Dynamic 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 کاملStudy on Braking Panels in High Speed Trains Using CFD
With speed increasing in high-speed trains, due to limitations of other types of brakes, aerodynamic brake has become an important braking method. In this task to make better use of brake’s panel different configurations are examined and the best panel shape which provides the reasonable drag coefficient is introduced. The results of simulations are carried out with the computational fluid dyna...
متن کاملDynamic 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 کاملCFD Simulation of High-speed Trains: Train-induced Wind Conditions on Trackside Installations
Speed is the created air flow as well as slipstream effects as the trains move. These effects can have some level of impact on fuel and energy efficiency of the train, but their other important outcome is the emergence of turbulent flows at higher speeds which can cause aerodynamic drag forces followed by noise and vibration. Thus, slipstream effects have significant importanc...
متن کاملA Review of Recent Studies on Simulations for Flow around High-Speed Trains
Fluid flow around bluff bodies occurs in numerous fields of science and engineering, such as flows pass vehicles, cables, towers and bridges. These flows have been studied experimentally and numerically for the last several decades. The investigation of flow around high-speed trains is an important application of bluff bodies. Fluid flow, aerodynamic forces and moments, separation and wake regi...
