Abstract

In the need for more efficient and sustainable infrastructures, a promising solution could be to incorporate sensors for real-time monitoring. In this sense, the present paper focuses on a parametric study into the design of rail pad including piezoelectric sensors, to define the optimal conditions for the manufacturing and application of these smart elements. Particularly, this research aims to develop rail pads with a removable sensor-holder that allows for a versatile track component with capacity to be adapted depending on monitoring requirements, while allowing for future repair of sensor and/or its replacement to adapt future technologies. With this purpose, a series of laboratory tests (traffic load application and simulating train passage tests) were carried out to determine the optimal position of the sensor inside the rail pad and the impact of using a removable sensor-holder. Also, the optimization of the removable sensor-holder was determined, evaluating the thickness of the device, the design method and different types of pads for the insert to be employed. Results showed that the removable sensor could detect load changes and the train passage load, having the advantage of being removed from the pad for data extraction or changing the sensor type, as necessary for future studies.
