Outline of Final Research Achievements |
In this study, we successfully developed the distributed fiber-optic sensing system which can measure strain distributions with high spatial resolution and high speed along an optical fiber. In addition, we developed a method to evaluate such a unique sensor. Then we applied this system to identifications of load distribution and deformation in a wind turbine blade model and a plate by using inverse analysis based on measured strain information. This result is expected to be incorporated into a control system which is able to suppress overloading and harmful deformation of large-sized wind turbines and contributes to a safer and more reliable operation.
