I wish to analyze the performance of two different control methods based on their ability to minimize fatigue damage.
I’m using Crunch to analyze the output data from FAST_v8. I’ve generated RCC files for certain channels. The RCC files contain two columns X and Y for each channel, as stated:
The [X]-values are the peak-to-peak magnitudes of the rainflow cycles.
The [Y]-values are the rainflow cycles per second for those peak-to-peak magnitudes.
However, the [X]- values don’t seem to match for the two files I wish to compare. So I can’t directly compare which control led to fewer cycles.
What would be a good method to compare the two? Can I use “summation XY” for each channel and then use that for comparision?
