Abstract In this paper, based on the measured spectrum characteristics of the interior noise of the wheel-driven bus, the localized resonance mode was used to analyze the feasibility of the local resonance phononic crystal in low-frequency vibration reduction and noise reduction. The structural characteristics of the slab material, the band gap orientation of the phononic crystal was controlled by changing the material composition (scatterer density, elastic modulus of the cladding layer) and structural components (inter-filling ratio between the components), and the material structure of the phononic crystal plate material conforming to the vibration and noise characteristics of the wheel-driven bus wasobtained. The above analysis method provides a feasible reference for the application research of two-dimensional local resonance phononic crystal on the vibration and noise reduction of the wheel-driven bus.
