Measurement Repeatability of Rail Wheel Loads Caused by Rolling Surface Damages

The repeatability of rail wheel damage measurements is considered in this study. authors investigated the measurement vertical force dependence on wheel-rolling surface nature and suggested ways to reach higher repeatability. To investigate impact repeatability, results measuring forces with different systems were compared first. Another critical issue was estimating deviation field for measured values. box whisker principles used. Different types (shapes) damages rolling stock operating conditions examined by tests. article presents determined authors, how depends speed stock.
