Análise de falhas mecânicas no sistema de tracção das locomotivas da General Electric

Abstract

The railway sector, like other areas of the Mozambican industry, is constantly seeking to increase the efficiency of its assets. Therefore, there is a need to implement tools that help in the identification and prevention of failures. Failures are characterized by the inability of an asset to perform a required function and represent an interruption in the production process, compromising the availability of assets and reducing competitiveness. Therefore, the control and prevention of failures becomes crucial, hence different analysis tools are available and help in the control and prevention of them. According to data provided by the company Caminhos de Ferro de Moçambique, the element with the highest number of failures in the locomotives is the traction engine. This high number of occurrences is due to the operating conditions that this element is subject to, and can cause problems in the operation of companies in the sector, consuming a high volume of resources, time and capital. Thus, there is a need for a study to prevent these occurrences. This work proposes an analysis of the failures that occurred in these engines, in order to find their root causes and propose possible solutions for them.
