Abstract Because of its good impact resistance, large specific strength and high specific stiffness, grid sandwich panel is widely used in practical engineering.Although the grid sandwich panel structure has excellent sound insulation performance in high frequency band, its sound insulation performance is not ideal in medium and low frequency bands due to the limitation of the mass law.As a kind of periodic structure, phononic crystal has excellent noise suppression performance because of its special band gap characteristics to make elastic wave with specific frequency unable to propagate in a structure.Here, phononic crystal structure was combined with sandwich plate structure to design a kind of phononic crystal sandwich plate structure with excellent sound insulation performance in setting frequency range.Numerical simulation and structural model tests were performed to do verification.It was shown that the designed phononic crystal sandwich plate structure has excellent sound insulation performance.
