There are several strategies for maintenance and repairing of devices in industry. However, they are still confronted with many uncertainties. A hydraulic lifting device after ten years of working in a technical center in Isfahan is faced with uncertainty in terms of reliability. Being able to know the reliability of pieces means predicting failure occurrences, which is accomplished by conditio...

    Condition Monitoring,   Oil Analysis, Wear Behavior,   Fuzzy Rule Based System   Maintenance , as a support function, plays an important role in manufacturing companies and operational organizations. In this paper, fuzzy rules used to interpret linguistic variables for determination of priorities. Using this approach, such verbal expressions, which cannot be explicitly analyzed or statistic...

Condition Monitoring of rotating equipment has been a very important aspect in the field of maintenance engineering. There are various types of condition monitoring techniques, namely: Vibration Analysis, Oil Debris Analysis, Ferrography, Temperature analysis. Among all these techniques, vibration analysis have gained much importance in the field of condition monitoring because of its accuracy ...

The present paper addresses systematic approach to Condition-Based Maintenance, and research results at the University of South Carolina Condition-Based Maintenance Research Center, directly related to U.S. Army rotorcraft Vibration Management Enhancement Program. The paper gives an analysis of the CBM concept and its functional layers, such as condition monitoring, diagnostics, prognostics and...

The ability to monitor the condition of an electrical machine has been a concern of industry for many years. Knowing when a machine requires maintenance allows users to perform the required maintenance at their convenience, rather than during costly unscheduled shutdowns. This need for improved industrial monitoring techniques has produced a number of studies on the detection of mechanical faul...

Maintenance of a sensor part typically means renewal of the sensor in regular intervals or replacing the malfunctioning sensor. However optimal timing of the replacement can reduce maintenance costs. The aim of this article is to suggest a predictive maintenance strategy for sensors using condition monitoring and early failure detection based on their own collected measurements. Three different...

Smart manufacturing is the modern form of that utilises Industry 4.0 enablers for decision making and resources planning by taking advantage available data. Therefore, state art technologies are either replaced or improved using newly introduced paradigm. In practice, condition monitoring an on-going activity preserves facility capability to deliver its production aims decrease discontinuity as...
