摘要
本文对铁路轮轨系统动力学建模进行了综合分析与研究。简要回顾了轮轨动力分析模型的演变历程，并对各种分析模型作了基本分类。通过对模型结构特点、模拟功能与计算精度的分析比较，指出其各自的优缺点及适用范围，为轮轨系统中各类具体问题的建模与选模提供有益参考。文章还将新近发展的轮轨耦合系统统一模型与若干传统模型进行综合对比，从而阐明了轮轨动力分析模型的发展趋向。
This paper discusses the modelling of the wheel/rail dynamic system.The development of the analytical models for wheel/rail dynamics is briefly reviewed,and all types of wheel/rail interaction models are systematically classified. Advantages and disadvantages ofeach model, together with its applicability, are pointed out based on the comparison of itsstructural characteristics, modelling functions,and numerical accuracy. Conclusions obtained are very helpful for the modelling of all dynamic problems in the wheel/rail interaction system. Finally, a new unified model is specially introduced so as to demonstrat the developing trend of the analytical models for wheel/rail dynamics.
