Vehicle Dynamics & Data Acquisition Seminar

For three days in December, Claude Rouelle of OptimumG brings his highly acclaimed tutorial covering all aspects of data acquisition and vehicle performance to Indianapolis, where it will join the Performance Racing Industry Trade Show for its return to the Racing Capital of the World.

December 9-11, 2013
Indiana Convention Center
Room 244

Esteemed race engineer Claude Rouelle from OptimumG will once again offer in-depth instruction on vehicle behavior, including measurement tools, aerodynamics, ties, weight transfer, tuning and more during a three-day event at the 2013 PRI Trade Show.

Sessions for the Vehicle Dynamics & Data Acquisition Seminar, scheduled for 8 a.m. to 5 p.m., December 9-11, in Room 244 of the Indiana Convention Center in Indianapolis, will cover every aspect of vehicle dynamics, and wrap up with data acquisition and analysis.

“Our composite audience includes amateurs, students, aerodynamics, data acquisition, tire people, etc.,” said Rouelle. “Our attendees learn not only from me, but from each other. It’s not just about science, but about perspective.”

Indeed, the seminar is designed for multiple skill levels, whether you’re a seasoned veteran in the field of vehicle dynamics, just starting out, or anywhere in between. It’s intended to push participants beyond experience and intuition, and allows them to interact with each other, watch live demonstrations, and ask questions to get collaborative feedback.

“It’s highly informative and extremely in-depth,” said Kevin VanCleave, owner of KSV Inc. and formerly a technician at RSR Motorsports who attended the 2012 seminar at PRI. “Claude’s developed a seminar based on developing a methodology to work with your race car instead of a recipe. Everything is interconnected—if you have one thing go wrong, everything falls apart. With Claude’s system, the more you learn, the more questions you have. It’s connecting dots and then creating new openings. It’s worth every penny.”

Topics to be covered include:

Tires: The only elements of your race car in contact with the ground, understand why and how much the grip, balance and performance of a car is decided by the contact patch forces and deflections. We will also cover tire testing, analysis and how to use tire data in race car design and setup.

Aerodynamics: After a review of aerodynamics basics, we’ll focus on the understanding of aero-maps, wings, gurney flaps, static and dynamic ride height settings, and how to integrate them into the design of a suspension.

Kinematics: See why poorly designed kinematics cannot be “patched” by springs, antiroll bars and shocks. And why, from the design to on-track testing and racing, understanding the effects of kinematics is essential to the efficient use of race tires. We’ll also explain the essential differences between kinematic and force roll centers, as well as kinematic and force pitch centers.

Steady State Weight Transfer: Understand, step-by-step, the weight transfer calculation in steady state. See the influence of springs and anti-roll bars on weight transfer distribution, as well as the influence of tire vertical stiffness and chassis torsional stiffness. You will get a guided exercise on weight transfer calculations under combined lateral and longitudinal accelerations.

Shocks, Ride & Transient Weight Transfers: After a brief description of damper technology, we will focus on the damper settings’ influence on tire load, tire load consistency and race car performance. A guided exercise related to spring and damping calculations, as well as selection and fine-tuning of these suspension elements will help you to considerably diminish the amount of time spent in testing and improve your understanding of simple simulation tools.

Data Acquisition: Hear both technical and practical aspects of data acquisition used to develop race car and race driver performance. This knowledge will help you to appreciate the challenges and the satisfactions you face with data acquisition system understanding, choice, installation and calibration, as well as efficient data analysis. We will focus on mathematical data analysis and its direct application to race driver performance, and race car tire performance and endurance evaluation.

Car Design, Tuning Modification And Chassis Setup: Young and experienced race car engineers alike have gotten new ideas, new engineering principles and new perspectives related to car design and testing due to this seminar. You will receive practical information and perspectives on in-shop and on-track car setup. Our “tips and tricks” focus on engineering and constitute a practical application of vehicle dynamics knowledge.
