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
