Abstract
The energy required for tillage processes accounts for a significant proportion of total energy usage in crop production. Development of more efficient tillage tools is essential to reduce the energy consumption and to increase agricultural production. Accurate modelling of the soil-implement interaction will allow for optimization of implements without performing expensive and time consuming field tests which may only be undertaken at certain times of the year. However, modelling of soil-implement interactions is a complex process due to variability of the soil profile, non-linear behaviour of the soil material and the dynamic effect of the soil flow. An approach that gives a further insight into this future development is the technique of discrete element modelling (DEM). In many tillage processes decreasing the draft and upward vertical forces is often desired. A study performed by Fielke (1994) showed that in comparison with a sharp cutting edge, a blunt cutting edge increases the draft and upward vertical forces by around 80%. In this paper the field results of Fielke (1994) were simulated using 3D discrete element modelling (DEM) techniques. A good correlation was obtained between the simulation and test results.
