Redimensionamento de componentes mecânicos a partir da análise de falhas em um elevador de fardos de fumo.

Abstract

This work presents a study on failure analysis methods and the application of the FMEA methodology (Failure Modes and Effects Analysis) in functional elements of a tobacco bale elevator, aiming to propose resizing measures for components prone to failure. The research was conducted based on the FMEA methodology to be followed for the completion of the work, with one of the results being the calculation of the RPN (Risk Priority Number) and subsequent prioritization of failures. Through this, an equivalent theoretical survey was carried out to perform the necessary dimensional analyses and identify characteristics in relation to the current safety factor of the project components, suggesting a redesign when it does not meet the stipulated limit. As a result, it was identified that out of the 37 components analyzed, 7 required a dimensional analysis to verify if their sizing was consistent with the high RPN presented. It is concluded that the FMEA analysis proved to be efficient for the analysis and resizing of mechanical components in the tobacco bale elevator.
