Estudo da confiabilidade de sistemas de colhedoras de cana-de-açúcar

Abstract

The constant demand for an increase in the sugarcane harvest and profit has resulted in new demands for the industrial sector, leading sugarcane harvesters to become increasingly dependent on control and automation technologies. At the same time, there is a need to reduce the occurrence of failures in these machines, which increase production costs. However, the adoption of new methods must be researched upstream to ensure that the objectives sought by the maintenance team are achieved. In this sense, this work presents a case study, explaining the concepts and applying the maintenance reliability analysis, from the collection of data from fifty sugarcane harvesters of a bioenergy company. In addition, reliability results of each vehicle system of the analyzed harvesters are presented with the construction of the reliability block diagram, according to the exponential model of failure probability distribution, identifying critical components of the equipment and presenting strategies to prevent unforeseen failures of this component, thus allowing to improve the performance of the equipment.
