Mathematical Models for Tillage Implement Draught

A Review

Abstract

A review was conducted on mathematical models for the prediction of draught for soil cutting implements taking into consideration that, soil characteristics differ from one location to the other. The importance of draught force prediction models for tillage tools was studied. The work reviewed the most common types of models used in the prediction of draught for tillage tools on different soils. Similarly, the study shows some of the different techniques used in the development of tillage implement draught prediction models which includes; the finite element method (FEM), fuzzy inference system (FIS), Artificial Neutral Network and Dimensional Analysis using Buckingham pi Theorem etc.). It was recommended that, draught prediction model for different tillage implements can be developed depending on the soil type. This will guide the implement manufacturers and farm managers in proper designing or the selection of implement for a particular region.
