Energy Consumption Evaluation of Active Tillage Machines Using Dynamic Modelling

Abstract

Soil tillage is a very energy-intensive operation. A general expectation is to reduce energy consumption and reduce soil compaction with as few turns and interventions as possible. Thus, more and more attention is being paid to the use of active tillage machines. The aim of the present work is to test a new approach to optimize PTO-driven tilling machine operations regarding energy consumption. A real, active tillage machine, the MSS-140 type spading machine, was investigated in the Matlab® Simscape™ environment. The solid model of the spading machine was built using actual dimensions. The work done by a single spade is broken down into elementary processes. The acting forces on the implement, in each elementary process for different advancing speeds, were modelled and calculated. The model is suitable for illustrating the dynamics of loads and for calculating the mechanical work. The model was also tested in comparison with real fuel consumption. The consumed fuel quantity was measured and the energy requirement for the model calculated at three advancing speeds. A comparison between the measured and calculated energy consumption values was made: the calculated results are similar to the measured values; the mean difference is 9.91%, with a standard deviation 3.3%.

Study of the Effect of Soil Volumetric Weight on the Energy Requirement for a Spading Machine by Simulation

“…For our study we use a real spading machine model, the MSS-1,40M, and a previously validated SimuLink simulation [8].…”

“…We explore the physical, mechanical properties of the soil that play a role in the spading process. Based on the literature [8], we determine their values for soils that are easy to cultivate, moderately cultivable and difficult to cultivate [8].…”

“…The assembly model was built using Autodesk Inventor software based on the actual dimensions of the MSS-1.40M spading machine [8].…”

“…The paper [23] presents a methodology for mechanism simulation in case of agricultural machines, which may be applied at this mechanism also as seen in Fig. 11.…”

Resistance and Consumption Reduction Mechanism of Bionic Vibration and Verification of Field Subsoiling Experiment

“…Soil compaction is one of the most severe forms of soil degradation caused by traditional tillage practices, and it refers to the decrease in porosity between soil aggregates [1][2][3]. The damage of soil compaction on cultivated land, specifically in the form of stunted crop root growth, affects crop growth [4]; the supply chain of water and nutrients in the soil will be broken [5], with the microbial colony imbalance; the number of host organisms, such as earthworms, will decrease [6].…”
