FEM model for the study of agricultural soil compaction under the action of two-wheel tractor

  • 1 Univers ity “Politehnica” of Bucharest, Romania


This paper presents a theoretical model that allows estimating the state of tension in agricultural soil under the action of the wheels of a cultivator (two-wheel tractor), using the finite element method. Improper operation of cultivators and their improper use can lead to the degradation of agricultural soil by generating excessive mechanical stresses that favor the occurrence of artificial soil compaction. The finite element analysis models developed in this paper allow a dramatic reduction in the costs of experimental testing as well as the time required to estimate the possibility of artificial compaction of agricultural soil under the action of cultivators.
