A Factorial Experiment for Determining Tire Performance Targets of Passenger Cars

Abstract

In the initial stage of vehicle development, tire characteristics that influences vehicle performance such as fuel economy, noise vibration, ride comfort, driving stability and brake performance are considered by car manufacturers. And they are requested to tire manufacturers as performance targets. To determine reasonable performance targets, it is important to estimate the tire characteristics such as mass, rolling resistance, natural frequency, vertical stiffness, cornering power and friction coefficient. In this study, the relationship between the tire characteristics and design factors has been clarified by using the L8 orthogonal array. The present method can estimate the tire characteristics.
