Finite element modelling of the interaction of the cutting edge of tillage implements with soil

摘要: Finite element modelling was undertaken to study the effect of cutting edge geometry tillage implements and compare results with previously measured forces, soil failure patterns movement below depth. Two-dimensional finite compared tests conducted using 400 mm wide experimental sweeps under controlled conditions a test track (large outside continuous bin) in field. Corresponding were also glass-sided bin help quantify interactions between implements. The showed important role value Poisson's ratio has on action that technique can be used predict various geometries forces around edge.
