REal time CONDITION monitoring and maintenance.
Have you ever wondered how heritage structures, old buildings, bridges, and dams still stand the test of time? The answer simply lies in Condition Monitoring and Maintenance. As engineers, we try to find (satisfactory) answers to the basic questions - 'What', 'Why', 'How', and necessarily, 'Where'.
The 'What' of the thought:
In my (limited) years of experience in this area, I would like to put 'Condition Monitoring and Maintenance' as an 'Engineering' process that checks the 'Condition' a system is at and directs 'Maintenance' to preserve - and possibly enhance - its useful life.
In the past two decades of accelerated technological development, the reliance on structural and mechanical systems such as aircrafts, buildings, bridges, railways, power generation systems, and defense systems is on a steady rise. A significant portion of the built infrastructure could benefit from extensive condition monitoring and data-driven, informed maintenance. However, constraints such as improper planning, negligence in management and unavailability of adequate resources impede their systematic implementation. Operation - within and sometimes - beyond the initially designed service life requires assessment of the system in relation to performance metrics considering aging and sustained degradation. This requirement leads to the need of efficient damage detection techniques in order to detect and locate the damage, estimate the severity of the damage and predict the useful remaining life of a structure, often referred to as structural health monitoring (SHM) analysis.
This blog will sequentially provide ideas on RE-CONDITION and SHM, and derive the differences between the two. The blog series is directed towards researchers, individuals, and practitioners who would wish to benefit from structural and system monitoring techniques. With old-age construction facilities slowly taking the backfoot, the prominence on real-time and online fault detection strategies are gaining importance. My work is primarily based on real-time approaches - however, I will, in subsequent blogs - help you identify the differences between the methods, along with the advantages associated with online techniques.
Simple explanation and concise technical investigations will be the key characteristics of this blog series. I am always open to suggestions for improvement, constructive criticisms, and refute on thought processes.
