A dynamic simulation of the wheel–rail impact caused by a wheel flat using a 3-D rolling contact model

Abstract A three-dimensional (3-D) wheel-rail rolling contact model with a wheel flat was built using commercial software Hypermesh, and the dynamic finite element simulation was conducted using LS-DYNA 3D/explicit code. Influences of the train speed, flat length and axle load on the vertical wheel-...
