Study Notes

Vibration Analysis

Vibration analysis is a method to monitor and analyze the vibration of machinery and equipment to detect potential problems.

Data Collection

Data collection in vibration analysis involves actions such as:
- Installing sensors like accelerometers on machinery to measure vibration
- Collecting data on vibration levels, frequencies, and other parameters
- Transferring data to a data collector or analyzer

Data Collector

The data collector records vibration data, including amplitude, frequency, and time information.

Accelerometer

An accelerometer is a device used to measure vibration in machinery.
The voltage signal from the accelerometer corresponds to the vibration acceleration.

Vibration Analysis Methodology

Components involved in vibration analysis methodology include:
- Sensors (e.g., accelerometers) to measure vibration
- Data collectors or analyzers to record and process data
- Software for data analysis and diagnosis

Vibration Analysis Terminology

Terms in vibration analysis include:
- Acceleration: the rate of change of velocity
- Amplitude: the magnitude of vibration
- Frequency: the number of cycles of vibration per second
- Phase: the angle between a vibration signal and a reference signal
