Researches on the use of finite element method to optimize the wheel tyres exploitation for agricultural vehicles

Abstract

This paper presents an analytical model using finite elements method, allowing the study of the interaction between agricultural tractor tyres and the rolling track, the distribution of stresses and strains in different types of rolling tracks (agricultural land, agricultural exploitation land and public land), and in tyres, for various inflation pressure values. A 3D model of the real tyre has been achieved, for which were defined the parameters characterising the elastic behaviour of rubber tyre. Results and conclusions obtained from this study are useful in the identification of optimal operating parameters for tyres driving wheels of agricultural vehicles.
