Abstract: [eng] [eng]
Byl vyvinut aeroelastický model kmitání lidských hlasivek postihující podmínky pro vznik fonace. Tzv. práh fonace je model vznikem aeroelastické nestability typu divergence nebo flutteru. Numerické výpočty byly prováděny na modelech lišících se tvarem matice tuhosti. Původní lineární teorie, která byla omezena na malé výchylky hlasivky, byla rozšířena tak, že jsou respektovány i nelineární složky aerodynamických sil. Linear two degrees of freedom aeroelastic system for modelling vibrations of human vocal folds was originally developed by which the physiological conditions for so-called phonation thresholds were modelled. The thresholds are given by aeroelastic instabilities of divergence or flutter type. Afterwards the model was generalised taking into account the non-linear aerodynamic terms, important for small glottal openings and large vibration amplitudes.
