Abstract

ABSTRACT: The use of finite element (FE) modelling in tyre design and development has now become a popular practice within the tyre industry. Such an approach has helped in enhancing rapid tyre virtual prototyping, hence reducing the cost associated with extensive tyre experimental procedures and shortening the tyre design cycle. Recently, FE models have been developed to simulate steady state tyre rolling condition. However, such models are incapable of solving the challenging problem of tyre transient behaviour, a precursor to a steady state rolling condition, arising from such events as a cornering manoeuvre or a tyre enveloping an obstacle e.g. cleat. This paper addresses the simulation of tyre transient and steady state behaviour during cornering, using a commercial FE code ABAQUS(r). The impact of preload on tyre transient behaviour in terms of the relaxation length is assessed and compared with theoretical experimental results. The model showed comparable results with experimental measurements.
