This diploma thesis deals with the optimization of the geometry of the components of the chisel plough. Optimization is done using discrete element method. The aim of the thesis is to conduct the necessary research to create a virtual model of the soil, on which the chisel plough can be tested and subsequently optimize the geometry of individual components. The Altair EDEM program was used to create a virtual model of the soil. The virtual soil model is based on experimental measurements of soil properties. During optimization, the force effects were recorded directly by the Altair EDEM program. The resulting furrow shape was also monitored during the optimization process. In the end, DEM-MBD co-simulation with optimized geometry is performed.
