EN Elastomer materials are commonly used in manufacture of parts of machines and vehicles. A numerical analysis of these elements is possible with many calculation methods, however, due to such properties as incompressibility, very often large deformations, non-linear constitutive compounds, friction and contact phenomena, an analysis by the fmite element method turns out to be a very complicated task. The purpose of experimental studies which were carried out was to determine parameters of hyperelastic materials used for production of elastomer tracks for industrial vehicles. Experiments were carried out with rubber test samples of the hardness close to the hardness of materials used for manufacture of rubber tracks, lining of the driving wheels and track rollers. These parameters were determined for models of hyperelastic materials (Mooney-Rivlin) used for calculations. The obtained results were comparedby numer ical calculations with the help of the finite element method with a model sample at identical load conditions for various models of a material including a material of linear properties (of the constant Young's modulus). Obtained results of studies and numerical analyses demonstrate only a limited potential of the use of linear models for hyperelastic materials - this use is possible only at small deformations. Obtained results of measurements and analyses can be used for proper modelling of parts made of elastomer materials.
