The computer modeling of interaction between share-moulboard surface of plough and soil

Ovsyanko V., Petrovsky A.

Journal of Research and Applications in Agricultural Engineering

2014

Vol. 59, nr 1

100--103

This article presents material parameters for models used to represent soil in LS-DYNA package to numerically simulate interaction between soil and elementary working body – double-face wedges. Comparison of simulation results with the known data of natural tests is given. The modeling of interaction between soil and a share-moulboard surface of plough with the LS-DYNA software by Lagrange’s method is considered.

Computer modeling of beet harvester digging. Bodies-soil interaction

Ivanetz G., Ovsyanko V., Vyrski A., Pigenko V. A.

Journal of Research and Applications in Agricultural Engineering

2007

Vol. 52, nr 1

8-12

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.
