| Popis: | Vehicle/track/bridge interaction causes additional stresses in CWR on the bridge, which include stress in rails due to temperature changes in the bridge deck, vertical bending of bridge deck, and braking/acceleration of railway vehicles on the bridge deck. Critical analysis of additional tensile stresses in CWR on the bridge using Smith diagram was performed and presented in this paper. Furthermore, results of rail temperature measuring at several monitoring locations in Serbia were presented. The influence of the local climate conditions and neutral rail temperature on the temperature stress in CWR was analysed. The paper points out that the prescribed values of additional stresses in CWR have to include influence of real local climate conditions on track stability on the bridge. |
