Abstract

The dynamic behaviour of a railway vehicle is mainly depending on how the interaction of wheel and rail is taking place in running operation and what is the accuracy and efficiency of the applied contact models. Contact mechanics of railway vehicle is keyed with the history of the wheel-rail contact mechanics. For a designer of braking and traction control systems, it is essential to go through the fundamental knowledge of forces produced due to contact of wheel-rail and geometric constraints as well as moments to assess the wheel-rail wear and to evaluate the ride performance indices. This article gives a brief review to the evolution and present scenario of the previously published contact theories to get rid of the wheel-rail contact problems. The key theories which have most attention to solve normal contact problems are Hertzian contact theory as well as non-Hertzian contact theory, whereas, to tackle the problems related to tangential contact, linear as well as non-linear theories proposed by Kalker, theory proposed by Polach, FASTSIM, CONTACT etc are considered in this paper. This paper reviews the state-of-the-art of past studies based on experiments to study various contact models.

轨道车辆轮轨接触力学研究进展

轨道车辆的动力性能主要取决于轮轨在运行过程中的相互作用以及所采用的接触模型的精度和效率。轨道车辆的接触力学与轮轨接触力学的发展历史密切相关。对于制动和牵引控制系统的设计者来说，了解轮轨接触产生的力和几何约束以及力矩的基本知识对于评估轮轨磨损和评估行驶性能指标至关重要。本文简要回顾了为解决轮轨接触问题而提出的接触理论的发展历程和现状。解决法向接触问题最受关注的关键理论是赫兹接触理论和非赫兹接触理论，而解决切向接触问题，本文考虑了Kalker提出的线性和非线性理论，Polach, FASTSIM, contact等理论。本文在对各种接触模型进行实验研究的基础上，综述了以往的研究进展。
