Modal Analysis Using Operating Modal Identification Method
Chinese Journal of Aeronautics, 2004 AbstractSometimes it is very difficult for some large scale operating structures to measure the input forces. Modal parameters must be estimated on response only. A poly-reference time domain operating modal identification complex exponential method is presented since cross-correlation functions have the same form as impulse response functions.
