The Dynamics of a Railway Wagon Wheel-set with dry Friction Damping |

| Abstract | Dry friction dampers have been used in car constructions for several hundred years, and are still extensively used by the railways today. The main reason is that they are much cheaper than hydraulic dampers and more rugged. Their disadvantages are that their function is variable and depends on weather conditions and their state of contamination (dirt, oil) and last but not least the state of wear. The designers have used old empirical rules for the application of dry friction dampers in railway vehicles. This contribution will help to unveil the dynamics of a suspension system containing a coupling between a dry friction damper and the basic nonlinearity in railway dynamics - the rail-wheel contact forces, which act as a nonlinear softening restoring force. |
