...point. The ramifications of this property of the frequency response matrix are that we need not. measure all nine frequency response measurements to obtain the modal parameters. By. selecting one exciter location and measuring the response at all three points or by fixing the. response location...

...identified.Multiple Input Stepped SineMIMO stepped sine testing is based on the simultaneous excitation of the aircraft through a multi-exciter configuration, loading the structure with uncorrelated stepped sine excitation. It provides either MIMO FRFs to be used in the modal analysis phase or response spectra...

...and vibration, shaft alignments, bearing performance, rotor repair requirements, modal analysis and in-situ balancing, on over 20 GW of plant. 2 Comments. 344 days ago Terry Nichols. Very interesting. I wonder why the problem occurred after an outage? Perhaps I should have expected it. Those SS...

Due to the broad frequency range to be assessed and the excessive modal density at higher frequencies, Alenia selected two different modeling technologies: the deterministic Finite/Boundary Element Modeling (FEM/BEM modeling) of LMS SYSNOISE for frequencies up to 125 Hz, and Statistic Energy...
