Study of Vibro-Acoustic Coupling FEM for Predicting the Acoustical Property of Sandwich Composite

  • 摘要: 针对泡沫夹芯复合材料声学测试的实际情况,建立了耦合声学有限元法的计算模型,针对计算模型进行了算例验证。结果表明,模型的预测值与试验值趋势吻合较好,计算方法是有效且可行的,可以用于预测泡沫夹芯复合材料的声学性能。同时,研究了与面板和芯材有关的四个参数对夹芯复合材料声学性能的影响规律。
    Abstract: Considering the situation of acoustical test,we have established the model of the coupled acoustic FEM and verify of numerical example. The predicting result of numerical model is corresponding to the test result. Meanwhile,The method is efficient and right. the paper has done research on the influence of the four parameters related with the panel and the core material on the acoustic performance of sandwich composite.
