Research on Finite Element Model of Wheel-Rail Contact

Article Preview

Abstract:

Many researchers applied creepage to calculating creep force, but relation between creepage and creep force are very complex and it has been a major problem for solving rolling contact theory. The paper uses the finite element method for studying directly creep forces and apply it to the studies of wheel-rail rolling contact. Paper establishes the finite element model of wheel-rail rolling contact based on ALE method in ABAQUS, and simulated unsteady state of wheel-rail rolling contact and research normal force of wheel-rail contact pitch. Results show that the normal maximum pressure in left wheel have a trend toward the center of contact pitch and the normal maximum pressure in right wheel have a trend toward the other center of contact pitch with increasement of displacement
