Algorithm for Wheel Rail Contact Geometry

  • Publish Date: 25 Apr 2003
  • An algorithm for wheel rail contact geometry is proposed, which can detect single and multi-contact rigid patches, or loss of contact of wheels with rails in dynamic simulation of railway vehicles. The rigid contact patches are the bases to determine the penetration and curvatures for the Hertz theory, the normal gap of the contact zones for non-Hertz theory, and the center and normal direction for dynamic simulations. The validity of the proposed algorithm is verified with 3D OpenGL graphs, and the algorithm has been applied to the development of simulation software for full 3D vehicle system dynamics.
