What Is Vibration Analysis?

Vibration analysis is a process that monitors the levels and patterns of vibration signals within a component, machinery or structure, to detect abnormal vibration events and to evaluate the overall condition of the test object.It is commonly conducted both on the time waveforms of the vibration signal directly, as well as on the frequency spectrum, which is obtained by applying Fourier Transform on the time waveform.

Vibration analysis is a powerful tool used to diagnose and monitor the condition of industrial machinery. It involves measuring and analyzing the vibrations of machines to identify faults, defects, and potential failures.

Vibration analysis is critical for ensuring the safety and reliability of machinery in various industries, including oil & gas, power generation, mining, aerospace, marine, and manufacturing. By monitoring machine vibrations, companies can detect issues before they lead to costly breakdowns and downtime, minimizing maintenance costs, and maximizing equipment longevity.

The process of vibration analysis involves three main stages: data collection, analysis, and interpretation. During the data collection stage, sensors are attached to the machine being analyzed to measure vibrations over time. This data is then input into specialized software that analyzes the vibration frequencies, amplitudes, and patterns.

The analysis stage involves interpreting the data collected during the previous stage to identify potential faults and defects. Sophisticated vibration analysis software can even predict when a machine is likely to fail, providing ample time to schedule maintenance or repair works before it happens.

Finally, during the interpretation stage, the results of the analysis are presented in an easily understandable format, such as a report or dashboard, highlighting the condition of the machine and any recommendations for optimization.

There are several types of vibration analysis techniques available, each offering different insights into a machine’s condition. These include:

  1. Time domain analysis: This technique measures the amplitude, frequency, and phase of vibration signals over time, allowing for accurate diagnosis of faults such as imbalance, misalignment, and bearing wear.

  2. Frequency domain analysis: This technique uses Fourier transforms to convert time-domain signals into frequency spectra, enabling visualization of individual vibration components and identification of specific fault frequencies.

  3. Modal analysis: This technique uses advanced mathematical models to identify the natural frequencies and modes of vibration of a machine, helping to diagnose issues related to structural integrity.

  4. Operational deflection shape analysis: This technique measures the vibration of a machine while in operation, providing insights into how it deforms under load and identifying potential structural issues.

In conclusion, vibration analysis is a critical tool for ensuring the safe and reliable operation of industrial machinery. By detecting faults and defects early, companies can reduce maintenance costs, minimize downtime, and extend machine life expectancy. With advances in technology and software, vibration analysis has become more accessible and affordable, making it an invaluable asset to industries worldwide.

Process Of Vibration Analysis at ANSH 3D

Vibrations can be represented in different forms, including displacement, velocity, and acceleration.

Step 1:- Sensor installation
Sensor installation is critical for ensuring that high-quality data is recorded. When selecting suitable vibration sensors, the vibration levels/dynamic range and maximum frequency range/bandwidth should be considered, as well as the other operating environments such as temperature, humidity, and pH level..

Step 2 – Choosing a sampling rate
Vibration signals are usually below 20 kHz, except for certain vibration resonances that can reach beyond that. In practice, the sampling rate should be carefully chosen, to
make sure that the bandwidth containing frequencies of interest is captured.

Step 3:- Conducting vibration analysis through Vibration Monitoring analysis
The vibration monitoring system processes the recorded vibration and translates the information to intuitive indications for the machine operators, maintenance staff or asset managers. This information is then used to conduct vibration analysis.

Vibration analysis is predominantly applied for the condition monitoring on machinery and their key rotating parts, structural health monitoring etc.
