Abstract
Select the best option of material using the Multi-criterion methodology (MCDM), obtaining the best results and the respective choice of material, achieving a safety factor that protects against faults by bending fatigue and is within the permitted parameters applied to a gearbox of the Dmax 3,0. For which multicriteria decision-making methods were carried out to obtain an order or ranking of the set of alternatives. To obtain this ranking, the set of alternatives must be well defined, just as the criteria must be well determined. After using the multi-criteria, it was determined that the best material option according to the ranking is the AISI 4140, which has relevant characteristics such as elastic limit, tensile strength and good thermal capacity. The methodology used for the weights helps to avoid the designer's subjectivity and make it conform to real parameters. Based on the numerical results, it can be concluded that the proposed methods can deal with the problems of material selection with the dependence of criteria.
