Poorly maintained roads are a fact of life in most developing countries; it is certainly the case in Sri Lanka. The lack of funding to maintain the road surfaces is a main reason for the dilapidated condition of roads in these countries, but it is not the only reason. The absence of an effective monitoring system is one reason for this problem. A monitoring system can help to take remedial acti...

The packaging materials industry has already recognized the importance of Total Productive Maintenance as a system of proactive techniques for improving equipment reliability. Bearing faults, which often occur gradually, represent one of the foremost causes of failures in the industry. Therefore, detection of their faults in an early stage is quite important to assure reliable and efficient ope...

The use of condition monitoring systems on wind turbines has increased dramatically in recent times. However, their use is mostly restricted to vibration based monitoring systems for the gearbox, generator and drive train. There are many forms and types of condition monitoring systems now available for wind turbines. A survey of commercially available condition monitoring systems and their asso...

The Reliability Centred Maintenance strategy aims at deciding predictive maintenance tasks on process equipments. The approaches such as FMEA, HAZOP and FTA are most widely used analytical tools for identifying the predominant failure modes, failure causes and possible remedial measures thereof. The success of predictive maintenance program lies in raising an appropriate ‘Early Warning’ with th...

Predictive maintenance is closely connected to condition monitoring, health and usage monitoring systems (HUMS), prognostic modeling and condition-based maintenance (CBM). It is concerned with identifying what maintenance actions should be chosen and when, based on the predicted state of the item of interest over time. It can be viewed as a logical development of CBM. The authors of this paper ...

Failure of equipment not only leads to loss of production, but also, in some serious situations, causes human casualty. Hence, the need of equipment condition monitoring becomes crucial for reliable operations. Since expensive hardware instruments are needed for condition monitoring, with the current powerful PCs, software based virtual instruments are possible to replace hardware instruments. ...

This paper presents results from a case study in predictive maintenance at a distribution warehouse. A simulation model was built with ARENA 5.0 for integrating predictive maintenance strategies with production planning strategies, for a conveyor system. Equipment health was monitored using condition-based parameters such as temperature and vibration for mechanical and electrical components su...

structural health monitoring of cracked structures is one of beloved subject of researchers recently. consider of crack behavior in the water and energy pipeline is important because of environmental problems. in this paper consider of crack parameters in the underwater pipe subjected to mechanical transient load is investigated. for this purpose, three- dimensional parametric model of cracked ...

Condition-based maintenance (CBM) seeks to implement a policy wherein maintenance management decisions are based on the identification of the current condition of monitored machinery. It involves not only collecting data but also comparing them with reference values and, if necessary generating alerts based on preset operational limits. This approach is adopted by a system responsible for monit...
