VIBRATION DAMPING SHEET FOR WIND TURBINE GENERATOR BLADE, VIBRATION DAMPING STRUCTURE OF WIND TURBINE GENERATOR BLADE, WIND TURBINE GENERATOR, AND METHOD OF DAMPING VIBRATION OF WIND TURBINE GENERATOR BLADE

摘要

PPROBLEM TO BE SOLVED: To provide a vibration damping sheet for a wind turbine generator blade which can easily and sufficiently damp the vibration of any portion of the wind turbine generator blade and can secure a reduction in weight, and also provide the vibration damping structure of the wind turbine generator blade, a wind turbine generator, and a method of damping the vibration of the wind turbine generator blade. PSOLUTION: This vibration damping sheet 10 for a wind turbine generator blade includes a resin layer 11 and a restraining layer 12 laminated on the resin layer 11. The vibration damping sheets 10 are stuck on the inner surface of the wind turbine generator blade 4 having a hollow structure, and heated. Consequently, the rigidity of the wind turbine generator blade 4 can be easily and reliably secured by easily and sufficiently damping the vibration of any portion of the wind turbine generator blade 4, and also a reduction in the weight of the wind turbine generator blade 4 can be secured.
