    Fuzzy Inference System for Modelling Failure Modes in a Ropeway for Massive Transportation
    (ATLANTIS PRESS, 2015-01-01) Villa, Luisa F.; Quintero Montoya, O. L.; Castaneda, L.; Meja, G.; Universidad EAFIT. Departamento de Ingeniería Mecánica; Estudios en Mantenimiento (GEMI)
    This work uses Fuzzy Inference Systems to model the failure modes of the Metrocable (ropeway massive transportation system in Medellin-Colombia) and to this aim, handle the concept of Condition Based Maintenance (CBM) for the automation of maintenance routine. Maintenance procedures in this massive transportation ropeway system have been designed from manufacturer and improved by expert knowledge trough years of operation, so they can be modeled by fuzzy models. The following work is part of the project ``Diagnostic system of the interface grip-cable of the Metrocable'', developed between the entities COLCIENCIAS, Metro de Medellin and Universidad EAFIT.

    Instrumented study of the wheel-Rail interaction
    (JVE International, 2015-01-01) Zóltowski, B.; Castaneda, L.; Zóltowski, M.; Universidad EAFIT. Departamento de Ingeniería Mecánica; Estudios en Mantenimiento (GEMI)
    This article describes a measurement method whit strain gages, which allows measure the vertical force independently of the lateral force in the wheel - Track interface of a railway. It also shows the obtained results from the implementation of this method to measure the forces in a commercial railway of the railway system. © JVE International Ltd.

    Study of the state a Francis turbine
    (Politechnika Gdanska, Wydzial Oceanotechniki i Okretownictwa, 2013-04-01) Zóltowski, M.; Zóltowski, B.; Castaneda, L.; Universidad EAFIT. Departamento de Ingeniería Mecánica; Estudios en Mantenimiento (GEMI)
    This paper presents a methodology to evaluate the technical state of a Francis turbine by shaft rotor dynamic simulation. There are several rotor dynamic criteria that define the technical state of a turbo-machine. To feed the shaft rotor dynamic model this delivers the required information to accomplish the technical assessment. The numerical rotor dynamic model uses as input, the field forces obtained by the fluid-solid interaction analysis undertaken over the blades of the runner. The rotor dynamic numerical simulations allow to determinate the record-in-time of the displacements of any point along the shaft. This information is relevant for diagnosis tasks, because it is possible to decompose it spectrally and to estimate the severity of the vibrations. Comparing the results of the numerical model against those obtained from machines that operates under normal conditions, it is possible to determinate the technical state of the turbo-machine. This allows studying the stability of the turbine working on several operation ranges. A Francis turbine is a very complex machine that involves many physical phenomena of different nature. In this way, the hydraulic input forces needed by the rotor dynamic model should not be assumed but calculated directly from the fluid interaction over the turbine structure.
