Correlation Analysis between Rail Track Geometry and Car-Body Vibration Based on Fractal Theory

Influences of Railway Track Geometry Parameters on Ground-Borne Vibration

One of the most important challenges in the development of urban railways network is the effects of railway vibrations on human and adjacent structures. Although various investigations into the sources of railway vibrations have been conducted, very few research works have been reported on the influences of track geometry parameters on the level of vibrations. This is addressed in this resea...

Optimal Maintenance and Renewal Strategy Due to Rail Track Geometry

Estimation of track parameters and wheel–rail combined roughness from rail vibration

Rolling noise from railways is significantly affected by the wheel–rail combined roughness and the dynamic properties of the track. To facilitate vibration and noise predictions it is desirable to be able to determine these parameters accurately from field measurements. In this study an inverse method to determine these parameters is adopted and enhanced. Use is made of a track model based on a...

investigation of rail track vibration due to fractured sleepers

in this paper effects of fractured sleepers on rail track vibration under moving wheelset have been investigated. two parallel rails of the track have been modeled as euler-bernoulli beams on elastic points as rail pads. also sleepers have been modeled as visco-elastic euler-bernoulli beams. it is assumed that, some sleepers under the rail track have been fractured and modeled by two beams. the...
