Abstract
A railway vehicle wheel experiences the problem of hunting motion above a critical speed, which is caused by the contact force between the wheels and rails. The resonance is one of flutter-type self-excited oscillations and the growth of the response amplitude can lead to the derailment of railway vehicles. In our previous studies, a stabilization control method using a gyroscopic damper is proposed, which does not make the yawing motion mechanically stiffer. In this paper, an improved method considering constant curve was proposed.
