鼓膜的力学特性对于研究耳部的声学传播是至关重要的。在这项研究中，我们研究了鼓膜在环境和中耳之间不匹配的气压下的褶皱行为。采用Rayleigh-Ritz方法分析了临界起皱压力和基本特征振型。得到了近似解析解，并用有限元分析进行了验证。该模型将在未来研究TM的褶皱变形如何改变耳朵的声传输功能方面发挥作用。
Mechanics of tympanic membrane (TM) is crucial for investigating the acoustic transmission through the ear. In this study, we studied the wrinkling behavior of tympanic membrane when it is exposed to mismatched air pressure between the ambient and the middle ear. The Rayleigh-Ritz method is adopted to analyze the critical wrinkling pressure and the fundamental eigenmode. An approximate analytical solution is obtained and validated by finite element analysis (FEA). The model will be useful in future investigations on how the wrinkling deformation of the TM alters the acoustic transmission function of the ear.
