Projeto, desenvolvimento e modelagem de uma bancada experimental sujeita a cargas de flexão e torção

Abstract

Increasingly a demanding industry of means that guarantee speed, security and high quality in its projects and products. In this context, an analysis of the behavior of structures constituted in important part of the product development, economic and practical difficulties, associated with the evaluation of the behavior by means of real scale tests, estimated the development and use of numerical simulation methods, able to Represent Satisfactorily the behavior of reals. In general, the structures are very complex for numerical simulations, which entails a need for robust computers and a significant time for data processing. To overcome these difficulties, a much simpler model, such as a swing beam, can approximate such structures. With this in mind, this work aims at the design and numerical modeling of a beam and its components of fixation of the structure, subjected to bending and twisting loads. This design can be used to physically fabricate the structure, and thus enable engineering students to conduct static and dynamic behavior studies of similar structures. A methodology adopted considers a position in free conditions, of steel with profile in format, design in CAD environment and numerical model in a software that is based on the Finite Element method. For static analysis in a simulation environment, it is defined as boundary conditions and applied to the free end of the swinging beam, generating deflection until material is deformed near the resistance limit, according to the Von Mises criterion, the data are analyzed and used for the analytical dimensioning of the fixation components of the structure.
