Numerical simulation of video-kymographics records of the vocal fold vibration
Original language description
The reconstruction of the video-kymographic records from the numerical simulation of the vocal fold vibration is used for modelling of vocal fold damage. Three-dimensional (3D) finite element (FE) fully parametric model of the human larynx was developedand used for numerical simulation of stresses in vibrating vocal folds with collisions. The complex model consists of the vocal folds, arytenoids, thyroid and cricoid cartilages. The vocal fold tissue is modeled as a three layered transversal isotropic material. The results of numerical simulation of the vocal folds oscillations excited by a prescribed intraglottal aerodynamic pressure are presented. The FE contact elements are used for modelling the vocal folds collisions and the stresses in the vocalfold tissue in time domain. A damage of the ligament tissue is simulated by the modification of the modulus of elasticity. The video-kymographic records are reconstructed for health and damaged vocal folds. The results show significant dy
