A mathematical model to study railway track dynamics for the prediction of vibration levels generated by rail vehicles
(2012-01)
Article
Open AccessThis article presents a mathematical model aimed at predicting wheel–rail contact vibration force arising from wheel profile irregularities. Prediction of vibrations caused by a passing train is a basic factor in environmental ... -
