What is Wheel-Crossing Impact Model Analysis about?

This document summarizes a finite element model of a wheel passing over a railway crossing. The model accounts for dynamic impact and contact forces between the wheel and crossing, as well as elastic and plastic deformation of the crossing. The model can calculate contact pressures, microslip, frictional work, and power dissipation to evaluate damage like wear and cracking. Results are presented for different train velocities in both directions when the wheel moves from the wing rail onto the nose of the cr
