Study on New Metro Bogie

The technical levels of the metro bogies at home and abroad are investigated. The design scheme of new metro bogie is put forwarded based on the practical applications of domestic running gears. Through the selection of appropriate dynamic parameters for the bogie, dynamic models for the bogie and vehicle are built with ADAMS/Rail. The curve negotiation performance and riding quality index in straight line is analyzed. The relevant parameters are in accordance with the specifications. Besides, the structures of main components are designed and explained in brief.
