The high cost of the rail transport maintenance can be split into the permanent way cost and the rolling stock. This last one, represented in Brazil for the diesel-electric locomotives, the item more expensive is the diesel ...

The main objective of this research is to identify the main cause of impact on asset availability. It is of fundamental importance to understand the causes of impact on asset availability, due to the great impact that it ...

The focus of this research is to analyse one of the most important locomotive component, the traction motors. These motors must have high reliability to provide efficient rail transportation. Altough in the last three years ...

The Traction Motor (TM) is a component in charge for the traction of a Diesel Electric Locomotives. The work environmental in which it operates is very aggressive and has different realities as the temperature and moisture ...

Efficient equipment maintenance managemet remains one of the main challenges for organizations, which rely on selection of the most suitable tasks for failure rate control. Brazilian railway operation demand on adequate ...

This paper describes the fabrication, implementation and results of a fiber optic sensor based on Bragg gratings regenerated for measurement of high temperatures of the exhaust gases in a turbine diesel engine locomotive. ...

This paper presents the design report for an analog IGBT SPICE model, part number 2MBI1200U4G-170. The modeling was perceived as a interesting tool in order to analyze the switching times and losses during the development, ...

Railway transport is an important mode of transport and the vehicle used to move freight or passenger trains is the locomotive. One of the most used types of locomotive is the diesel-electric locomotive, characterized ...

Normalmente em locomotivas diesel-elétricas a energia gerada durante a frenagem é dissipada em banco de resistores por meio de um sistema de frenagem dinâmica. Para realizar o aproveitamento dessa energia, pode-se fazer ...
