The windmill hub example

Establish a Finite Element model of the Hub with shafts, bearings and gears

Calculate Hub global and local stresses and accelerations based on unit aerodynamic loads

Identify maximum stress concentration factor areas

Based on Finite Element results, identify sensor positions

Establish Strain gauge and/or accelerometer positions and directions

Start monitoring

Correlate Finite Element results with monitoring results

Link results to the CAE Fatigue software

Calculate remaining fatigue life
