46th Tire Mechanics Short Course

To be held concurrently with the expo on 19 - 22 February 2018.

This four-day educational and developmental course will provide engineers and scientists with an in-depth, intense study of the latest developments surrounding tire engineering. The course is designed for practicing engineers, chemists and scientists who are concerned with tires and vehicles and 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 prepared by the instructors will be provided for all participants. Those who complete this course will receive a certificate from the University of Akron.

9:00 - 9:30

Welcome and introduction

Dr Benjamin T F Chung
Department of Mechanical Engineering
The University of Akron, Akron, Ohio, USA

9:30 - 15:30 (Complimentary lunch 12:00 - 13:00)

The tire as a vehicle component

Dr Gerald Potts
DGRP Consulting
Akron, Ohio, USA

Today’s pneumatic tire must serve four functions: to support a moving load; to generate steering forces; to generate driving and braking forces; and to 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, which must be tough and strong, yet flexible.

  1. Basic functions
  2. Lateral force tire models
  3. Cornering transients
  4. Vehicle ride characteristics

15:30 - 17:30

Tire materials and manufacturing

Dr Joseph Walter
Department of Mechanical Engineering
The University of Akron, Akron, Ohio, USA

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 vulcanisation prior to final inspection.

  1. Tire construction and materials
  2. Tire polymers and rubber compounds
  3. Textile and steel cord reinforcement
  4. Tire manufacturing
    1. Rubber compound operations
    2. Tire component operations

Tire materials and manufacturing (continued)

Complimentary lunch

13:00 - 18:00

Impact of rubber and reinforcement properties on tire footprint mechanics

Dr Mahmoud Assaad
Global Tire Performance Prediction, Computational Mechanics
The Goodyear Tire & Rubber Co, Akron, Ohio, USA

The viscoelastic behaviour 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’ behaviour 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. Cornering transients
  4. Footprint mechanics and tire forces and moments

9:00 - 15:00 (Complimentary lunch 12:00 - 13:00)

Tire stress and deformation analysis

Dr Michael Trinko
Technical Center
The Goodyear Tire and Rubber Co, Akron, Ohio, USA (Retired)

The properties of the anisotropic cord rubber composite have primary control of the overall performance characteristics of pneumatic tires. To optimise 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 properties calculation
  2. Analytical techniques (classical methods)
    1. Equilibrium tire design
    2. Cord loads, belt loads, sidewall loads
    3. Air diffusion calculation
    4. Beads load, bead contact forces
  3. Footprint contact behaviour
  4. Cord loads for traction, cornering
