A numerical analysis of the influence of working depth on subsoiler stress

Abstract

In order to increase the yield, there are a large number of agricultural machines that can help with this. One of them, which is analyzed in this paper, is a subsoiler. Subsoilers are machines for soil cultivation characterized by a strong ability to spread and crush the soil. The principle of cultivation is to turn and break down the soil to a fine tilth to provide the ideal environment for seeds to germinate. During the soil cultivation, a great traction resistance is present and for this reason, a high-power propulsion machine is required. This results in deformation and stresses occurring on working body. How the change in working deep reflects on the deformations and stress that occur during cultivation are analyzed in this paper. Analysis was performed using the software package ANSYS.
