Rail wheel measurement

摘要

A method of determining a remaining service life for a rail wheel ( 18 ) of a railway vehicle using an electronic rail wheel ( 18 ) wear gauge ( 10 ) mountable on the rail wheel for measuring at least one rail wheel dimension. The method includes measuring a rail wheel dimension and processing the measured wheel dimension relative to an allowable wear dimension. The method also includes accessing a historical wheel wear rate database ( 44 ) relating to the rail wheel and predicting a remaining service life of the wheel based on the historical wheel wear rate data and the processed wheel dimension.
