Experimental and Theoretical Study on the Dynamic Performance of Steering Bogie in Sharp Curve

Abstract

Bogie trucks for urban railway use are necessary to have not only excellent curving performance but also high speed hunting stability. From theoretical study, full scale stand test and commercial line run, we successfully created a new high-curving-performance bogie with optimized new tread profile. The design concept of new bogie, such as tread profile, suspension stiffness, etc., is described in the first part of this paper. Experimental and theoretical analysis of the comparison between the new bogie and conventional bogies are explained.
