Nastran optimization with preload (centrifugal)
Yes, the blade is the only component. I consider the blade foot clamped, and FE results are very close to ground tests (no rotation) results. The global reason of my problem is that I could find several FE Models as results of optimization (by selecting different design variables, with... -
Nastran optimization with preload (centrifugal)
Hello, I have a Nastran FE model of a blade, which I first managed to optimize in order to fit the best as possible experimental ground measurements (no rotation of the blade = no preload). The .bdf file was roughly as follows: SOL200 ... SUBCASE 1 $ subcase for which responses (DRESPi) are...
