of different braking components can be predicted accurately, the maintenance efficiency and the replacement efficiency can be mastered reasonably and effectively, and the driving safety of the high-speed train is improved.

Description

technical field [0001] The invention relates to a safety management system for braking components of high-speed trains, belonging to the field of safe operation of high-speed trains. Background technique [0002] The operating environment of high-speed trains is complex and changeable, and the braking components (brake discs and brake pads) of high-speed trains are the key basic components to ensure driving and braking. There are two ways to install the brake discs of high-speed trains: one is the shaft-mounted brake disc, the brake disc is fixed on the axle, and the corresponding brake pads are also distributed on the axle; the second is the wheel-mounted brake disc. The moving disc and the brake disc are fixedly installed on the wheel, and the brake pads are correspondingly distributed on the wheel. It can be seen from the above two installation positions that the brake disc and brake pad of the high-speed train are installed bare and are the closest to the ground, and ar...
