20.500.12556/DiRROS-16327 Development and testing of a railway bridge weigh-in-motion system This study describes the development and testing of a railway bridge weigh-in-motion (RB-WIM) system. The traditional bridge WIM (B-WIM) system developed for road bridges was extended here to calculate the weights of railway carriages. The system was tested using the measured response from a test bridge in Poland, and the accuracy of the system was assessed using statically-weighed trains. To accommodate variable velocity of the trains, the standard B-WIM algorithm, which assumes a constant velocity during the passage of a vehicle, was adjusted and the algorithm revised accordingly. The results showed that the vast majority of the calculated carriage weights fell within %5% of their true, statically-weighed values. The sensitivity of the method to the calibration methods was then assessed using regression models, trained by di%erent combinations of calibration trains. bridge weigh-in-motion railway bridge loading bridge instrumentation B-WIM mostni sistem za tehtanje vozil med vožnjo obtežba železniškega mostu instrumentacija mostu B-WIM true false true MDPI Angleški jezik Slovenski jezik © 2020 by the authors.
