Análisis del comportamiento mecánico de engranes rectos de material AISI 1040 y 4140 sometidos a fatiga mediante simulación por elementos finitos

Abstract

This document refers to the analysis of spur gears subjected to fatigue using the methodology of the equations of AISI / AGMA 2001-D04, for which the analytical model is carried out focused on the contact stress and bending stress caused by the load at the one that is being subjected. Using the SolidWorks Toolbox, the geometry of the gear is created by importing in .IGES format to the ANSYS FINITE ELEMENTS ANALYSIS (FEA) software which, thanks to its versatility in terms of handling and the variation of materials, allows a study to be carried out using meshing criteria Quadrilateral and triangular type with a quality of 0.9 and 0.3 respectively, which provided results of the maximum efforts of Von Misses, which in comparison to the results obtained by AGMA shows an average variation of 15%, this value is justified because ANSYS does not take into account the correction factors used by AGMA
