What is PD CEN/TR 17792 – W heel-rail contact geometry parameters about?
PD CEN/TR 17792 is a standard that covers technical report and information about wheel-rail contact geometry parameters, ensuring stability, performance and efficiency in railway applications. PD CEN/TR 17792 provides background information regarding the changes from EN 15302:2008+A1:2010 to the revised version dated 2021, including the reasons for decisions and additional explanation and guidance that is not appropriate in PD CEN/TR 17792 . The range of equivalent conicity results obtained with different software tools is described in PD CEN/TR 17792 . In PD CEN/TR 17792 , guidance is given on fields of application of the wheel-rail contact parameters, on the selection of appropriate reference profiles (choice of reference rail profile and rail inclination for assessing wheel profiles and vice versa) and on handling special cases. As some references in EN 14363 to wheel-rail contact test conditions have caused difficulties in understanding, clarifications issued by ERA are mentioned. In PD CEN/TR 17792 , the interpretation of equivalent conicity results, using tools such a...
