Dynamics Understanding Parameters Influencing Tire Modeling Nicholas D. Smith Colorado State University, 2004 Formula SAE Platform Copyright © 2003 Department of Mechanical Engineering, Colorado State University ABSTRACT TIRE BACKROUND The purpose of this document is to describe important While the wheel may have been one of man’s first tire characteristics and their effect on vehicle inventions, the rubber tire is definitely not one of the performance. Characteristics considered are those that simplest components to analyze. The rubber tire is a the Formula SAE judges have deemed important for complex composite consisting mainly of vulcanized discussion on tires at competition and include coefficient rubber, which more specifically is an elastomer with a of friction, slip angle, slip ratio, camber angle, cornering high number of sulfur cross-links between the polymer stiffness, camber stiffness, self-aligning torque, normal chains. The composite also contains carbon black, oil load sensitivity, load transfer sensitivity and pneumatic extenders and layered reinforcing strands or fabrics trail. Every effort has been made to list sample values to called plies. These strand
