Study Notes
Definition and Purpose
- Vibration analysis is a technique used to measure the vibration of machines and structures to identify potential problems and improve their performance and reliability.
- It involves the measurement and analysis of vibration data to detect anomalies, diagnose faults, and predict maintenance needs.
Types of Vibration Analysis
- Time Domain Analysis: Analyzes vibration data in the time domain to identify patterns and trends.
- Frequency Domain Analysis: Analyzes vibration data in the frequency domain to identify specific frequency components and their amplitudes.
- ** Orbit Analysis**: Analyzes the vibration of rotating machines, such as turbines and pumps, to identify imbalance, misalignment, and other issues.
Vibration Measurement Techniques
- Accelerometers: Measure vibration acceleration using piezoelectric sensors.
- Velocity Sensors: Measure vibration velocity using laser or inductive sensors.
- Displacement Sensors: Measure vibration displacement using capacitive or inductive sensors.
- Acoustic Sensors: Measure vibration-related noise using microphones or acoustic sensors.
Vibration Analysis Applications
- Predictive Maintenance: Uses vibration analysis to predict equipment failures and schedule maintenance.
