| 摘 要： | 基于有限元法和模态分析的基本理论，利用有限元分析软件ANSYS建立了钢琴音板的有限元模型．然后对钢琴音板进行模态分析，得到了它们的固有频率、模态振型等参数，分析了树种对于钢琴音板基频的影响。结果表明：不同的树种对钢琴音板基频的影响是明显可见的，在所研究的几个常用树种中，轻木音板的基频最大．而核桃木音板基频最小。

| Abstract: | Based on the theory of finite element method and modal analysis, the model of a piano soundboard is established in the ANSYS, then the models＇ natural frequency, mode shape are calculated. What is more, the influence of tree species on the piano soundboard＇s fundamental frequency is discussed. The result shows that the influence of tree species on the fundamental frequency of a soundboard is obvious. Among several tree species studied, the fundamental frequency of a ochroma lagopus soundboard is the highest, and that of a walnut soundboard is the lowest. |
