REMAINING SERVICE LIFE EVALUATING DEVICE AND METHOD, AND WIND POWER ELECTRICITY GENERATING SYSTEM

摘要

The objective of the invention is to evaluate accurately the remaining service life of a composite material structure.A composite material structure remaining service life evaluating system 5 is provided with: a loading history evaluating unit 7 which calculates a history of loading with respect to a composite material, from a first sensor provided in the composite material; a state quantity evaluating unit 10 which calculates a state quantity of the composite material from the first sensor or a second sensor; a state quantity variation database 13 in which relationships between loading histories of the composite material and the state quantity are recorded in advance; and a comparing and evaluating unit 12 which compares the calculated loading history and state quantity with the loading histories and state quantities recorded in the state quantity variation database 13.
