Construction of Contact Model of Wheelset Assembly Surface Based on ABAQUS

Abstract:

In order to improve quality of wheelset assembly, a method for calculating interference between two sliding asperities that corresponding to the wheelset assembly interference is presented. A finite element model of sliding spherical asperity has been built with the finite element software ABAQUS to analyze the interaction among mating surface roughness, stress-strain state and press-fit curve. This study shows that final fitting force greatly increases with roughness when roughness is lower then 1.8μm and it is unpredicted when roughness is higher. Contact stress and friction coefficient between mating surfaces increase with roughness.
