Abstract

In order to control the low-frequency noise in the cabin of high-speed flying train, a flexible acoustic metamaterial based on Helmholtz resonance effect is proposed. Theoretical analysis was conducted on the noise reduction mechanism of the Helmholtz cavity, and the noise reduction characteristics of the unit cavity structure and array cavity structure were compared and analyzed using COMSOL software. The acoustic performance of flexible metamaterial was analyzed through the acoustic structure coupling module. The variation of the resonant frequency of the flexible acoustic metamaterial is studied parametrically, and analyzed the noise reduction characteristics of flexible acoustic metamaterials under different degrees of deformation. The casting process of divided draft was proposed to prepare flexible acoustic metamaterial samples, and the transfer loss of samples was measured using the four sensor testing principle. The research results show that there is a transmission loss peak at 300Hz in the test and simulation results of flexible acoustic Metamaterial, which shows the Helmholtz resonance frequency lower than the theoretical model and good low-frequency noise control effect. At the same time, flexible materials can avoid the impact of inertia on the installation environment, which is suitable for curved surface environment, and has good application prospects in the engineering field.
