Abstract

In the following text, the influence of the stiffness of rail fastening systems of high-speed railway lines on the dynamic stability of a vehicle travelling along a straight track is investigated. The dynamic behaviour of the rail head in lateral direction is incorporated in the model by means of mechanical models derivedfrom a preceding frequency analysis of the track. For the wheel-rail interface, linear contact mechanics and kinematic relations are applied. The investigation leads to the conclusion that on high-speed lines the critical velocity of vehicles is reduced as a result of the increased elasticity of the rail pads.
