    Abstract
  • The chatter phenomenon of some locomotives and vehicles with lightning carbodies and bogies was analysed, which is very harmful to the carbodies, the ride comfort of passengers and environment.In order to decrease the level of the chatter in the condition of braking, the chatter mechanism was studied, the inflnence factors of the chatter were analysed, the dynamics relation of chatter and braking was put forward.The numerical simulation results show that the chatter is generated by the self-excited vibration of vehicle system at low speed, the chatter is related with the structure of vehicle bogie, carbody and suspension system, the chatter can be avoided by adjusting the parameters of bogie system and changing bogie frame design.
