摘　　要：简单论述世界铁路发展状况和铁路交通运输的优越性。详细论述轮轨关系的研究问题,其研究包含轮轨滚动接触作用和稳定性问题、轮轨粘着和强度、接触表面磨损和滚动接触疲劳破坏、轮轨噪声、轮轨蠕滑率力理论和轮轨三维弹塑性滚动接触问题。在这些问题研究中,蕴涵十分复杂的力学和强度问题。文中就这方面的研究现状和存在问题以及问题研究的难点进行讨论,并分析今后可能的研究方向。Abstract Development history, advantages and future trend of railway tragic in the world are briefly introduced. The studies onthe performances of wheel and rail are described in detail. They are classified as the stability and derailment of wheel and rail systems,adhesion and strength between the contacting surfaces, wear and fatigue of wheel and rail in mlhng contact, creep-force theory and roll-ing contact theory of wheel and rail in elastic-plastic deformation. These studies concern with the complicated mechanics. Some con-cerned important papers pubhshed in the past are reviewed, and the existing difficulties in the studies are discussed. Finally, the poten-tial directions to attack these hard tasks in the future are presented.
