| The way of modeling the contact phenomena of two bodies - with a finite and infinite radius of curvature - is presented in the paper. The basic method used in the research was the finite element method. A model to simulate deformations occurring during rotational and translational movement of a wheel on a flat surface was developed. The research was based on the own design solution of the mobile platform's running gear. The model takes into account all geometrical parameters, the flexibility of the contact zone loaded, and orthotropic material properties of the analyzed meso-structural bodies. The work contains the values of all parameters of the material model that were obtained experimentally. The final result of the study was to determine the relationship between rolling resistance and external loads. |
