Periodic Component

This calculation separates out the periodic and stochastic parts of a signal.

Click the Select... buttons to define the signal to be processed and the signal representing rotor azimuth. If you have selected multiple channels you will be able to specify a number of load cases and variables to be processed in a single calculation, and the results for each load case will then be stored as additional outputs of that load case. Then choose either automatic or manual selection of data. Automatic selection is usually adequate, but if entered manually, the parameter required is:

  • Number of bins: the number of azimuthal bins to be used in the calculation (minimum 4, maximum 144). More bins will generally give a more accurate result, but do not choose more bins than the number of signal samples in one revolution of the rotor.
