Method of low-frequency vibration isolation component with multicell interlacing triply periodic minimal surface lattice metamaterials and vibration isolator

A design method of a low-frequency vibration isolation component with a multicell interlacing triply periodic minimal surface lattice metamaterial, comprising:

• in step S1, determining a cell topology type and interlacing-cell number of the required triply periodic minimal surface lattice metamaterial, wherein the cell topology type comprises a Gyroid triply periodic minimal surface structure, an IWP triply periodic minimal surface structure, and a Diamond triply periodic minimal surface structure;
• in step S2, constructing a corresponding normal triply periodic minimal surface three-dimensional model based on the cell topology type, and based on the interlacing-cell number, replicating the normal triply periodic minimal surface three-dimensional model with a corresponding interlacing-cell number along a preset direction at a preset spacing to obtain a multicell interlacing triply periodic minimal surface three-dimensional model, wherein the preset spacing is less than a side length of a corresponding cell structure;
• in step S3, removing structures that are not interlacing at edges of the multicell interlacing triply periodic minimal surface three-dimensional model;
• In step S4, constructing a bottom plate with a preset thickness on a pair of side surfaces of the multicell interlacing triply periodic minimal surface three-dimensional model with redundant structures removed to obtain a low-frequency vibration isolation component model.
