Mass Loaded Blade Test-UW Madison

This test was performed in early January 2012.

One set of measurements was taken.

The hammer was roved over approximately 20 points to obtain a fairly dense pattern of points.

Mass-Loading Fixture

To mass-load the interface, a block of steel was sandwiched between two aluminum plates, similar to how the blade is held by the wind turbine. This added mass represents a type of transmission simulator for the blade. It is mostly rigid in the frequency span of interest.
