  4. Abstract:
  5. The rail-wheel interactions and their effects on the wagon dynamics has been studied in this article. Also the effects of braking on wagon and rail vibrations are studied. The model consists of a wagon with body, two bogies and four wheels having 21 degrees of freedom in a planar arrangement. The rail system is treated as a Timoshenko beam supported by sleepers, ballast, subballast, and subgrade. To determine rail-wheel contact forces, Hertzian nonlinear contact theory and Kalker theory have been used. The model is simulated for a number of working conditions and the results are validated by comparing to previous works in the literature. Copyright © 2005 by ASME
