Dynamics Analysis of Wheel Rail Contact Using FEA

AbstractA rail wheel contact mechanism has been a keen interest area for railway engineers. The present study focuses on the influence of interacting wheel and rail profile topology. A standard rail UIC 60 and standard wheel profile, as per the standards of Indian railways, were taken for different rail profile radii, wheel profile radii and wheel profile tapers. The mathematical and numerical studies were done by using Quasi–Hertz and FE analysis to analyze the impact of the interacting wheel and rail profiles on the distribution of contact zones and stresses. Moreover, the effect of contact forces and contact stresses on the deformation of rolling wheels and rails were also evaluated. The effect of lateral movement in the evaluation of frictional forces was found using Kalker theory
