A novel idea for predicting the equivalent conicity is presented, based on the inclinations of the wheel thread at the running circle and the rail profile at top-of-rail.

    Both the shape of the wheel profiles and the shape of the rail profiles can be acceptable in today’s standards, but together the wheel/rail profile combination can lead to an unacceptable high value of the equivalent conicity, which can make the vehicle unstable. By introducing two gradient indices, one for the wheel and one for the rail, it is possible to separate the equivalent conicity into two parts, which also make it possible to put limit values on wheel and rail profiles separately. The indices are combined into a joint index, GIP. The new GIP index is compared to the equivalent conicity for a large number of worn rail and wheel profiles, and show promising results.
