Dear Jason,
Thank you for your fast reply.
I remembered I asked you a similar question about the fatigue load evaluation in this forum[url]Question #1 for turbulence fields (points outside of field)].
I only have a single time series of results, you recommend me to use STD or RMS of moments to evaluate the fatigue load. However, just as you said, the same oscillation about a higher mean moments leads to same STD but higher RMS, I’m confused now, which performance index is better, STD or RMS.
Since I used STD to evaluate the fatigue load (of tower base and blade root) in my previous work, i.e., I want to get smaller oscillation. If I use IBP to reduce the amplitude of blade bending moments, I’m not sure I will get small STD of blade bending moments.
Best regards,
Cheng
