MARIN CABRERA, Luis Orlando; GARCIA DE LA FIGAL COSTALES, Armando Eloy  e  MARTINEZ RODRIGUEZ, Arturo. Influence of the Forward Speed in the Cutting Forces of a Vibrating Subsoiler. Rev Cie Téc Agr [online]. 2023, vol.32, n.1  Epub 01-Mar-2023. ISSN 2071-0054.

In the present work, it is analyzed the behavior of the cutting forces (draft force and vertical force)of a vibrating subsoiler tilling a silt loam soil (ferralitic), by a soil-tillage interaction simulation model, developed applying the Finite Element Model and using the elastoplastic Drucker-Prager constitutive model and Solid Works design software. The soil parameters and properties required for simulation, the boundary conditions and acting loads were assigned to model and the meshing of the model was realized. Several running of the model were also realized for four forward speeds (0 ms-1; 0, 4 ms-1; 0, 8 ms-1 and 1, 2 ms-1). The results showed the quadratic behavior of both forces with the increasing of forward speed.
