Advances on Railway Yaw Damper Characterisation Exposed to Small Displacements
This paper examines behavior of a railway yaw damper when subjected to small displacements. These operating conditions occur on high-speed tracks where a high degree of infrastructure maintenance assures low excitation levels of a vehicle. The dynamic response of the typical spring/dashpot in-series model is compared with experimental results of a damper in a wide range of operating conditions. Correlation of results shows the limitations of this conventional damper model, and some simple modifications are proposed. The variations introduced to produce a 'modified' damper model do not add complexity to the conventional model, but extend the operating range for which it has a good correlation with experimental results.
