摘要

对现有的猫中耳有限元模型进行了修改，加入了包含镫骨关节的壳表示。结果表明，随着关节柔韧性的增强，关节的面外和面内位移都变小。平面内旋转在所有刚度值下都保持显著，倾斜在大小和方向上作为刚度的函数变化很大。

On the effects of incudostapedial joint flexibility in a finite-element model of the cat middle ear

An existing finite-element model of the cat middle ear was modified to include a shell representation of the incudostapedial joint. Joint stiffness was varied from very small to very large and the results show that both out-of-plane and in-plane displacements become smaller as the joint becomes more flexible. In-plane rotations remain significant at all stiffness values and tilting varies considerably in magnitude and direction as a function of stiffness.
