The study on human vestibular membranous labyrinth biomechanical model

To verify the feasibility of mechanical indentation instead of rotation to stimulate the same biological response of vestibular membranous labyrinth,the Lagrangian method was used to numerically simulate the fluid-structural interaction in the labyrinth when it was subjected to one of the above excitation.The results indicated that we could obtain the same biomechanical response to the two different stimulations of the excited semicircular canal when the rotation axis passed through sensory epithelial cells,while it was significantly different in the other semicircular canals.The study finally proves out that it is reliable to analyze the endolymph-equilibrium receptor system using the Lagrangian method,and it would provide a basis for in-depth study on the relationship between vestibular mechanics and human balance mechanism.
