Desenvolvimento de bancada de testes para avaliação dinâmica de eixos rotativos sob a ação de massas desbalanceadas
(2023-11-08)
This study aims to develop a didactic balancing machine for vibration analysis in rotating elements. The vibration transmitted by unbalanced masses to the bearings can cause operational interferences as noises and even ...
Análise da substituição de uma geradora de água quente alimentada por gás liquefeito de petróleo por uma geradora alimentada a pellet
(2023-11-24)
The history of global industry is directly linked to the use of fossil fuels as an energy source, especially liquefied petroleum gas (LPG), which has been used for decades in the most diverse production sectors. It is ...
Análise crítica operacional de um equipamento protótipo para ensaios de fadiga por flexão rotativa
(2023-11-29)
The application of fluctuating or repetitive stresses on materials causes fracture to occur at stresses much lower than those determined by static tensile or compression tests. This failure caused by alternating forces is ...
