Adaption And Optimization Of The Ibrahim Time Domain (Itd) Modal Parameter Identification Algorithm For Mini-Computer Use, Mary T. Cogeos

Retrospective Theses and Dissertations

Conventional modal analysis is performed using FFT Analyzers with modal analysis software developed by one of many test/analysis software vendors. The analysis is performed in the frequency domain using frequency response functions. A recent advancement in modal analysis involves analyzing the measured free response of a structure in the time domain. The Ibrahim Time Domain (ITD) Algorithm is such a method which has been used and verified at government environmental test facilities. The ITD is an accurate numeric solution. Minimal operator interaction is required for proper performance of the algorithm. The results of the ITD Algorithm are far superior to …
