The quickest way to faster lap times

Workshop

Magic numbers from racecars

This workshop helps engineers to improve the laptimes by getting a better technical understanding of the handling of their racing car.

The basic idea behind this workshop is the fact that nowadays 99,99% of the competitors in motor racing use an existing car, be it new or used. But the question is how well do you know your car? Do you know the roll moment exact in numbers? Do you know how the roll resistance is being distributed over the front and rear axis? If you want to stiffen an axis, do you need stiffer springs or a stiffer anti-roll bar? Do you know how to measure the aerodynamic downforce and how this is distributed? What about the Ackermann geometry? etc...

‘Magic Numbers’ is made for engineers in professional and top-amateur racing teams as well for automotive students and Mechanical engineering students, who would like to know their car better, and who would like to be able to improve the performance of the racing car by calculations rather than 'gut feeling'.

During the Workshop ‘Magic Numbers from Race Cars’ the participants will learn how to measure and calculate the most important dimensions (Spring rate, Anti-roll bar spring rate, position of Roll Centres, Motion Ratios and the position of the CofG in 3 dimensions split in the CG from the sprung mass, unsprung mass and total mass).

Based on the results of these calculations very important values like the Roll moment, Roll resistance and Load Transfer will be calculated. These values are key for the balance of the car during cornering. Besides that, basic measurement methods and calculations will be shown to determine the (aerodynamic) CDA and CLA values without visiting an expensive wind tunnel. Also the theory of Ackermann will be explained and a method of determining it on your car will be given. Basic calculations on the shock absorber will be shown, which allows the user to very quickly find the initial shock setting. Finally it is explained what steps could be taken to understand the transient phase in a corner (between steering-in and mid-cornering) with help from your data acquisition system.

The underlaying theories of all values and measurements will be explained in a clear manner, expended with lots of practical examples as experienced by the workshops teacher Ton Serné.

The participant of this workshop will return to the team with lots of very useful calculations and good ideas to prepare the car for next season. Especially the fact that the car will be set up much better initially will save a lot of expensive and time consuming testing at the track!

Please note that only a maximum of 14 participants can be accepted!

BOOK: ‘PRACTICAL COURSE VEHICLE DYNAMICS’

Together with Prof.Dr. Ralph Pütz from Germany Ton Serné published (Aug'17) a German language book titled 'Rennwagentechnik - Praxislehrgang Fahrdynamik'. The English version of this book: 'Racecar technology - Practical Course for Vehicle Dynamics' is expected in spring 2019.

This book has the same basic idea as the workshop Magic Numbers: nowadays 99,99% of the competitors in motor racing use an existing car, be it new or used. But the question is: how well do you know your car? Do you know the roll moment exact in numbers? Do you know how the roll resistance is being distributed over the front and rear axis? If you want to stiffen an axis, do you need stiffer springs or a stiffer anti-roll bar? Do you know how to measure the aerodynamic downforce and how this is distributed? What about the Ackermann geometry? etc...

This book is a very practical, and yet theoretical detailed book which will be actually used in the workshop.

As soon as the English version of this book is available, it will be notified at this site.

About Ton Serné

Ton Serné finished his study Mechanical Engineering with a thesis about ‘Handling of Racecars’. During and after his study he was mechanic in miscellaneous Formula classes, a.o. Formula 1 with the Ensign based Boro team (driver: Gijs van Lennep). Also he raced Formula Ford himself. During the period that he lived in Germany, Ton was team manager of the Bross Formula 3 team, with which team he won the European EFDA cup in 1987.  

Later on he raced various saloon cars like Seat Ibiza and VW Golf GTi. Also he is visiting lecturer ‘Vehicle Dynamics’ at two Dutch universities for Automotive Studies.

Currently Ton is involved in the development of the handling (design of the suspension, geometry, dynamics of the springsystem, laptime simulation etc) of a GT4 project.

Together with Prof.Dr. Ralph Pütz from Germany he published a German language book titled 'Rennwagentechnik - Praxislehrgang Fahrdynamik' in August 2017. In English: 'Racecar Technology - Practical Course for Vehicle Dynamics'.
