本文综述了铁路轨道的动力学建模以及车辆和轨道在足够高的频率下的相互作用，这些频率对轨道的动力学行为具有重要意义。由于噪声是高频下轮轨相互作用的最重要后果之一，因此感兴趣的最大频率约为5kHz：人类听力的极限。该主题是回顾历史，特别是参考应用建模解决实际问题。现在可以为所有感兴趣的频率范围提供良好的钢轨、轨枕和轮对模型。然而，目前不可能预测轨道垫和道碴的动态行为或它们的长期行为。这被认为是未来研究最有前途的领域。
A review is presented of dynamic modelling of railway track and of the interaction of vehicle and track at frequencies which are sufficiently high for the track's dynamic behaviour to be significant. Since noise is one of the most important consequences of wheel/rail interaction at high frequencies, the maximum frequency of interest is about 5kHz: the limit of human hearing. The topic is reviewed both historically and in particular with reference to the application of modelling to the solution of practical problems. Good models of the rail, the sleeper and the wheelset are now available for the whole frequency range of interest. However, it is at present impossible to predict either the dynamic behaviour of the railpad and ballast or their long term behaviour. This is regarded as the most promising area for future research.
