Structural Vibration & Resonance

What this topic covers

How repeated excitation interacts with natural structural frequencies.

Core monitoring ideas

Resonance occurs when excitation aligns with a structural dynamic response.

Machinery, wind, traffic or process cycles can provide repeated excitation.

Changes in frequency or damping are informative only with context.

Interpretation limits

Environmental and operational changes can mimic damage-related trends and should be included in interpretation.

Evidence and data quality

Direct inspection remains important when a signal suggests a local defect or geometry change.

Lifecycle use

This site does not calculate safe remaining life, structural capacity or return-to-service criteria.
