Analysis of the energy consumption of a rotary harrow



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