    摘要:

    目的采用有限元模拟,建立人耳蜗基底膜模型,研究耳蜗结构的动力响应。方法应用有限元方法,利用大型有限分析软件ANSYS求解基底膜简化模型的模态。结果 得到了模型上不同部位产生最大振幅时对应的振动频率。结论 频率不同时,行波传播的远近和最大行波的出现部位不同。振动频率愈低,最大行波振幅出现的部位愈靠近基底膜顶部;相反地,高频率声音引起的基底膜振动,只局限于卵圆窗附近。从一个新的角度验证了行波理论。

    Abstract:

    Objective The model of base membrane of human cochlea is founded with the finite element analysis(ANSYS), there is certain scope of travel wave and largest amplitude of vibration on the base membrane of human cochlea among every frequency, so that the dynamical response has been researched. Methods This paper discribe the model of human cochlea with the Finite Element which named ANSYS. Results The different frequency is obtained under different situation of the model and different position of human cochlea. Conclusion The different frequency sound cause travel waves from the bottom of the base membrane of human cochlea to the top of the base membrane of human cochlea. The lower vibration frequency is, the further the travel wave transfers, the largest travel wave appears near the top of the base membrane of human cochlea.
