The objective of this study was get acquiring dependable results
of MW wind turbine blade performance at work condition to design new-style blade.
Most of the research study on structural analysis of wind turbine blade by make
model test and use the finite element, but there were certain differences from
real MW wind turbine blade. Therefore full-scale experiments were employed in
the research, the strains, stresses and displacements of all parts were gained.
The test results shown that the stress distribution was different at every direction
and work condition and 12~18 m of the blade is the dangerous area.
