| Popis: | For effective tillage, design and selection of tillage tool according to soil type and condition is very important. The present study is carried out for in-depth investigation of different types of shovels of tine cultivator and behavior of soil in response to loads subjected during tillage using finite element analysis. Different types of shovels like reversible, duck foot, seed drill and cultivator shovel are simulated with different types of soil like sand, clay and loam. The origination, level and distribution of stresses and deformations in shovels experienced in different types of soils are probed. Furthermore, high stressed and crack sensitive regions are identified. The stresses of 18, 53, 64 MPa are generated in reversible shovel of tine cultivator during ploughing in sandy, clay and loamy soil respectively. In addition, results of different shovels are compared, and it is found that the duck foot type shovel experiences highest stress and deformation. The duck foot shovel experiences about 20 and 71% higher stresses in loam compared to that in clay and sand respectively. Moreover, the study of soil mechanical behavior shows that the soil block (clay soil) experiences maximum stress of 34 MPa while tilling with reversible shovel. The statistical analysis is also conducted that shows high significance of simulation results. |
