A finite-element model of the cat eardrum is presented which includes the effects of the three-dimensional curved conical shape of the drum. The model is valid at low frequencies (below 1-2 kHz) and within the range of linear vibration amplitudes. The material properties used are based on a review of the literature. The critical material parameters are the stiffness (2 times 10(8) dyn cm(-2)) and thickness (40 micrometer) of the pars tensa. The model exhibits a vibration pattern and amplitude very similar to those observed experimentally using laser holography. A number of parameters are varied in order to study their relative importance in the model.
本文提出了一种猫鼓膜的有限元模型，该模型考虑了鼓膜三维弯曲圆锥形状的影响。该模型在低频（低于1-2kHz）和线性振动幅度范围内有效。所使用的材料特性基于文献综述。关键材料参数是紧张部的刚度（2×10⁸达因/厘米²）和厚度（40微米）。该模型呈现出的振动模式和幅度与使用激光全息术进行实验观察到的非常相似。为了研究它们在模型中的相对重要性，对多个参数进行了变化。
