“…The change of load in such a range induces changes of the stiffness parameters which are not considered up to now in papers devoted to the dynamic wheel-rail interaction, that is [5,6]. In the very beginning, let us consider results of measurement of wheel stiffness, wheel-plate stiffness, and wheel-rail contact stiffness obtained in the range 0-100 kN done on the special test stand shown in the Fig.…”

The paper is devoted to the experimental, theoretical analysis and computer simulation of influence of elastic properties of contact stiffness and wheel-plate stiffness on the forces of vehicle-track interaction. Three types of wheels are considered with different contact stiffness and wheel-plate design. Exemplary simulation of freight car interaction with track which posses one corrugated rail for each type of wheel is presented.

Abstract. The dynamic performance of the empty case is worse than the loaded case to the railway freight vehicle in general. The gap damping idea is referred to be used to improve the ride index of the three piece mid-cross bogie vehicle when the friction damper force is downed in this paper. It covers stable security and vibration performance of the model and its parameters of the vehicle with gap resistance controller. There has an apparent difference between the empty case and the loaded case. Especially the vertical performance of the empty case will become worse with the relative friction coefficient largely decreased. The worse performance results from that the vibration energy will increase, and the relative friction coefficient will be lowed down in some degree and the resistance is not to damp the vibration when the speed is increasing to a certain value.

“…Another hybrid model was presented by Nielsen et al [14] for predicting ground vibration due to discrete wheel-rail irregularities. The DIFF model [15], which is based in the time domain, was used to obtain the transient wheel-rail contact force and the TRAF-FIC model [16], formulated in the frequency-wavenumber domain, utilised this as input to predict the track and ground vibration. The ground was included in DIFF using discrete spring-dashpotmass systems tuned to minimise the differences in the track receptance computed using DIFF and TRAFFIC.…”

This paper presents a methodology for studying ground vibration in which the railway track is modelled in the space-time domain using the finite element method (FEM) and, for faster computation, discretisation of the ground using either FEM or the boundary element method (BEM) is avoided by modelling it in the wavenumber-frequency domain. The railway track is coupled to the ground through a series of rectangular strips located at the surface of the ground; their vertical interaction is described by a frequency-dependent dynamic stiffness matrix whose elements are represented by discrete lumped parameter models. The effectiveness of this approach is assessed firstly through frequency domain analysis using as excitation a stationary harmonic load applied on the rail. The interaction forces at the ballast/ground interface are calculated using the FE track through-ground coupling in the lumped parameter model, which has been found to be necessary for both track dynamics and ground vibration predictions.
