Simulation of vibration of the human vocal folds
Original language description
Three-dimensional (3D) finite element (FE) fully parametric model of the human larynx was developed and used for numerical simulation of stresses during 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. First, the basic frequency-modal properties of the model are presented for a given pre-stress of the vocal folds. Then 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 vocal fold tissue are computed in time domain. The results show significant dynamic stresses in all there directions (horizontal, vertical and anterior-posterior) and similar maxima of stresses were obtained for closed and open phase of the vocal folds motion.
