7. 5. Train–Track–Bridge Interaction for the Analysis of Railway Bridges and Train Running Safety

   Författare :Therese Arvidsson; Raid Karoumi; Andreas Andersson; Costin Pacoste; Guido De Roeck; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamics; railway bridge; bridge deck acceleration; train–bridge interaction; vehicle model; wheel–rail force; running safety; Civil and Architectural Engineering; Byggvetenskap;

   Sammanfattning : In this thesis, train–track–bridge interaction (TTBI) models are used to study the dynamic response of railway bridges. A TTBI model considers the dynamics of the train in addition to that of the track–bridge system. The TTBI model enables the assessment of train running safety and passenger comfort. LÄS MER
