Análise modal de uma viga utilizando sensor acelerômetro

Abstract

The Modal Analysis is one of the most important tools within the field of study in Mechanical Vibrations, is a method used to obtain the modal parameters of a structure using response signals when excited by an external force. However, it is an area little widespread in academic at the Universidade Estadual do Maranhão (UEMA). This research consisted in the construction of an experimental model with simplified complexity, using a beam with a degree of freedom, in order to open doors for the development of even more profound studies in this area. In this work, is also discussed the use of the accelerometer sensor data acquisition, very important for the realization of experimental modal analysis (AME). The incorporation of new technologies in structural testing, can add new knowledge and advances in this branch of research
