Desenvolvimento e análise por elementos finitos de um suporte para ensaio de fadiga para vergalhões

Abstract

The failures analisys are one of the main elements of study in engineering, and its importance extends to the study of several structures, either in constructions or in machine elements, being of great relevance in the mechanics of solids, becoming in the present day, fundamental for the understanding and extension of the useful life of the materials. The present work aims at the study of a support of fatigue test, developing it in order to withstand the various stresses submitted to the proof body, resisting various fatique tests, where it will later be analyzed using the finite element method (MEF) and theories of static failure and fatigue. Through all methods or designed support, it is developed through machining, where its machined geometry clamps or rebar through a wedge system, which applies more resistance to sliding resistance as more force is applied to the rebar, slipping relative to To rebar, where through a mesh refinement in the places of higher tensions, will result in union consideration, which will later be tested in the IFPI materials testing laboratory. Thus contributing to the understanding and design of a development and analysis of mechanical elements in machines subjected to intense cyclic effort, thus producing greater reliability for parts that act in a similar way to the support.
