Abstract
The present study aims to evaluate the features present in a didactic equipment built for the study material enhancement of an academic laboratory. The main purpose of this equipment is to simulate vibration defects and its correction through the use of accelerometers and its signal analysis interpretation. This would adequately demonstrate the effects of vibration defects in a rotating machine, exploring its structure stiffness and level of defects. An enhancement is expected in the quality of practical studies of the UTFPR Mechanical Engineering community. The assembling process is described concerning the material used which directly impacts in the structural stiffness, thus, level of observed vibration. The evaluation methodology is based on the signal analysis of the observed vibrations. In order to reach the correct readings, the equipment had to undergo alignment and balancing procedures. The results show that the identification of both defects, misalignment and unbalance were possible while comparing the literature with the resulting signal analysis charts. It was also possible to analyze how does the structural stiffness and damping influence the vibrations amplitudes. The validity of the proposed didactic equipment was verified through the measured vibration spectrum, which results shown to be in accordance with literatures.
