Abstract:
The world saw a jump in farm energy last year. More than half of energy consumed in agriculture is used for tillage operations. The correct identification of the factors affecting tillage and soil moisture determines optimal conditions for the working conditions of tillage plants. The design and construction of appropriate tillage implements requires sufficient knowledge of the interaction between soil and tools. In this research, the interaction between soil tillage and soil tillage systems was investigated experimentally in a laboratory scale. Also, using Abaqus finite element (ABAQUS, 2010), the force input on a tillage machine that moves at a speed of 1m / s at a depth of 7cm is calculated, The simulation results were compared by finite element method with the results obtained from the experimental method. In order to conduct experiments, a soil bin with appropriate soil texture and grains was used and applied in two levels of moisture of 10 and 15%. The blade motion was carried out perpendicular to the soil in three depths (20, 10 and 30). The results of the experiment showed that there was an acceptable agreement between observational data and modeling data. By increasing the depth of work and also by increasing the moisture content, the force required for the blade displacement increased and the tensile strength increased significantly.
