| Abstract | ||
| With the development of computer science, numerical methods such as FEM, DEM and ANN have been used to study the interaction between soil and tillage tools. Finite element method (FEM) one of these approaches that supposed the soil as continuous materials with different behaviour models. Thus, the main objective of this work is to develop a simulation model for predicting soil forces and consequently power requirements affecting on tillage tools as a function of soil, tool and operational conditions parameters using FEM. In order to study the interaction between soil and tool, a three-dimensional model was performed using Abaqus Explicit Software. The soil was molded with linear forms of Drucker-Pager model, while the tool was considered as a rigid body. The effect of soil properties (moisture content and bulk density), tool parameters (width and rake angle) and operational conditions (depth and speed) on the draft and vertical forces were investigated. Triaxial tests were carried out using clay loam soil to determine the shear strength parameters such as soil cohesion and internal friction angle. Results indicated that finite element method allows researchers to optimize tool designs to reduce energy consumption and improve soil handling. The results found that the highest draft force values were recorded with high tillage depths and high tool speeds. In addition to, vertical force increased as tillage depth and tool speed increased. | ||
