Abstract Construct a negative Poisson's ratio metamaterial composed of hexagonal honeycomb cells and use it as a connection structure between double-layer plates. Based on the finite element method and the boundary element method, the sound and vibration analysis of the double-layer plate structure with negative Poisson's ratio metamaterial ribs is carried out. The geometric characteristics and mechanical properties of the negative Poisson’s ratio cell of the hexagonal honeycomb are analyzed, the double-layer plate with negative Poisson’s ratio ribs is designed and the vibration is solved, and the influence of the cell filling damping on the vibration is analyzed. The results show that the response of the lower panel of the double-layer board is significantly attenuated compared to the upper panel. The total mass of the control structure remains unchanged. By adjusting the width and thickness of the negative Poisson's ratio ribs, the equivalent modulus of the cell is changed, and then the rib stiffness is changed, and vibration and radiation noise calculations are performed. The results show that compared with the double-layer panel connected by the flat panel, the double-layer panel with negative Poisson's ratio ribs has a good absorption and attenuation function for vibration energy, and can better reduce the panel's vibration response and radiated noise; The smaller the thickness of the negative Poisson's ratio ribs, the lower the equivalent modulus of the interlayer structure, and the lower the vibration and radiated sound power.
