Abstract
This report describes the second phase of a project to develop fatigue prediction procedures. In the first phase of the work, WTG rotor loads were synthesised in the time domain and a standard rainflow counting procedure was then used to assess the fatigue cycle distribution. The results indicated that a spectral definition of stochastic strain contains sufficient information to allow a realistic assessment of strain cycles for fatigue damage prediction. Time history synthesis was, however, only intended as a first step towards a wholly frequency domain design tool. The objective of the present study was to investigate statistical techniques for predicting fatigue life directly from spectral definitions of rotor loads. The final product would enable fatigue life prediction to be carried out at the parametric study phase of WTG rotor design. (author)
