Abstrakt:

In this study a procedure to obtain contact points and its characteristics is given. Widely used S1002 and UIC60E1 profile is used as an example to illustrate the proposed methodology. Firstly wheel/rail geometry is presented along with the calculation of contact points by considering roll angle of the wheelset. Afterwards a more realistic contact search method, namely quasi-elastic contact search, is presented. Lastly, the determination of the Hertzian contact patch is shown in details by giving numerical solution to elliptical integrals.
