Roadcloud's webinar series on road friction and tyre grip
RoadCloud started as a university startup, based on many years of research in tyre friction, vehicle dynamics and road surface. We now want to invite you back to the classroom and the blackboard. Join the unique opportunity to refresh or learn the essentials of road friction and tyre grip, explained and presented to you by RoadCloud’s own PhDs specialised in the area. The content of the webinars is held on a basic level, so no background in any particular topic is needed. However, there’s plenty of room for deep-diving for the interested. In this three parted webinar series we’ll cover these areas:
- Part 1: What is Tyre Road Grip Made of? Brief introduction to multi-scale friction, presented by Mona Kanafi and Ari Tuononen
Part 2: From Local Friction to Tyre Grip – Force Generation Process, presented by Arto Niskanen and Ari Tuononen
- Part 3: Tyre-Road friction estimation in practice, presented by Arto Niskanen and Ari Tuononen
Access all three webinars by signing up below.
Speakers
What is tyre road grip made of?
Brief introduction to multi-scale friction
Presented by: Mona Kanafi, Ari Tuononen
Key takeaway:
- Understand Multi-Scale Roughness & Rubber Hysteresis Interaction
Mona and Ari will cover the topics of multi-scale rough surface, rubber sliding velocity compared to frequency, speed dependency of sliding µ, rolling resistance example, and why RMS is not enough.

Part 2:
From Local Friction to Tyre Grip – Force Generation Process
Presented by: Arto Niskanen, Ari Tuononen
Key takeaways:
- Brush model tyre: Static and sliding friction in rolling tyre
- Tyre contact patch shear stresses in low and high friction condition
Part 3:
Tyre-road friction estimation in practice
Presented by: Arto Niskanen, Ari Tuononen
Key takeaways:
- Micro-slip in the tyre contact patch
- Slip slope lottery and friction potential
- Vibrations as an opportunity to predict friction
- Optical sensing
