Dealing with periodical loads and harmonics in operational modal analysis using time-varying transmissibility functions
TOMA is an OMA-technique that is unaffected by harmonics or periodical loads. Introducing time-varying transmissibility functions for TOMA. TOMA becomes possible for non-stationary loading conditions. The analyst does not longer have to identify different loading conditions. A lab-experiment demonstrates time-varying TOMA.
