Tire modelling guru Professor Pacejka pays a visit to Cruden

Legendary academic drives his own Pacejka tire model 6.0 in a GT3 race car on a Cruden Hexatech 6-DOF motion simulator.

AMSTERDAM, The Netherlands – Renowned vehicle system and tyre dynamics expert, Professor Hans Bastiann Pacejka (80), paid a special visit to Cruden in April. The Professor emeritus at Delft University of Technology in Delft (Netherlands) drove a few laps of the Zandvoort circuit in a GT3 Porsche model developed by Cruden, on one of the company’s 6-DOF Hexatech motion simulators.

Despite being the name behind the ‘magic formula’ which defines the tire models relied upon by vehicle dynamics and simulation engineers globally for the past 20 years, Professor Pacejka has rarely driven vehicle simulators. He was tempted to try out the Cruden simulator at the invitation of two of his former students, Cruden’s CEO Maarten van Donselaar and senior modeling and simulation engineer, Edwin de Vries.

De Vries was assistant professor to Professor Pacejka between 1994 and 1998 where the two co-developed the Delft motorcycle tire model. He commented, “In the simulation world, this is the equivalent of a visit from royalty. We think the delight was two-way as Professor Pacejka was very happy to see his work still alive and kicking and being used for the benefit of motorsport and automotive customers all over the world. He particularly liked our so-called ‘Pacejka-player’ that we use to visualize the effect of parameter changes on tire force response, as part of our Racer Pro simulator software. He definitely wanted to have this software.” 

Pacejka tire models are widely used in professional vehicle dynamics simulations, and racing car games, as they are accurate and easy to program. They pose a very limited demand on computational power so that vehicle model driving runs easily in real-time.


About Cruden

Cruden is the world’s leading designer and manufacturer of professional, interactive, motion-based racing simulators. The company develops the most high tech, realistic and accurate professional equipment for the top levels of international motorsport, including Formula 1, as well as vehicle manufacturers and their suppliers. The same package is then made available to the global attractions market and to private individuals to create a motorsport experience which simply does not compare with ‘games’ machines on the market. Cruden’s heritage is in the development of professional simulators for the aerospace, marine and automotive industries. Originating from Fokker Aircraft Company, the company was FCS Racing Simulation before becoming Cruden in 2006. www.cruden.com
