Dynamic analysis of high speed railway bridge under articulated trains
The problem of vehicle–bridge dynamic interaction system under articulated high speed trains is studied in this paper. A dynamic interaction model of the bridge-articulated train system is established, which is composed of an articulated vehicle element model and a finite element bridge model. The vehicle model is established according to the structure and suspending properties of the articulat...
متن کاملDynamic Analysis of Railway Bridges under High Speed Trains
The interest in dynamic behavior of railway bridges has increased in recent years with the introduction of high speed trains. Higher speeds of the trains have resulted in larger and more complicated loads than earlier, producing significant dynamic effects. The dynamic aspects are of special interest and have often shown to be the governing factor in the structural design. Dynamic analysis of r...
متن کاملMulticriteria Optimisation of Railway Track for High-speed Lines
The paper presents results of multicriteria optimum design of an embedded rail structure (ERS). The optimality criteria are based on the requirements to railway tracks related to cost efficiency of the design, minimum noise emission and minimum wear of wheels and rails. The design variables comprise the material and geometry properties of ERS, namely elastic properties and volume of compound, s...
متن کاملTwo-station single-track railway scheduling problem with trains of equal speed
In this paper, the single-track railway scheduling problem with two stations and several segments of the track is considered. Two subsets of trains are given, where trains from the first subset go from the first station to the second station, and trains from the second subset go in the opposite direction. The speed of trains over each segment is the same. A polynomial time reduction from the pr...
