20.500.12556/DiRROS-23488 Railway bridge weigh-in-motion system The paper provides an overview of the development of a railway bridge weigh-in-motion (B-WIM) system, one of the first of its kind for weighing trains in motion. A steel truss bridge in Poland was used for testing the system. Four trains which passed over the bridge were weighed in a rail yard in Warsaw. The conventional road B-WIM system was adapted to calculate the weights of the train carriages using the measured response from the test bridge and the accuracy of the system was assessed. Initial result showed that weights of one of the four trains of known weight were predicted very accurately, but accuracy of the other three trains was poor, with calculated carriage weights deviating by as much as 30% from their actual values. An in-depth analysis showed that these trains were changing velocity as they traversed the bridge and that the large errors were directly correlated to this changing velocity. The standard B-WIM algorithm, which assumed a constant velocity during the passage of a vehicle or train, was adjusted to allow for the effect of this changing velocity. The results improved dramatically, with the vast majority of the calculated wagon weights falling within 5% of their actual values. Further developments tailored the B-WIM algorithm for weighing trains, including the system interface that employs graphics of locomotives and wagons. The development of the railway B-WIM has been a success and has demonstrated that calculations of train weights using instrumented bridges can be efficiently performed. accuracy B-WIM measurement error train weigh-in-motion natančnost B-WIM napaka meritve vlak tehtanje med vožnjo true false true Elsevier Angleški jezik Slovenski jezik © 2016 The Authors Neznano 2025-09-05 07:10:29 2025-09-05 07:19:35 2025-10-24 03:54:25 0000-00-00 00:00:00 2016 0 0 Str. 4010-4019 Vol. 14 2016 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2016-01-01 656.1 2352-1465 10.1016/j.trpro.2016.05.498 17300995 14710043 https://www.sciencedirect.com/science/article/pii/S2352146516305051 1 a50b8148-8a16-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=34739 RAZ_Znidaric_Ales_2016.pdf RAZ_Znidaric_Ales_2016.pdf 1 28E40C225A69F410EC3C18FC8AD04418 e1f4b4b4fe306536d548f6226fccf8100807ea249f5e2831e62b517912485e2c 7186814d-8a17-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=34740 Zavod za gradbeništvo Slovenije 0 0 0
