Monitoring task and sensing route

Mechanical response needs separation from slow thermal drift. Speed, torque and rotation direction provide interpretation references, while bonding affects local readings.

Published research observation

Luo and colleagues used OFDR in a full-scale wind-turbine gearbox bench test, comparing ring-gear strain responses at different input torques. [1]

Research observationRing-gear strain related to applied loading
Proposed comparisonDocument the fiber direction, bonded locations and distance coordinates, with temperature references.

Validation and integration priorities

Synchronize speed, torque, direction and start-stop events, separating steady and transient operation.

Check repeatability across independent load cycles and review local anomalies with bonding and mechanical inspections.
