Experimental Validation in a Controlled Environment of a Methodology for Assessing the Dynamic Behavior of Railway Track Components

This article presents a novel methodology conducted under controlled laboratory conditions to assess the dynamic behavior of components railway tracks by applying an unbalanced mass excitation force. The for obtaining accurate measurements, which uses different parameters, is based on device, and from these data, transmissibility mass-elastomer system estimated. For assessment behavior, sine sweep rate excitations, mass, background noise are considered. experimental measurements with shaker device performed validate methodology. this, frequency-by-frequency swept were shaker, 1 51 Hz, using rates mass. results obtained allow comparison at specific frequencies parameters device. Thus, estimation error rate, developed. By proposed methodology, it possible lower estimated noise.
