Diseño y construcción de una máquina de desgaste acelerado para aperos de labranza agrícola mediante Ensayo SAT para el laboratorio de maquinaria agrícola de la carrera de Ingeniería Automotriz.

Abstract

Design and build an accelerated wear machine for agricultural implements by means of SAT test for the agricultural machinery laboratory of the automotive engineering study, to experimentally determine the wear and tear produce on the rotor discs or on the rotavator blades, in order to determine the type of soil that produces the most abrasive wear to these tillage tools, in order to guarantee the quality of the material that is used for the manufacture of these implements. The methodology applied in this technological proposal is supported by the mathematical calculation and use of software for the design considering parameters established as: power, speed, humidity, and soil type, as well as the appropriate selection of alternatives for the construction of the machine. The abrasion test is to cause wear by varying the speed of rotation of an axis, in the same dovetail discs and rotavator blades, also vary the soil types, to deduce which soil causes the greatest wear on these agricultural tillage tools, in the same way, the type of soil will be modified, which will be measured with a hygrometer to simulate different climatic conditions. The results obtained are presented in phases so in the design phase the machine plans, the selection of the materials for its construction, and the functional tests were developed. It was arrived with satisfaction to obtain a real design in the software Solidworks, the software Ansys was of vital importance to determine the factor of security. When handling the machine, wear personal protective equipment consisting of a helmet, gloves, goggles, mask and apron before and during the tests to be performed.
