Abstract
The structure of a high speed passenger car bogie is designed. The lateral semi-active damper for the secondary suspension is introduced . The stress of the bogie frame is analyzed by the use of finite element method in order to meet the requirement of strength at high running speed. The dynamic simulation of the bogie is undertaken and the ride performance of the bogie with passive damper and semi-active damper are compared. Finally, the roller rig test for the dynamic performance of the bogie prototype is carried out and the theoretical work is validated.
