New Measurement Concepts

using optical fibers

Estimating remaining lifetime

Removing operating and

ambient influences

CASE 5: CONTINUOUS MONITORING OF

DYNAMIC BEHAVIOUR OF THE DRIVE TRAIN

IMPROVED DESIGN + O&M

Optimal design and maintenance insure

the well functioning of a wind turbine drive

train including the gearbox

Both simulation models and optimized

measurement techniques are needed to

achieve both goals

Combining gearbox surface vibration data with internal flexible

multibody models to retrieve information on the relevant parameters

for the remaining life assessment of wind turbine gearboxes
