Equivalent conicity

The equivalent conicity is a key parameter for the running behavior of rail vehicles. It describes how a wheelset moves on the rail and directly influences the running characteristics, stability and wear of wheels and rails. Precise calculation of this value is essential in order to minimize safety risks and maximize the service life of wheelsets and infrastructure.
