Equivalent conicity

Equivalent conicity is a mesaure of wheel/rail contact conditions. It is described by the standard EN15302 (earlier UIC519).

Paul Dreik participated in the verification of the standard and has since then worked with several related projects.

  • an octave/matlab toolbox for calculate equivalent conicity from arbritrary wheel and rail profiles. The toolbox can also calculate radial steering index.
  • a c++ program which calculates equivalent conicity from measured rail profiles

The licensing of the toolbox allows Dreik Ingenjörskonst to calculate conicity with it.
