Abstract:The wheelset is normally processed into a rigid body in vehicle dynamics simulation but for the high speed train the impact resulting from the elastic vibration of the wheelset on the vehicle system vibration characteristics can not be ignored. The paper introduces the flexible dynamics method in the trailer wheelset vibration performance and dynamic stress research. The flexible model of wheelset is set up using substructure method in ANSYS Code and the whole vehicle system dynamics model is obtained by SIMPA… Show more
