In this paper the soil-rigid wheel interaction was analyzed using Discrete Element Method (DEM). Three types of soil model were created with different mechanical properties. After that, the rigid wheel was simulated in two different ways: in the first case it was created as a rigid wall and then as a rigid particle. In each calculation the sinkage of the wheel was measured under different vertical loads. After that, the results of the simulations were compared to the theoretical values. To determine the theoretical sinkage values the Bekker-formula was used. Finally the accuracy and the calculation times of the two simulation methods were compared to each other.
