Equivalent conicity calculation program

Equivalent Conicity is a parameter that is used when investigating dynamic interaction between railways vehicle and track. The parameter describes behavior of contact between wheels and rails for straight and large radius parts of track.

The program calculates the next parameters:

  • contact points position;
  • rolling radiuses difference depending on displacement of wheel set;
  • contact angles and their difference depending on displacement of wheel set;
  • equivalent conicity.

The program can use data from Railway wheel profile gauge IKP-5 and Rail profile measurement gauge PRP or other any sources. The only thing needed is the description of Real Wheels and Rails Profiles presented in tabular form. Detailed instructions in the Manual. 

Calculations are made in accordance with EN 15302.
