Diseño, fabricación y pruebas de un prototipo de arnés de sujeción y operación, para la desmalezadora utilizada en el sector agrícola en la Empresa “APROCAI” ubicada en la Provincia de Chimborazo Cantón Cumandá mediante la aplicación del software ErgoMet 3.0

Abstract

The current research work addresses desing, manufacturing and testing of a prototype of a holding and operation harness at “APROCAI” company located in Chimborazo province, Cumandá canton, by applying Ergomet 3.0 software aiming to develop the ergonomic study of the influence of loads, determine the consecuences of repetitive movements and evaluate the new desing of the subjection and operation system by means of the application of the software: Solid Works, Ansys, Ergo IBV; the machining of the pieces will be performed by using other software tolos such as: Matter Controls and Netfabb Basic. By using the inductive method to gather essential elements of the observation; and analytical methods in order to reach the depth of the research; thechniques as surveys, direct observation and Check-list were used, by using Ergo IBV software the following results were gathered; the average frequency, the Reba -1 punctuacion and the risk level is “invaluable”; by using the Ansys software, data were registered with a strength of 7.9 Kgf (77.42N) with PLA polymer, having as a result a total deformaion of 4.7 mm in the holding zone of the appilied load, noticing that the total deformation of the harness desing is not affected. With the statistical analysis it was determined that the subjection and operation harness prototype for the mowing truck in the farming area, affects importantly in the reduction of tiredness levels. It is concluded that the evaluation of the technical and ergonomic study of the subjection harness determined the adequacy of the material, not only for reaching the technical parameters of desing but also its low manufacturing cost. It is recommended to have active pauses in the suggested times so that it reduces the exhaust levels of the workers.
