Influence of Excitation Condition on Evaluating Critical Hunting Speed

In order to verify train bogie running stability, usually, hunting motion tests are carried out on roller rigs. Two types of test are performed: a simple rotation test and an excitation test. It is well known that the critical hunting speed can vary depending on the excitation mode, therefore experiments were conducted to investigate how roller rig excitation waveforms influenced the critical hunting speed. These experiments made it possible to confirm that the occurrence of hunting oscillation depended on the initial lateral amplitude of the free oscillation that was generated by the excitation.
