Special Offering for 2005 FSAE Students!

Tires and Handling for Racing and High Performance Vehicles
Taught by Paul Haney, acclaimed tire expert and author of The Racing & High Performance Tire

Monday, May 23, 2005; 8:30 a.m. to 4:30 p.m.
SAE Automotive Headquarters
755 W. Big Beaver Road, Top of Troy Building, 16th Floor, Troy, MI

Fees: $195, Students; $495, SAE Mbrs; $595, Non-Mbrs

Overview
The pneumatic tire is extremely complex and not well understood. Automotive and race engineers are forced to rely on experience as well as trial and error methods when trying to get the most from their vehicles.

Capitalizing on the instructor's 20-year struggle to understand how tires work on a car, this seminar provides a practical applied approach to understanding how a car gets around a corner, rubber friction, tire behavior, and basic vehicle dynamics. While the information presented explains tire technology and vehicle dynamincs in general, the seminar uses racing and high performance settings to illustrate the major points.

Benefits of Attending
By attending this seminar, you will be able to:
· Explain how a tire develops a slip angle and develops a lateral force enabling a car to turn a corner with speed and control.
· Describe rubber friction and rubber's sensitivity to temperature, sliding speed, surface texture, and vertical loading.
· Illustrate how tires and vehicle dynamics influence car's balance and control.
· Summarize the importance of inflation pressure and how to use temperature measurements to find the best pressure.
· Judge how to choose basic starting spring and anti-roll bar rates and develop them toward an optimum setup.

Who Should Attend
Anyone involved with racing and high performance driving as well as engineers involved with tire design, tire testing, or chassis/suspension development. While no technical background is required, attendees are encouraged to have a basic understanding of high-school-level math and physics.

Seminar Content
· How a Car Turns a Corner
· How a tire generates lateral force with slip angle
· How lateral force and slip angle allow a vehicle to turn a corner with control at high speed

· Rubber & Rubber Friction
· Brief history of rubber and its unique characteristics
· Complexity of how rubber interacts with a surface to produce friction forces
· Rubber's sensitivity to temperature, sliding speed, surface texture, and vertical loading
· The real reason there's more grip off-line in the rain

· Rubber Compounding
· Rubber choices; the complex nature of tires starts with rubber.
· How carbon loading and the vulcanization process modify rubber characteristics

· Tire Design and Manufacture
· How tires can be flexible but strong while describing some design goals and structural variables
· Why inflation pressure is so critically important to tire performance and reliability
· How a tire generates heat as it rolls

· Tire Behavior
· How a tire produces lateral force and turns a car
· Importance of camber thrust, induced drag, aligning torque, the friction circle, and load sensitivity
· The real reason wide tires produce more grip
· Why tires are load sensitive and how that affects suspension trade-offs

· Balance and Control
· Understeer and oversteer
· How good drivers maintain control at the limit of adhesion

· Race Tires
· How to take tire temperatures
· Scrubbing, blistering, and graining
· How to find the right inflation pressure
· Typical data provided by tire manufacturers to race teams"”how useful is this data?

· Basic Vehicle Dynamics
· Physics of a car in a corner
· Lateral and longitudinal weight transfer
· Suspension antis
· Importance of roll centers and how to calculate the different components of lateral weight transfer.

· Tuning for Grip and Balance
· How to tune a racecar one level at a time
· Difference between spring rate, wheel rate, and tire rate
· How to choose initial spring rates, anti-roll bar rates, and roll center locations
· Geometric stiffness and why it is so important
· Importance of wedge and how both anti-roll bars and dampers produce wedge effects that help balance a car and generate grip
· Sequence of tuning changes and how those changes affect tire contact patch forces
· Why a front anti-roll bar is so useful

About the Instructor
Paul Haney attended drag races and sports car races in Texas in the 1950s. This began an intense interest in motor racing that led to an engineering degree followed by several decades in the aerospace, materials, and electronics industries.

During the 1980s Paul became involved in racing, working for several racing businesses and writing for motorsports publications. Paul has published three books and now offers a web site, www.insideracingtechnology.com (http://www.insideracingtechnology.com). Paul's latest book, The Racing & High-Performance Tire, co-published with SAE in April 2003 is the result of 20 years trying to figure out how tires work and how a car uses them to get around a corner.

Paul now works with race teams and presents seminars on tires and racecar tuning that explain how tires work on a car and how to approach chassis setup with the goal of optimizing tire usage for traction and driver control.

A member of the planning committee of the SAE Motorsports Engineering Conference and Exhibition, Paul chaired the MSEC vehicle committee in 1998. He holds a B.S. in mechanical engineering from Southern Methodist University.

Just a reminder, registration is underway for this event and if you want a guaranteed spot register soon. It's only one more day in Michigan and if you want a jump start to 2006 this is a great way to do it. Mr. Haney is a design judge as well, if you leave Detroit without attending this or the Rouelle seminar you are missing out.

Does anyone know whether the seminar will go above and beyond what's in the Haney tire book?

Having the author present the material will probably still teach something to those familiar with the book... but I'm just wondering if there's anything particularly new being presented. Anyone know?

Cheers,
Nick

I have only seen an abbreviated version of this seminar, however it did include more than was just in the text. I've been told that the book was finalized about 3 years ago and there is quite a bit of new material that isn't in the text. Mostly more in-depth discussion of book subjects but also some new material.
