چکیده
Aiming at a large number construction of high-speed railway and elevated railway passenger station, make a dynamics simulation study on the law of platform vibration characteristics on the situation of high-speed train passing through. First, make a brief introduction on the theory of the interaction of the vehicle-elevated station structure in vertical and transverse directions. Secondly, on the background of the actual elevated station structure form, selecting relevant model parameters, establish the train-elevated station coupling dynamics simulation analysis model and calculate it. Finally, based on the calculation results, make an analysis of vibration characteristics of the platform structure, and obtain relevant study conclusions.

Optimal Nonlinear Energy Sink (NES) is employed in vibration suppression of the beams subjected to successive moving loads in this paper. As a real application, a typical railway bridge is dynamically modeled by a single-span beam and a traveling high-speed train is simulated by a series of successive moving loads. Genetic algorithm is employed as the optimization technique and optimal paramete...

High speed trains are an indispensable part of rapid transportation systems in many countries. As the fastest means of transport on the ground, these trains are extremely sensitive to the terrain and track conditions. Geometrical irregularities and mechanical characteristics of the track, together with inconsistencies in the lane (including bridges that support the track) are considered importa...
متن کاملEffect of Rail Corrugation on the Amount of Train Induced Vibrations near a Historical Building
The evaluation and control of the trains induced vibrations needs even more attention in the case of underground tracks which passes near to monuments and historical sites. The rail corrugations which occur due to the wheels’ impulse loads during the operation period of underground railway tracks, usually amplify the ground borne noise and vibration. In the current study, the mentioned phenomen...
