Abstract

An explicit 3D finite element model of a comprehensive railway track is established. Using this model, a study is performed which focuses on supported track systems. Within the model variations in the stiffness of rail pads and under sleeper pads are investigated which induce changes in vertical forces acting on the rail surface and influences the wheelset movement. By applying an angle of attack to the wheelset the lateral forces are influenced and calculated. Using varying track parameters, the impact of rail pad stiffness, under sleeper pad stiffness, and angle of attack on critical variables such as maximum contact pressure, vertical and lateral forces and displacements is shown. This theoretical understanding facilitates an optimized design of the track system and its interacting parameters.
