Finite Element Analysis of a Tire Steady Rolling on the Drum and Comparison with Experiment

Abstract

A finite element (FE) model for analysis of tire rolling on the drum, based on a specially developed CAD model, is presented in the paper. All the changes performed on the geometry of CAD model are automatically propagated to FE model. This makes the FE model very suitable for parametric studies, which help tire designer to quickly find the optimal values of tire design parameters. In this way the tire design process is shortened and the quality of resulting tires improved. The results of finite element analyses conducted on the model have directly been compared to experimental ones, confirming model validity. Equipment and methods used for experimental determination of braking and cornering characteristics of the tire as well as for experimental determination of friction coefficient of tire tread have been shown. The difference between experimental and numerical results was smaller after the calibration of friction coefficient had been performed and in such a way a further improvement of the existing model was achieved.

Finite element analysis of a tire using an equivalent cord model

“…This characteristic cannot be reproduced when beam elements are used to represent cords. In other studies [2,3,6,7,8,10,11,12,[20][21][22][23][24][25], rebar elements were used to represent the cords in belts. However, rebar elements cannot duplicate the bending behavior of cords either because rebar elements are used to define uniaxial reinforcement.…”

“…Modeling the belt behavior is also necessary when studying tire structure [1,5], the interaction between the tire and ground [7][8][9][10][11][12], the temperature distribution in the tire [1,9], and the effect of blast waves [13]. Because the cords and rubber that make up the belt have very different Young's moduli, and because anisotropy occurs due to the angles of the cords, constructing a constitutive equation for the belt is difficult.…”

“…When belts are modeled using finite element analysis (FEA), the physical properties of the rubber and cords are combined to yield the resulting physical behavior of the belts [1,5,9,18,19], the internal cords are modeled using beam elements [13] or using rebar elements [2,3,6,7,8,10,11,12,[20][21][22][23][24][25]. Studies that have modeled belts based on a single physical behavior have defined the behavior using isotropic elasticity [1], hyperelasticity [5], the Halpin-Tsai composite equation [9], or theoretically derived belt constitutive equations [18,19].…”

“…The different in footprint and rolling characteristic became even more significant as the drum diameter get smaller [4]. In the recent years, FE models of the drum testing had been developed.…”
