Abstract
This research paper is devoted to the description of a finite element model for the numerical study of a radial tyre under steady state rolling condition. The finite element model was developed using the commercial computer software ABAQUS. The simulation started with an axisymmetric model to analyse the tyre under inflation pressure load. Then a full three-dimensional model was generated for the modelling of the tyre under static vertical load. Having obtained the tyre configuration under contact load, a steady state rolling analysis was conducted using a mixed Lagrangian/Eulerian technique. In this stage, a constant ground velocity was assumed and the spinning velocity was changed to find the free rolling speed of the tyre. The computed loaded dimensions of the tyre in both static and dynamic situations were also compared with experimentally measured data for three commercial tyres available on the market. The comparison verified the validity and applicability of the proposed model. In addition, the distributions of pressure and frictional shear stress fields at the contact zone are presented and discussed.
