Abstract

This paper made a deep research on the axle-box suspension dynamic stiffness characteristics. And testing models including vertical, transversal and longitudinal and solving method based on stepping swept sine excitation were put forward. Then, experiment was taken on a certain bogie, and curves of frequency-stiffness were obtained based on the evaluation method for the dynamic parameters. The results of this paper play a positive role to parameter matching and dynamic simulation.
