N2 - This report is a part of the research project “Eksperimentel
vingeforskning: Strukturelle mekanismer i nutidens og
fremtidens store vinger under kombineret last” where a 34m
wind turbine blade from SSP-Technology A/S has been tested
in edgewise direction (LTT). The applied load is 60% of an
unrealistic extreme event, corresponding to 75% of a
certificated extreme load.
This report describes the background, the test set up, the tests
and the results.
For this project, a new solution has been used for the load
application and the solution for the load application is described
in this report as well.
The blade has been submitted to thorough examination. More
areas have been examined with DIC, both global and local
deflections have been measured, and also 378 strain gauge
measurements have been performed.
Furthermore Acoustic Emission has been used in order to detect
damage while testing new load areas.
The global deflection is compared with results from a previous
test and results from FEM analyses in order to validate the
solution as to how the gravity load on the blade was handled.
Furthermore, the DIC measurement and the displacement
sensors measurements are compared in order to validate the
results from the DIC measurements.
The report includes the results from the test and a description of
the measurement equipment and the data acquisition.
