Trackbed behavior analysis based on distributed acoustic sensor

Trackbed behavior analysis based on distributed acoustic sensor
Trackbed behavior analysis based on distributed acoustic sensor
In this study, an optical fiber, buried in the trackbed during track renewal, is used to measure the vertical support and pressure distribution of the track. The pressure distribution was obtained using a distributed acoustic sensor (DAS) system by measuring the pressure-induced strain changes on the sensing fiber. The experimental results obtained by the DAS system show a good agreement with the numerical model of the trackbed.

Abstract

In this study, an optical fiber, buried in the trackbed during track renewal, is used to measure the vertical support and pressure distribution of the track. The pressure distribution was obtained using a distributed acoustic sensor (DAS) system by measuring the pressure-induced strain changes on the sensing fiber. The experimental results obtained by the DAS system show a good agreement with the numerical model of the trackbed.
