The present joint research deals with the evaluation of the running dynamics and contact mechanics of two different freight bogies, the “standard” Y25 and the innovative 4L. The behavior of this lightweight bogie is compared to the Y25 using several track irregularities, to analyze the effect of a new primary suspension arrangement and its track friendliness. Stationary and transient vertical response of the bogies are used as relevant parameters for irregularities on tangent track at the maximum speed and different loading conditions. The paper also focuses on the impact of the new bogie when running on switches in both diverging and through directions.

Abstract
The present joint research deals with the evaluation of the running dynamics and contact mechanics of two different freight bogies, the “standard” Y25 and the innovative 4L. The behavior of this lightweight bogie is compared to the Y25 using several track irregularities, to analyze the effect of a new primary suspension arrangement and its track friendliness. Stationary and transient vertical response of the bogies are used as relevant parameters for irregularities on tangent track at the maximum speed and different loading conditions. The paper also focuses on the impact of the new bogie when running on switches in both diverging and through directions.File | Dimensione | Formato | |
