Definition

Vibration Analysis is a technique for diagnosing equipment condition by measuring and analyzing vibration signals from mechanical equipment. It evaluates equipment health by precisely measuring oscillatory motion about an equilibrium point, identifying both deterministic vibration patterns and random vibration characteristics.

Application in Manufacturing

Predictive Maintenance

Vibration analysis is a core technology for early detection of anomalies in rotating machinery. It enables planned maintenance by detecting issues such as bearing wear, shaft misalignment, and imbalance in advance.

AI-based Fault Prediction

Recently, machine learning algorithms learn from vibration data to automatically recognize fault patterns. Through time-series data analysis, they monitor deviations from normal states in real-time and predict failure occurrence timing.

Key Points

Frequency Analysis: Identify specific fault types by decomposing vibration frequency components using FFT (Fast Fourier Transform)
Sensor Placement: Install accelerometers at critical locations such as bearing housings and motor frames
Threshold Setting: Set alarm levels based on ISO standards for early anomaly detection
Data Integration: Integrate with SCADA systems for combined analysis with production data

Vibration analysis is an essential technology for increasing equipment uptime and minimizing unexpected downtime in manufacturing facilities.
