The paper presents a full three-dimensional finite element model of pneumatic tyre. The inclusion of a special node to the model enabled to analyse the problem of static tyre-road contact under vertical, lateral or longitudinal external forces. The hyperelastic properties of rubber are described with the use of the elastic strain energy density function in the form of the third degree polynomial. Incompressibility is taken into account by means of the Lagrange multiplier-in the form of mean hydrostatic pressure determined within each finite element. Particular attention was paid to the directional properties of cord ply treated as monotropic linear-elastic material characterized by effective material constants. These properties were introduced into the model by overlaying the elements with monotropic material on those representing rubber. The total Lagrangian description with the Green-Lagrange strain tensor and the energetically conjugate to it the second Piola-Kirchhoff stress tensor were applied to the tyre model. The results of a truck tyre analysis concerning displacements and delamination stresses distribution show good accuracy of the pneumatic tyre modelling technique proposed in the paper.

The aim of the paper is to propose and verify an effective method for the realistic modelling of pneumatic tyres. A static, three-dimensional model of a pneumatic tyre, based on the finite element (FE) program MARC, is presented. The cord-rubber composite was modelled by overlaying the elements characterizing the cord and those representing incompressible rubber. A two-dimensional model was used to simulate the tyre mounting and inflation process. The model was then developed into a three-dimensional one. The displacements, radial stiffness and delamination stresses caused by the vertical load were determined. The shape of the tyre footprint and the pressure distribution in this zone were also predicted. Good correlation between measured and computed stiffness characteristics was observed. The proposed technique of element overlaying yields a tyre model that is numerically more stable than that using only orthotropic elements (very stiff cord merged with compliant rubber).

“…The study is not limited to the low frequency range, typical of vehicle dynamics oriented tyre studies, as the demanded representation accuracy of contact deformation necessitates a frequency range much broader than the one typically examined in vehicle dynamics studies [1]. The aim is to identify the effect of different modelling techniques on a tyre model derived by a modal expansion and reduction process.…”
