Desenvolvimento e análise por elementos finitos de suporte para ensaio de tração em parafuso

Abstract

The bolts present in the market currently have several variations and purposes that aim to meet the need of all. They are important accessories for engineering and industry, given their exten- sive applicability. Therefore, they should always be the object of study in order to obtain new, or ratifiable, data on the mechanical properties of them. The support designed in this work aims to provide the Federal Institute of Piauí (IFPI) to carry out the tensile test on hexagonal screws, with the capacity to withstand the stresses submerged to the test body without failure. The ge- ometry used was based on other supports already existing in the list of accessories of the testing machine of the IFPI, with the upper part modified to fit the screw with the minimum of clea- rance. Through the finite element simulation environment of the SolidWorks software, it was possible to analyze the tensions obtained in the assumption. In order to obtain accurate data it is necessary to correctly configure the mesh and the boundary conditions in the simulation en- vironment. After the simulation, it was verified that the tensions present are below the flow limit of the material chosen for the support and that also has a high safety coefficient
