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 SIMPACK Code. The vibration behavior of wheelset and the wheel-rail forces are presented and then the dynamic stress of the axle is analyzed. 300 km/h EMU online test is carried out and the result comparison between the testing data and data from simulation shows the reliability and feasibility of the dynamics model proposed.
