stapes footplate

基本解释

The finite element model is used to analyze the displacement change of tympanic membrane and stapes footplate.
利用人耳有限元数值模型研究了鼓膜置管对鼓膜及镫骨底板振动的影响，分析了置管自身振动情况。
Result Amplitude variation laws of the stapes footplate and umbo were obtained by comparing the frequency response analytic results between the normal ear and pathological ear.
结果利用人耳数值模型进行正常耳和病变耳的谐响应分析，得到正常耳和病变耳镫骨底板和鼓膜凸的振幅变化规律。
Results: The results showed that the effusion of the middle ear decrease the amplitude of stapes footplate and umbo, weaken the incoming energy of the inner ear, thus leading to hearing loss.
结果：中耳积液导致鼓膜凸和镫骨底板的振幅减少，使得传入内耳的能量减弱，导致听力损失。

镫骨底板
Finally,a further research by changing the physical parameters of equivalent model was then made to observe the effect of lymph fluid on the sound transmission. The vibration motions of stapes footplate were also observed.
最后,本文通过进一步改变内耳淋巴液等效模型的物理参数,考察了内耳淋巴液对中耳声传导力学机理的影响;并通过有限元模型分析了镫骨底板的固有运动模式,为进一步研究内耳的力学机理提供了依据。
