Abstract

This paper shows a procedure to determine the mechanical properties of a simple track flexible model to be used in the multibody simulation of railway vehicles. The procedure is based on the frequency response function of the track in the range of frequencies in which the simple model is desired to be used. This work applies, as an example, the proposed procedure to a scaled railroad track available at the Authors’ facilities with a 10-DOF simple track model showing its applicability, range of operation, and ease of implementation, which can be easily extended at full-scale tracks with similar simplified track models.
