Mathematical model of the support of experimental aerodynamical profile
Kozánek, Jan ; Bula, Vítězslav ; Zolotarev, Igor
In this paper the simple mathematical model of longitudinal and angular vibrating motion of experimental aerodynamical NACA0015 profile is given. With the help of dynamical experiments from complex frequency responses are by least squares fitting method identified complex eigenvalues. The direct identification method defines real coefficient matrices (of order 2) of stiffness, damping and mass of this non-conservative dynamical system. Finally, the comparisons of measured and from mathematical model evaluated responses are given and discussed.
