Abstract

La invención se centra en una metodología y en medios de aplicación de sensores extensométricos, en combinación con equipos electrónicos y un post-proceso de las señales y datos obtenidos, para medir esfuerzos en vías de ferrocarril y similares, asi como para medir fuerzas de contacto entre la rueda del vehículo o tren y el propio carril por el que circula. Según el método, se procede a: capturar microdeformaciones en un punto conocido de la vía; analizar esas microdeformaciones; identificar el elemento correspondiente al pico de señal de las microdeformaciones coincidente con el paso del tren por encima de una de las traviesas de la vía; analizar la señales de los picos de las microdeformaciones identificadas anteriormente; obtener señales mediante unos sensores (5) dispuestos en pletinas (6) atornilladas al carril (7), procediendo finalmente a calibrar cada pico de microdeformación detectado y su relación con las magnitudes que se desea medir.
