Determination of Basic Mechanical Parameters of the Tractor Tyre by Using Universal Approach
Journal Title: Machine Design - Year 2017, Vol 9, Issue 1
Abstract
Tyre behaviour exerts crucial impact on every aspect of vehicle dynamics response. It is therefore of interest to have access to appropriate tyre model in order to address vehicle behaviour optimization by means of computer simulations. In this paper procedures for determination of some basic parameters of tractor tyre by using simple test facility and universal measuring techniques are described, including dependence between tyre vertical load, static radial deflection and contact length on the hard level ground, linearized radial stiffness and damping coefficients. Impact of tire pressure and vertical load on investigated quantities and relationships is also examined. Set of tyre parameters that can be used in simple tyre model was obtained. Linearized stiffness and damping coefficient values can be used in certain applications of tyre viscoelastic structure modelling. Relationships between tyre load, deflection and contact length can be useful when investigating tyre geometric or filtering properties such as enveloping behaviour.
