Abstract
Lamb wave based damage imaging monitoring technique was studied for real-world wind turbine blade structure based on the mechanism of active Lamb wave damage monitoring. The basic framework of the monitoring system and the module demonstration system implementation scheme were given in which the piezoelectric array and the RAPID tomography technique were adopted to realize real-world blade structure online monitoring and evaluation. The results of the experiments showed that the monitoring system could detect the damage online and directly show the appearance, location and other information of the damage. It indicated that the proposed system should be helpful for the operation and maintenance of the wind turbine blade structure.
