Abstract
The design of a Structural Health Monitoring (SHM) systems
is a requirement in the task of improving the safety and
maintainability of the structures. Among the multiple techniques
available for health monitoring, acousto-ultrasonics
(AU) offers the possibility of inspecting large areas of structures
from a piezoelectric active sensor network with a relatively
small number of sensors. This paper proposes the
use of an active piezoelectric sensor network which uses
PZTs transducers working as sensors or actuators in different
actuation phases to inspect a wind turbine structure to
determine the presence of damages by analysing the data
from the sensors with multivariate statistical methods such
as PCA and damages indices in order to discern damages
from the healthy structure.
