Abstract EN
In order to reduce the ground-borne vibration caused by wheel/rail interaction in the ballastless track of high speed railways, viscoelastic asphalt concrete materials are filled between the track and the subgrade to attenuate wheel/rail force.
A high speed train-track-subgrade vertical coupled dynamic model is developed in the frequency domain.
In this model, coupling effects between the vehicle and the track and between the track and the subgrade are considered.
The full vehicle is represented by some rigid body models of one body, two bogies, and four wheelsets connected to each other with springs and dampers.
The track and subgrade system is considered as a multilayer beam model in which layers are connected to each other with springs and damping elements.
The vertical receptance of the rail is discussed and the receptance contribution of the wheel/rail interaction is investigated.
Combined with the pseudoexcitation method, a solution of the random dynamic response is presented.
The random vibration responses and transfer characteristics of the ballastless track and subgrade system are obtained under track random irregularity when a high speed vehicle runs through.
The influences of asphalt concrete layer’s stiffness and vehicle speed on track and subgrade coupling vibration are analyzed.
