To investigate railway impact noise caused by discrete rail or wheel irregularities, such as wheel flats, rail joints, switches and crossings, a time-domain wheel/rail interaction model is needed. However, time-domain models are normally time consuming to solve and this makes it difficult to carry out parametric studies and gain insight into physical behaviour. A simple mass-spring equivalent track model is developed here to gain insight into the impact vibration induced by a wheel flat irregularity. With the track system simplified to only three degrees-of-freedom, the calculation times of the wheel/rail interaction simulation are reduced by a factor of 10 compared to a corresponding finite element track model. Using this very efficient time-domain wheel/rail interaction model, the characteristics of impact noise in the audio frequency range due to a wheel flat are studied.
