| Research Abstract |
Tillage is one of important operations to improve and maintain crop soil condition in farmland. Developments of numerical analysis method have been tried to clarify the mechanism for soil-tillageinteraction phenomena and to reduce the developing time and costs in the present. In this study, the soil tillage simulator was developed based on a three-dimensional discrete element method. Soil resistances acting on plow surface and soil cutting phenomena were estimated in the simulation. The simulated results agreed qualitatively with the test results.
