Hertzian Contact Stiffness

In dynamic wheel/rail models, the Hertzian contact stiffness is an important parameter. A track structure and wheel set connected by means of a Hertzian spring is used to describe high frequency vertical vibrations. Unfortunately the Hertzian contact stiffness has been a subject of some dispute by various authors e.g., Hertz, Jenkin, Ahlbeck, Roark, etc. The paper uses Bousinesque equation for vertical deformation of rail under the center of a circular loaded surface to derive a linearized Hertzian contact stiffness formula and compares different approaches available in literature. The values obtained from proposed formula are compared with the values from literature for the purpose of validation.
