Investigation of rail track vibration due to fractured sleepers [PDF]

International Journal of Advanced Design and Manufacturing Technology, 2012
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.

Effect of Intermediate Elastic Support on Vibration of Functionally Graded Euler-Bernoulli Beams Excited by a Moving Point Load

Journal of Asian Architecture and Building Engineering, 2017
The effect of intermediate elastic support on the vibration of functionally graded Euler-Bernoulli beams excited by a moving point load is studied. The material properties of the beams are assumed to vary in the thickness direction of the beams by a ...
