Abstract: [cze] [eng]
Příspěvek se zabývá měřením frekvenčně modálních a tlumicích vlastností aeroelastického modelu navrženého pro experimenty v aerodynamickém tunelu. Na základě experimentální modální analýzy jsou identifikovány matice tuhosti, tlumení a hmotnosti systému. Hranice stability, tj. kritické rychlosti flutteru byly měřeny v aerodynamickém tunelu. Frequency modal and damping characteristics of an aeroelastic model designed for experiments in the wind tunnel are studied. Based on the experimental modal analysis the structural mass damping and stiffnes matrices of the model are determined by identification procedures. The stability boundaries, i.e. the critical flow velocity for the flutter instability of the model were measured in the wind tunnel.
