43nd Tire Mechanics Short Course

Deutsche Messe, Hanover, Germany
February 15–18, 2016

The 43rd Tire Mechanics Short Course will be held concurrently with Tire Technology Expo 2016 Hanover, Germany, February 15–18, 2016.

This four-day educational and developmental course will provide engineers and scientists with an in-depth, intense study of developments surrounding tire engineering. The course is designed for practicing engineers, chemists and scientists concerned with tires and vehicles, and those who have an engineering or science background at the Bachelor of Science level. The basic and practical aspects of the mechanics of pneumatic tires will be introduced by internationally renowned experts in tire mechanics. Over 1,000 pages of course notes on a CD prepared by the instructors will be provided for all course participants. Those who complete this course will receive a certificate from the University of Akron.

Program Schedule

9:00–9:30
WELCOME and INTRODUCTION

Dr. Benjamin T.F. Chung
Department of Mechanical Engineering
The University of Akron, U.S.A.

9:30–15:30 (Lunch 12:00–13:00)
TIRE MATERIALS AND MANUFACTURING

Dr. Joseph Walter
Department of Mechanical Engineering
The University of Akron, U.S.A.

The materials used in today’s pneumatic tires are designed to act in concert with construction features to provide optimum durability and balanced performance for the expected service conditions. The proper combination of compound formulations and structural reinforcements is crucial for successful tire operation. These materials and constructions must then be processed efficiently within the tire factory beginning with mixing, continuing with extrusion, calendering, and component assembly, and ending with vulcanization prior to final inspection.

  1. Tire Constructions and Materials
  2. Tire Polymers and Rubber Compounds
  3. Textile and Steel Cord Reinforcements
  4. Tire Manufacturing Operations
    1. Rubber compound operations
    2. Tire component opeerations

15:30–17:30
THE TIRE AS A VEHICLE COMPONENT

Dr. Gerald Potts
TMSI LLC (MESNAC Company), U.S.A.

Today’s pneumatic tire must serve four functions: (1) support a moving load; (2) generate steering forces; (3) generate driving and braking forces; and (4) provide isolation from road irregularities. In examining the complex mechanism involved in satisfying the four requirements participants will study the tire¹s importance in determining overall vehicle performance; for no matter what level of complexity is designed into a vehicle, it's only communication with the road is through its tires, which must be tough and strong, yet flexible.

  1. Basic Functions
  2. Lateral Force Tire Models
  3. Cornering Transients
  4. Vehicle Ride Characteristics

9:00–12:00
THE TIRE AS A VEHICLE COMPONENT (continued)

Dr. Gerald Potts
TMSI LLC (MESNAC Company), U.S.A.

12:00–13:00
Lunch

13:00–18:00
IMPACT OF RUBBER AND REINFORCEMENT PROPERTIES ON THE FOOTPRINT MECHANICS

Dr. Mahmoud Assaad
Global Tire Performance Prediction, Computational Mechanics
The Gooyear Tire & Rubber Co., Akron, OH, USA

The viscoelastic behavior of the rubber compounds and the reinforcing cords influences the stability of the tire footprint shape. Additional physical properties such as the strain dependency of both constituents and their thermal stability contribute to the contact pressure distribution. The resultant tire forces and moments transmitted to the vehicle are measured using tri-axial force pin transducers or pressure sensitive mats. The interaction between the materials behavior and the tire global response control the mechanics of tire abradibility and wear characteristics. The following topics will be discussed:

  1. Rubber viscoelasticity, Static, Dynamic, and Fracture Properties
  2. Fibers and Cords: load-displacement, creep, stress relaxation, and shrinkage
  3. Footprint Mechanics and Tire Forces and Moments

Wednesday, February 17, 2016

9:00–15:30 (Lunch 12:00–13:00)
