The Dynamics Studies of a Four-Axle Bogie of Locomotive

Abstract:

A type of bogie structure was proposed for the eight-axle locomotive, of which the middel bogie forme was used to connect the two B0 bogie and support the car body with three suspensions. A single drawbar connect the B0 bogie and car body directly to transfer the longitudinal forces. This structure is simple and feasibility, which can achieve high adhesion availabillity and good dynamic performances. Three suspension can achieve a excellent stability of car body. Comparing with a same speed and axle load class 2C0 locomotive, the wheelset lateral force and wheel rim wear factor are reduced by about 35% at the R300m small radius curves, and the wheelset lateral force is decreased by 15%, and the rim wear factor is reduced by 23% at the R800m curves.
