This report describes the development of a displacement-dependent rubber bush to prevent carbody vibration of railway vehicles induced by rotation of wheelset(s) with small mass imbalance. The displacement-dependent property is realized by introducing a small gap between the rubber and the inner fixture, and transmission of the excitation force is isolated by the gap. Excitation tests using a full-scale test vehicle to verify the vibration isolation performance and running stability testing with a bogie are carried out in the rolling stock testing plant at RTRI. Then a series of running tests on a commercial line is conducted and the effectiveness of the displacement-dependent rubber bush has been confirmed.
