42nd Tire Mechanics Short Course

Koelnmesse, Cologne, Germany
February 9–12, 2015

The 42nd Tire Mechanics Short Course will be held concurrently with Tire Technology Expo 2015 Cologne, Germany, February 09–12, 2015.

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

Monday, February 09, 2015

9:00–9:30
WELCOME and INTRODUCTION

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

9:30–14:30 (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 and calendaring, and ending with vulcanization.

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

14:30–16:00
RULES AND REGULATIONS GOVERNING TIRES

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

Government regulations, industry standards, customer specifications, and marketing requirements directly impact the ultimate design (and consequently the performance level) of all tires especially original equipment and aftermarket passenger car tires. Discussed in this part of the course are:

  1. The current state of regulatory affairs in the US, Europe and Japan governing tire safety and the environment;
  2. The design trade-offs often inherent in meeting sometimes conflicting rules and regulations;
  3. Different markets, different tires?

16:00–18:00
THE TIRE AS A VEHICLE COMPONENT

Dr. Gerald Potts
TMSI, 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, its only communication with the road is through its tires.

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

Tuesday, February 10, 2015

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

Dr. Gerald Potts
TMSI, U.S.A.

12:00–13:00
Lunch

13:00–18:00
DETERMINING TIRE FORCES AND TIRE FOOTPRINT BEHAVIOR FOCUSED ON WEAR

Dr. Marion G. Pottinger
M’gineering LLC., U.S.A.

Tire force and moment development, wear, and traction are largely determined by what occurs in the tire/road contact patch, the tire footprint. This section goes back to how this area of study started in tire force and moment measurement and has evolved into footprint mechanics. The discussion examines the science, aspects of engineering design problems, and limitations of current approaches. A fundamental reference list is supplied along with text incorporated in the Notes Pages view of the slides.

  1. Introduction
  2. Experimental Determinination of Tire Force and Moment
  3. Describing the Tire Footprint
  4. Footprint Study Equipment and Methodologies
  5. Footprint Physics Including Deformation Responses to Individual Operational Conditions
  6. Application to Eliminating Uneven Wear Problems

Wednesday, February 11, 2015

9:00–15:30 (Lunch 12:00–13:00)
ADVANCED TIRE MODELING

TIRE STRESS AND DEFORMATION ANALYSIS

Dr. Michael Trinko
The Goodyear Tire & Rubber Company (Retired)

The properties of the anisotropic cord rubber composite have primary control of the overall performance characteristics of pneumatic tires. In order to optimize a given tire performance, knowledge of the combined cord rubber composite material properties is necessary and will be covered in this part of the course.

  1. Composite Material Stiffness Calculation
  2. Analytical Techniques (Classical Methods)
    1. Equilibrium Tire Design
    2. Cord Loads, Belt Loads, Sidewall Loads
    3. Air Diffusion Calculation
