This paper presents a three-dimensional finite-element model of the cat eardrum which includes inertial effects. The model is implemented using a hierarchical modeling scheme which permits the mesh resolution to be varied. The static behavior of the model is calculated as a function of mesh resolution in order to check the validity of an earlier model. The first six undamped natural frequencies, and the corresponding modal vibration patterns, are then calculated. They are found to lie between about 1.8 and 3.2 kHz for the standard values chosen for the model parameters. The effects on the natural frequencies of varying seven parameters of the model are described.
本文提出了一个包含惯性效应的猫鼓膜三维有限元模型。该模型采用分层建模方案实现，允许改变网格分辨率。计算模型的静态行为作为网格分辨率的函数，以检验早期模型的有效性。然后计算前六个无阻尼固有频率以及相应的模态振动模式。对于为模型参数选择的标准值，发现它们在约1.8至3.2千赫兹之间。描述了改变模型七个参数对固有频率的影响。
