Estimating stresses and movement work of a soil-cultivator tip using the finite-element method

Abstract

Working parts of tillage machines are in direct contact with soil abrasives. The shape and dimensions of the working parts undergo changes due to friction and wear. A finite-element model has been created for studying the stresses and in-soil movement work of the designed cultivator tip. The problem has been solved with a coupled Eulerian–Lagrangian method (the SIMULIA ABAQUS software). It has been shown that the minimum in-soil movement work of 3400 J is done by a tip with a sharpening angle of 185°.
