dc.descriptionThe dynamic response of a railroad vehicle is affected by the frictional forces generated at the wheel-rail contact surface. The friction in the wheels consist of tangential collisions with the rail that affect the vehicle dynamics, which can be measured using the vehicle's vibration level. In this study, the vibrations of a scaled-down railway vehicle undertaking a braking maneuver are monitored to determine the coefficient of friction at the wheels. The 1:20-scale rail vehicle is equipped with encoders, accelerometers, and a Bluetooth control. The tests are conducted on both a clean and on a friction-modified railway. To relate the level of vibration measured in each test with high or low coefficients of friction, suitable statistical indices were selected. Furthermore, and using a correlation algorithm based upon the Continuous Wavelet Transform (CWT), it is demonstrated that frictional forces are transmitted to the vehicle body. The output data indicate that the vibrations characteristics depend on the wheels’ coefficient of friction, which can be used to classify it as a high or a low friction, and that it is possible to study the tangential forces during braking using the vehicle's vibrations.es_ES
