<P>PROBLEM 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. <P>SOLUTION: 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. <P>COPYRIGHT: (C)2011,JPO&INPIT |
