Application of Anti-hunting Motion Dampers on High Speed Trains

The application of anti-hunting motion dampers on high speed trains is discussed. The features of the anti-hunting motion dampers are analyzed. The damping coefficient and unloading force range of the damper are given out. The stiffness at the end of the damper is particularly stressed. Suggestion is also given on the position to install the anti-hunting motion damper, and the effect of the installation height of the damper on the bending vibration of the car-body structure is expounded.
