MARIN-CABRERA, Luis Orlando; GARCIA DE LA FIGAL-COSTALES, Armando Eloy  y  MARTINEZ-RODRIGUEZ, Arturo. Rake Angle Influence of the Vibrating Subsoiler Arm in Cutting Forces and Soil Failure. Rev Cie Téc Agr [online]. 2025, vol.34  Epub 01-Ene-2025. ISSN 2071-0054.

In the present work is analyzed the rake angle influence of the vibrating subsoiler arm in the cuttings forces, as well as the soil failure behavior, tilling a silt loam soil (ferralitic), by a soil-tillage tool interaction simulation model, developed applying the Finite Element Model and using the linear elastoplastic Drucker-Prager constitutive model. For modeling was used the Solid Works design software. It was assigned to model the parameters and properties of soil required for simulation, the boundary conditions and acting loads were applied as well as the meshing of the model. As well, several running of the model was realized for three rake angle (15°, 25° y 35°). The results showed the quadratic behavior of draft force with the increasing of subsoiler arm rake angle.
