Analysis of the energy consumption of a rotary harrow

This paper describes the development and study of a finite element numerical model (FEM) rotary harrow. A proper use harrow depends on its geometry operating parameters, such as drag speed angular speed. The aim this work is to develop in ANSYS environment order analyse optimize geometric parameters. After validating through comparison with some experimental data, it was used forces exchanged between tines soil function speed, working depth. Different tine orientations three different types terrain were considered.
