Abstract: The lattice structure is a porous periodic structure which has the advantages of light weight, high specific strength, high impact resistance, vibration reduction, noise reduction. Meanwhile, the lattice structure has broad application prospects in aerospace, transportation, and other fields. This paper takes the pyramid lattice cylinder structure as the object, The parametric model is determined by independent structural parameters such as width, height and number of arrays, etc. and commercial finite element software was used to calculate the axial vibration characteristics of lattice structure. The influence of key parameters such as cell width, cell height and rod diameter on the damping effect was studied by the dimensionless parameters of normalized frequency and relative bandwidth. Through parameter analysis, a pyramid lattice cylinder structure with low frequency and broadband vibration damping performance has been designed. Then a sample is made by additive manufacturing. The vibration test results show that the experimental results are consistent with the finite element simulation. In the range of 500 Hz to 1500 Hz, the structure shows obvious vibration reduction effect, and the average attenuation strength reaches about 50 dB.
