【Abstract】 A method of establishing dynamic model for a human-like middle ear ossicular chain system and motion simulation analysis using Adams is proposed.The motion characteristics of the ossicular chain of the middle ear were simulated and studied by establishing a three-dimensional model of the ear ossicles of the middle ear.The spring was used to simulate the ligament function and determine the corresponding physical parameters to study the vibration reduction effect of the ossicular chain system. Research on the dynamic characteristics of the model,through the dynamic simulation analysis of the three-dimensional model of ossicular chain system,the displacement simulation results of the malleus and the stapes footplate were extracted and compared with the experimental data,which confirmed the reliability of the three-dimensional model.The established middle ear model can simulate the sound transmission function of the middle ear to some extent,can predict the mechanical characteristics of middle ear sound transmission,and has certain reference significance for the study of the vibration damping characteristics of middle ear ossicular chain system.更多还原
