Rotating System Measurements using the Open Acquisition System for IEPE Sensors (OASIS)

Stationary and dynamic measurements of an academic test structure with a topology similar to a
wind turbine, performed using the Open Acquisition System for IEPE Sensors (OASIS). The
system is excited using a shaker and band-limited random noise.
<br>
Data structure: File names either end with 'ONE' or 'TWO'; this refers to the acquisition system id.
Stationary measurements are in the folder 'stationary'. File names start with '*deg', where * is the
blade angle for those measurements, followed by a number indicating the run number. Dynamic
measurements are in the folder 'dynamic'. File names start with '*Hz', where * is the rotational
frequency for those measurements, followed by a number indicating the run number.

Channel assignment: OASIS ONE - Ch. 1 to 4 are acceleration sensors mounted along the blade,
where 1 and 4 are at the tips of the blades. OASIS TWO - Ch. 1 excitation force, Ch. 2 light barrier
signal (2x per rotation), Ch. 3 acceleration in excitation direction, Ch 4. lateral acceleration.
