ABSTRACT
The objective of the article is to elaborate the beet harvester digging bodies virtual tests using LS-DYNA package installed on the SKIP k-1000 supercomputer in VHP NAS of Belarus. The process of beet digging out is simulated. For the soil simulation an isotropic material with failure (Mat_FHWA_SOIL) was used. Different types of soil models are obtained by input parameters varying. The calculations were carried out in EXPLICIT and SPH-particles formulations. In the SPH-p article formulation the continuous media is substituted by a set of particles that move with the flux velocity. By means of soil material coefficients and SPH-elements characteristics the viscous media behavior is described. Soil particles displacements during treating were traced.
