Summary
In this paper, a comparison between numerical and experimental results of a 5 inch scaled railway vehicle running on a scaled track is reported. The design and main features of the scaled vehicle are presented together with its instrumentation, which is formed by inertial measurement units and distance lasers. Also, a simplified numerical model of the scaled vehicle is proposed together with the specification of the experimental tests. The purpose of this work is to check the accuracy of the models when real experimental data is available. Thus, to accurately compare results, the railroad track is measured every 20 mm for each rail to determine its irregularities, in which vertical and lateral deviations with respect to the ideal position of the left and right rails are identified using an accurate and innovative procedure.
