CONSIDERATIONS REGARDING 3D MODELLING AND FINITE ELEMENT ANALYSIS OF A CULTIVATOR TYPE EQUIPMENT

Although it has been neglected in recent years, cultivation is once again finding its place in the field of agricultural crop management. The basic activities carried out by farmers in modern agriculture include plowing, opening the top layer of the soil and mechanical removal of weeds. Tools such as harrows or cultivators are used for these activities. This work presents in the first phase the modeling of a cultivator that can be mounted on an agricultural tractor with a power of up to 20 kW. The 3D model of the cultivator was analyzed in a second phase using a specialized software, Autodesk Inventor Professional 2020. The finite element analysis aimed at highlighting the behavior of the cultivator type equipment during the work process, a very important aspect for the specialists in domain who must permanently ensure that the operation of these machines is carried out at optimal parameters. Following the analysis, the results chosen for visualization were the stresses and deformations of the cultivator's work equipment, as well as the displacements of the structure nodes.
