Impact of Yaw Motion of Wheelset on Wheel-Rail Contact Creepage

Abstract:

Many researchers applied creepage to calculating creep force, and relation between creepage and creep force are very complex and it has been a major problem for solving rolling contact theory. The paper established the finite element model of wheel-rail rolling contact based on ALE method (Arbitrary Lagrange-Euler method) in ABAQUS, and research impact of yaw motion of wheelset on creepage of wheel-rail contact. Results show that in the yaw movement there are small fluctuations in elastic longitudinal creepage; elastic lateral wheel creepage of left and right wheel appear different, there are small change after yaw angle beyond 2 mrad; spin creepage of left and right wheel have not change with increase of yaw angle
