| 摘 要： | 研究声带振动模型对揭示声带振动特性及理解声带振动的生理病理特征具有重要意义。本文结合非对称二质量块模型和有限元模型的优点,建立了声带振动的二质量块-有限元模型,并利用该模型实现了高速声门图的仿真。仿真结果表明,无论是正常声带的振动状态还是病理振动状态,输出结果都和实际声带振动特性相吻合。该模型为全面理解声带振动特性提供了一个崭新的工具

| Abstract: | Modeling vocal-fold vibration is extremely significant in realizing th e vibration properties of human vocal folds and investigating their physiologi ca l and pathological characteristics. A combined model presented is two mass-fini t e element (T-F) model, which integrates all merits of both the finite element m e thod (FEM) model and the asymmetric two-mass model of vocal folds. The high-sp ee d glottis graph (HGG) can also be synthesized by the model. The result shows tha t T-F model can simulate the vibration behavior of normal and pathological voca l folds in a more realistic way with competitively computational speed. Therefore , the T-F model is helpful to gaining a thorough understanding of the vibration properties of vocal folds. |
