ABSTRACT
Over the years, the finite element method (FEM) has been successfully used as a virtual test bench by tyre developers and researchers to study the performance of different tyre builds for a wide variety of operating conditions. This approach offers a cost effective alternative to expensive measured tyre behaviour data. However, most of the reported work on FE tyre model tends to focus on passenger car, truck and aircraft tyres. Currently, there is a dearth of published FE studies on motor sport tyres such as those used on formula student (FS) cars. As a major step towards conducting FE studies on FS tyres, an image processing technique, which provides a feasible and adaptable approach for FE tyre cross-section modelling is proposed. The tyre geometric data created is used to create an FE tyre model using a commercial FE code ABAQUS®. The model created using this approach is found to give reasonable prediction of tyre performance in static tests.
