The flow-induced vibration of synthetic vocal fold models has been previously observed to be acoustically-coupled with upstream flow supply tubes. This phenomenon was investigated using a finite element model that included flow-structure-acoustic interactions. The length of the upstream duct was varied to explore the coupling between model vibration and subglottal acoustics. Incompressible and slightly compressible flow models were tested. The slightly compressible model exhibited acoustic coupling between fluid and solid domains in a manner consistent with experimental observations, whereas the incompressible model did not, showing the slightly compressible approach to be suitable for simulating acoustically-coupled vocal fold model flow-induced vibration.

计算声带模型的声耦合流致振动

先前已经观察到合成声带模型的流动引起的振动与上游流动供应管在声学上耦合。使用包括流-结构-声相互作用的有限元模型研究了这种现象。改变上游管道的长度以探索模型振动和声门下声学之间的耦合。测试了不可压缩和轻微可压缩的流动模型。微可压缩模型以与实验观察一致的方式表现出流体域和固体域之间的声耦合，而不可压缩模型则没有，表明微可压缩方法适用于模拟声耦合声带模型流动引起的振动。
