Abstract
A 3D finited element method contact model of wheelset and track is constructed, in which locomotive and vehicle wheelset are respectively considered. The wheel/rail 3D elastic-plastic contact problem is analyzed by using the parametric finite element method and quadratic programming method. Results, such as the wheel/rail contact force, contact status and wheel/rail stress distribution, are obtained. Difference in wheel-rail contact between locomotive and vehicle is discussed. The problem of two-point contact resulting from wheel flange close to rail is analyzed.
