Numerical simulation of self-oscillations of human vocal folds based on aeroelastic theory

Abstract eng:
Linear two degrees of freedom aero-elastic 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 aero-elastic 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. Now, after adding the Hertz's contact model for the impacts of the vocal folds into the developed aero-elastic model a complete numerical simulation of self-oscillations of the vocal folds during phonation is made possible.
