Keywords: limit cycle, bifurcation, vibration, Andronov-Hopf, bogie, hunting oscillation.

Summary

This paper includes a study of the effect of hunting oscillations in the dynamic behaviour of a bogie. These oscillations are associated with Andronov-Hopf bifurcation that leads to the appearance of limit cycle oscillations. The soft and hard types of instability related to the supercritical and subcritical Andronov-Hopf bifurcation are studied. A dynamic model of a bogie along with the rolling rail-wheel contact interaction and single wheel set is considered. The proposed numerical algorithm for calculating a critical speed of the bogie is based on the first Lyapunov number. The numerical algorithm is validated by analytical results, derived for a simple model.
