Parameter Estimation Techniques for Modal Analysis
Abstract
Parameter estimation techniques that can be used to determine modal parameters (frequency, damping, and mode shape) from experimentally measured frequency response or unit impulse response are presented with respect to practical implementation and use. The methods are separated into two categories: 1) A curve fit of only one degree of freedom with or without residuals. 2) A curve fit of multiple degrees of freedom with or without residuals. Particular details are given with respect to multiple degree of freedom techniques utilizing the Complex Exponential algorithm.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
