Vibration analysis refers to the measurement and analysis of vibration data (e.g. displacement, velocity and acceleration), in order to monitor and advise on the condition of machinery and equipment as well as the possible required maintenance and remedial actions.
Vibration analysis is an integral part of condition-based monitoring / predictive maintenance (which is based on determining the condition of machinery and equipment while in operation). Such monitoring / maintenance is dependent on the fact that most machine components will provide some warning or other indication (e.g. significant increase in vibration or specific patterns in vibration spectra) before they fail, and in fact, it is often possible to determine the likely fault condition. For instance, the existence of particular patterns in vibration spectra can indicate whether a machine suffers from misalignment, unbalance, rolling element bearing wear / defect, looseness, etc.
The potential benefits of condition-based monitoring / predictive maintenance include: (a) less downtime; (b) reduced expenditure for spare parts and labour; (c) greater certainty of proper alignment and overall integrity of the machinery / equipment; and (d) reduced likelihood of catastrophic failure (thereby increasing worker / plant safety).
A typical condition-based monitoring programme involves the following steps (on a monthly basis): (1) we visit our client’s site / plant to collect vibration data from the various machines; (2) we compile and analyse the vibration data; and (3) we provide an analysis report setting out all relevant observations, issues / concerns and recommendations.
We currently run long-term vibration analysis / condition-based monitoring programmes for major petrochemical and pharmaceutical plants in Singapore.
