Vibration Characteristics and Effectiveness of Floating Slab Track System
Ground-borne vibration excited by metro traffic is becoming a more and more important problem for the rapidly developing transport system in urban areas and increasing public concern about environmental problems. In order to attenuate the vibration influence down to an acceptable level, floating slab track have been applied worldwide on metro line. An analytical dynamic model is employed in thi...
متن کاملInfluence of slab length on dynamic characteristics of subway train-steel spring floating slab track-tunnel coupled system
A subway train-steel spring floating slab track-tunnel coupling dynamic model, considering short and middle-long wavelength random track irregularities, and longitudinal connection between adjacent slabs of steel spring floating slab track, was developed. And the influence of slab length on dynamic characteristics of the system under different track conditions and train speeds are theoretically...
متن کاملParameter Influences of Light Floating Slab on Its Vertical Vibration Excited by Track Irregularity
According to the structure characteristics of railway viaduct with light floating slabs, a frequency domain dynamic model of the vehicle-light floating slab track-viaduct bridge vertical coupling system is established. The Green functions are used to quickly calculate the receptance response of the system, and then the pseudo excitation method is used to further analyze the parameter influences...
متن کاملFloating Track Slab Systems for Reducing Ground- Borne Noise and Vibration from Rail Vehicles
This investigation explores both the theoretical and empirical modelling of the dynamic performance of floating slab track systems used for reducing groundborne noise and vibration from rail transit systems. Accurately predicting the performance of floating slab track systems is important to the success of a new rail project. In general it has been observed that analytical and numerical models ...
متن کاملDynamic Response of the Coupled Vehicle-Floating Slab Track System using Finite Element Method
In present study, a mathematical model of the vehicle–floating slab track (FST) interaction is established to investigate the coupled behaviour of vehicle–track system. The FST is modelled as the double Euler -Bernoulli beam including the rail and slab. The railway vehicle is simplified as a multi-rigid-body model. The wheel–rail interface is treated using a nonlinear Hertzian contact model, co...
