Well, it doesn’t look like much but those two guys on the picture are smiling. And how do we know that? Because they are not wearing a mask! In public! Ah, those were the days …
On this occasion, I presented a simple addition to the modal method for creating compact – though accurate – state space models for mechanical systems submitted to thermal disturbances.
Then, I applied it to a synchrotron light source primary mirror. This is a typical case where the figure of merit (here: slope error) is dominated by the local, quasi-static response (here: bump) which would be grossly underestimated when not including static correction. I also show that the brute-force approach (including hundreds of modes) would very slowly converge to a … very inaccurate value. The presentation can be downloaded here:
