Vibration Monitoring is the method of understanding and reporting on vibration, both man made and natural. This is completed to monitor the affects to both human safety and structural integrity as a result of either man made or natural vibrations.
It is common practice in the industry of noise & vibration monitoring, but why is it so important?
The Effects of Vibration
Vibration, in small doses, is relatively harmless. But in excessive amounts, it can lead to a range of problems and could even be life threatening. Problems such as:
- Structural damage: Prolonged exposure to vibration can weaken structures, leading to cracks and fractures which could lead to structural collapse.
- Health Impacts: Vibration can cause discomfort, fatigue and long-term injury to individuals exposed to high amounts of dangerous vibration.
- Equipment Malfunction: Machinery and equipment that is sensitive to vibration will be prone to malfunction and premature wear and tear when in unsuitable environments.
So Why Should We Monitor Vibration?
Given the potential risks that are associated with high levels of vibration, it is essential that when working in these environments, we are aware of the vibration levels.
Robust monitoring allows for early detection of excessive vibration, enabling proactive action to be taken when levels go above a certain threshold.
For example: Construction work is happening underground, if vibration levels reach a certain level, this could damage the surrounding area, potentially affecting the foundations of buildings, damaging their structural integrity. If left unmonitored, long-term exposure could have catastrophic effects.
This also ensures that when working with high levels of vibration, you are complying with regulations set out by governing bodies, such as local councils or health & safety advisers. Helping you avoid fines and sanctions while maintaining the safety of the surrounding area and people.
Safety is a big concern, when people have been exposed to high levels of vibration, they can develop something known as Hand-Arm Vibration Syndrome (HAVS). This is especially prominent in the construction industry, where people use heavy machinery like – concrete breakers, pokers and compactors, sanders, grinders and many more.
Those affected can experience difficulty carrying out tasks involving fine or manipulative work and everyday tasks, such as fastening small buttons on clothes, become a problem too. Working outdoors in cold conditions, which is common in construction work, increases the likelihood of a painful response.
This damage to the hands is largely irreversible. – HSE Gov
Vibration Monitoring Techniques
So we know that vibration monitoring is important, but how do we monitor it?
There are multiple techniques to conduct vibration analysis. They each offer unique advantages and applications, however there are 2 common methods of vibration analysis.
Accelerometers
Accelerometers are sensors that measure acceleration forces. In the context of vibration monitoring, they detect vibrations by measuring the rate of change of velocity of an object. This means that they are mainly used for the following:
Condition Monitoring: Monitoring the health and performance of machinery and equipment in industries such as manufacturing, automotive, and aerospace.
Structural Health Monitoring: Assessing the structural integrity of buildings, bridges, and other infrastructure.
Seismic Monitoring: Detecting and analysing ground vibrations caused by earthquakes and other seismic events.
Pros:
- High sensitivity to small vibrations.
- Wide frequency range.
Geophones
Geophones consist of a coil of wire suspended in a magnetic field. This generates an electrical signal in response to ground movement. They are primarily used for ground measurements, meaning their applications consist of:
Construction: Monitoring vibrations generated by construction activities such as pile driving, blasting, and heavy machinery operation to prevent damage to nearby structures.
Mining: Assessing ground vibrations induced by mining operations to ensure worker safety and minimize environmental impact.
Seismic Exploration: Detecting and analysing seismic waves to locate underground resources such as oil, gas, and minerals.
Pros:
- High sensitivity with minimal impact on battery life.
- Suitable for prolonged monitoring.
