Estudio de los factores que inciden en la baja fiabilidad del elemento de labranza de un motocultor YTO DF-15L.

Abstract

This project is a study on the factors that have an impact on the low reliability of the element of farm work of the YTO DF-15L rototiller. Many tests were applied to the rotary cultivator blades, such us: tests of microstructure, hardness, spectrometry and ultrasound, the blade was designed in SolidWorks software and the efforts that are under the knife to carve the soil were analyzed by a software of finite elements as it is Ansys. These tests characterized the factor of the problem of the low reliability of the element of farm work (rotary cultivator) and the material if which the blades are made was also known. The study of the farm work element was focused to the design geometry due to it is the main factor to have low reliability in the blades of the farm work element, it was also verified that the material does not have influence in the low reliability of the farm work element because the blades are made of AISI 1030 steel which is appropriate for the elaboration of blades to be used in farm work. During the field tests, it was verified that the alternative of reinforce the blade by adding material is the best to solve problem caused because of the low reliability of the farm work element. Based on the results, the problem of the low reliability of the farm work element (rotary cultivator) will be solved and the rototillers that are not in use at MAGAP- Chimborazo province will be working.
