在人体声带生理与病理研究中，针对声带的难以侵入性的问题，从声带的解剖结构和发声机理出发，建立了人体声带的振动模型。基于真实人体喉部扫描得到的磁共振图像，使用图像处理软件对声带与声门气管图像进行分割处理，得到声带外形轮廓，然后通过黏稠性理论，建立声带“质量-弹簧-阻尼”的物理模型，最后利用有限元模态分析后发现，振动模型的弹簧与质量块在特定参数组合下能够模拟出相同基频的声带振动，证明了模型的合理性。

Inthestudyofphysiologyandpathologyofhumanvocalcords,inviewofthedifficult problems to invasive vocal cords,a new model of vibration is proposed,which is starting from the ana-tomical structure and vocal mechanism of vocal cord.Firstly use Mimics to segment the MR images of real human laryngeal and get the vocal silhouette,then set up a physical model call “weight-spring-damper”based on viscosity theory.The finite element analysis finally found that,the spring and mass of Vibration model can simulate the same fundamental frequency of the vocal cord vibration when under certain combi-nations of parameters,it also proves the rationality of the model.
