Prediction of rolling resistance and steering characteristics using finite element analysis truck tyre model

Abstract

The purpose of this research is to provide insight into the design and development of a finite element analysis (FEA) model of a heavy truck tyre for the purpose of investigating rolling resistance and steering characteristics. Aspects considered include the effects of design parameters (tyre dimensions, construction, materials, and FEA modelling technique) and operating parameters (tyre inflation pressure, vehicle speed, spindle load, and road surface texture). The model was also developed to predict the effects of combined steering and camber angles on cornering forces, aligning and overturning moments. The findings of this investigation show that the multi-layer membrane material can accurately simulate the tyre carcass structure. Validation tests include the static load-deflection test and dynamic cleat-drum excitation test. The experimental data shows that the generated FEA tyre and wheel model qualitatively simulates a real heavy truck radial tyre. Further work is required to allow for accurate quantitative prediction and would vary largely with tyre construction.
