On the vertical interaction between a three-axle bogie and track

In this paper, the ‘moving wheel’ model is used aiming to analysis new aspects of the interaction between three-axle bogie and track due to the harmonic roughness of the rail. The three-axle bogie of a locomotive is considered and its model is reduced to three loaded wheels running along a rail supp...
