Finite element analysis of soil forces on two tillage tools



Finite element analysis of soil forces on two tillage tools



Canadian Agricultural Engineering 33(1): 39-46



Three dimensional finite element analysis was carried out to simulate soil cutting with rectangular flat and triangular tillage blades at different rake angles. Interface elements were used to model the adhesion and the friction between soil and blade surface. The soil forces obtained from finite element analysis were verified with the results from laboratory tillage tests in a soil bin. It was shown that the finite element model predicted draft force accurately for both tillage tools.
