Abstract

In recent years, increasing attention has been paid to rolling resistance in pneumatic tyres which influences fuel economy. Road texture is well known to have a significant effect on noise emission due to tyre/road interaction. However, studies on rolling resistance mainly focus on tyre design instead of the influence of road properties. This work aims at predicting the influence of road texture on both rolling resistance and tyre/road noise.A numerical model is designed in two subsequent steps. The basis of both steps is a finite element description of a tyre. First, the energy dissipation in the steady state deformed tyre is modeled using the ‘Steady State Transport’ algorithm in the software package Abaqus. This step determines the steady state rolling resistance due to the continuous deformation of the tyre in case of a perfectly smooth road surface. Second, a modal description of the deformed tyre is extracted and a frequency dependent damping and tyre/road contact model are introduced. Measured road texture profiles are used as an input to study the influence of road texture on rolling resistance and tyre/road noise.To verify the numerical results, measurement trailers are used to determine the rolling resistance and tyre/road noise on 40 test tracks with different texture properties. Road texture profiles are measured using a stationary laser profile meter. Regression analysis shows that a clear correlation exists between rolling resistance and road texture. The measurement data indeed shows a constant ‘Steady State’ part and a ‘Texture Induced’ part of the rolling resistance which justifies the modeling approach.
