摘要

摘要利用充液圆柱壳的解析模型分析了四分之一波长吸收体中的波传播。已经发现，由于强的流体-结构相互作用，使用柔顺壳体可以达到相当大的波速降低。因此，通过参数研究，评估吸收器的尺寸，以达到更高效和紧凑的设计。此外，柔性材料的使用允许将流体处理为不可压缩的，这有助于简化计算。

Wave Coupling Analysis in the Elastic Waveguides of Quarter Wavelength Noise Absorbers

Abstract The analytical model of a fluid filled cylindrical shell is used to analyse the wave propagation in the quarter wavelength absorbers. It has been found, that due to the strong fluid-structure interaction, the considerable wave speed reduction can be reached using a compliant shell. Thus via parametric studies, the dimensions of the absorbers are assessed to reach more efficient and compact design. Furthermore, the use of the compliant materials allows treating the fluid to be incompressible, which helps to simplify the calculations.
