Article in ETR "Design of wheelset-shafts taking into account the maximum, dynamic torsional moment" (in GERMAN only).
The design of wheelset shafts is associated with high uncertainties due to the unknown maximum dynamic torsional moment. If too high dynamic torsional moments are determined in the homologation measurements there is a risk that the strength verification for the installed wheelset shaft cannot be passed successfully. Subsequent design modifications, if possible at all, are expensive and the approval process is considerably prolonged. It is therefore worthwhile to pay the necessary attention to this topic already in the design phase. Thereby PROSE can support with experience and expertise.
