THE COMPUTER MODELING OF INTERACTION BETWEEN SHARE-MOULBOARD
SURFACE OF PLOUGH AND SOIL
Summary
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.
Key words: plough, share, mouldboard, soil, interaction, computer modeling
