Temperature-dependent MIMO transfers 
Following up on previous post presenting our two-step standardized strategy to tackle parametric EMA, this one illustrates its implementation where the varying parameter is the temperature.
The data is part of our tutorials for parametric experimental modal analysis on the GARTEUR test case with temperature dependency. The test being MIMO, the transfers span a frequency band, outputs, inputs, and several temperatures, making it a 4D database.
Data are split into MIMO transfer blocks corresponding to each temperature value. The two-step algorithm is then performed:
1- Transfers corresponding to the first temperature are loaded and EMA is performed (here using the automatic interpretation of LSCF stabilization diagram).
2- Automatic optimizations of poles from current temperature to the next are sequentially performed.
The following video shows the use of this algorithm using GUI.
This algorithm has also been applied to analyze
Modal property dispersion in batches of similar components Mode tracking with excitation amplitude level Other currently ongoing projects
We will showcase other applications in later posts, stay tuned !
