Equivalent conicity

The dynamic interaction between railway vehicle and track is fundamental to ensure a safe and efficient operation and maintenance of the railway and can be described by using equivalent conicity. A high equivalent conicity increases instability/hunting, infrastructural damages and the risk of derailment and is therefore a vital parameter to monitor for optimization of maintenance schedules.

Know the geometric interaction between wheels and rails

  • Optimize reprofiling maintenance schedule
  • Identify critical speed limits
  • Reduce risk of derailment
  • Improve vehicle stability
  • Reduce maintenance costs

Calculations

Contact points

The contact points is a graph showing where all the contact between the wheel and rail profiles were found.

Contact angles

The contact angles shows a graph of the left and right contact angle and the difference between the left and right angle relative to the wheelset displacement.

Rolling radius difference

The rolling radius difference shows a graph of the difference rolling radius relative to the wheelset displacement.

Equivalent Conicity

The equivalent conicity shows a graph with the conicity plotted relative to the wheelset displacement.

We’re excited to be part of iaf 2025 in Münster, Germany! Join us at stand M-320 in Halle Mitte, where we’ll be showcasing the MiniProf profile measuring systems in action. Whether you’re an old friend or a new face, we’d love to connect. Stop by for a live demo and a chat about how MiniProf can support your work.

Our Director of Railway Division Mr. Benny Andersen and Area Sales Manager Ms. Dorte Overmark Rasmussen will be there to assist you. In order to schedule a meeting in advance, do not hesitate to contact us.

Should you be attending Railway Interchange in Indianapolis, USA, we invite you to stop by MiniProf agent KLD Labs – an ENSCO company at booth 3015, where you can explore the MiniProf systems and the advanced Envision software.

Uncover the benefits of the highly secure and dependable MiniProf full-contact profile measurements and learn how the Envision software can enhance your everyday operations. Feel free to arrange a meeting beforehand by contacting the KLD MiniProf team.

How can we assist you?

The MiniProf team is here for you! If you have any questions about our MiniProf products, Envision software, Criterion for Android, local agent details, re-calibration or any of our other services, do not hesitate to contact us – we will be pleased to assist.
