Thanks Jason as always for quick and clear answer !.
My purpose is to analyze a single blade and not go for wind farm or spatio-temporal scope. I want to calculate time varying loads or pressure on the 17 sections of NREL 5 MW land based blade and do fatigue analysis in Ansys. Based on the discussion so far with you, here is the summary of options
- Use of ForcN, ForcT - Ruled out since they do not consider inertial loads
- Use of SpniFLxbi…SpniMLxbi - These are possible candidates as they include applied load + interia effect
(Question Regarding NREL Phase VI FAST Model - #8 by Jason.Jonkman)
For option 2 I could calculate the equivalent loads for each section as per Yahya’s suggestion Stress Analysis of Blades and a Tower. However I was thinking of having a way to calculate pressure on airfoils instead of point loads. If there is no other option then should I go with option 2 above?
Secondly, if I want to use time-domain method (weibul wind—>rainflow counting—>stress range–>Fatigue life analysis process) instead of spectral density method then is there any way to calculate wind velocity components?. I believe TubSim is a spectral analysis tool
