| Abstract: | 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. |
