Method of correction of railway odometry

摘要

The method involves measuring an angular speed e.g. angular rate of yaw, of a railway vehicle on a section of a railway track during qualification test, and calculating a value of a parameter e.g. stiffness, from the measured single angular speed and an advancement speed of the railway vehicle, where the parameter represents geometry of the track and identified in a reference database. A distance (Pk) varying odometry of the section is calculated to match the calculated geometrical data with the data given by the reference database at the inlet or outlet of the section. An independent claim is also included for a system for evaluating a railway vehicle on a railway track during qualification test.
