Low-Frequency Acoustic Vibration Characteristics of Cylindrical Shells With Anisotropic Mechanical Material

Year: 2025

Type: article

Abstract: A precise acoustic vibration characteristic model of a cylindrical shell with anisotropic mechanical material was established based on three-dimensional elasticity theory and state space vector, and the accuracy of the analytical model was verified by comparing it with finite element results. By analogy with the concept of metamaterials, the modulus of the mechanical material is artificially changed to negative and complex numbers with extraordinary properties. Based on the acoustic vibration characteristic model, the influence of material parameters on the radiative noise transfer characteristics of anisotropic mechanical material cylindrical shells is studied.
