Abstract: |
Nowadays, it is important to preserve the moisture
content of the soil which can be executed with
cultivator tools. The objective of this study was the investigation of the
energetic and working quality characteristics of sweep tools by soil bin
experiments conducted in laboratory conditions and the simultaneous
development of a discrete element model (DEM) validated by comparing the
measured and the simulated values of draught forces. Three sweeps were
analyzed differing in aspects of shape and size; the tool widths were 100,
230 and 300 mm, respectively. Experiments were conducted in the NARIC
Institute of Agricultural Engineering soil bin facility filled with sandy
soil with volumetric moisture content of 2% and 15%, at three different
working speeds (0.5, 1, 2 m/s) at the working depth of 0.15 m. The improved
DEM model contain a soil model consisting of discrete particles created
within the Yade software and 3D laser scanned model of the sweep tools.
Inserting the analyzed tool geometry into the simulation made it possible to
investigate the characteristics of the tillage tools and also the effect of
the different geometries appearing in the soil cutting forces. The
investigation of the effect of the shape of the particles on the energy
dissipation and studying the differences between the validated frictional and
the cohesive soil models based on the soil bin test were the aim within this
study. |
