• Wheel/Rail Contact

In this paper, the wheel/rail 3D elastic-plastic contact problem is analyzed and solved by using the finite element parametric quadratic programming method (FEPQPM), which is based on the parametric variational principle. And the multi-substructure technique is also used. The 3D FEM models of cone-tread and worn-tread locomotive wheels are firstly established, which come into contact with the rail of standard size. A lot of data such as the wheel/rail contact force;contact status and wheel/rail stress distribution are obtained. After detailed analysis of the computational results, discussions are made on how the structures of locomotive and vehicle as well as some applied parameters influence the performance of wheel/rail contact.
