N2 - The lattice sandwich structure manufactured by SLM technology has the characteristics of light weight, high strength, and high rigidity, which have received widespread attention in manufacturing industry, especially in the aerospace field. As one type of lattice sandwich structure, Thriply Periodic Minimal Surface (TPMS) has become a new solution for constructing lattice structures due to its smooth surface, highly connected porous structure and mathematically controllable geometric features. Vibration characteristics are an important indicator of dynamic properties and are crucial for engineering design and structural safety. Therefore, studying the inherent frequency of novel TPMS can guide the engineering design of lattice sandwich structures to achieve excellent dynamic performance. In this paper, four different configurations of TPMS sandwich specimens with G, P, D, IWP were prepared based on AlSi10Mg new material using SLM (Selective Laser Melting) technology along with typical FCC, BCC lattice sandwich specimens. The vibration characteristics of various TPMS configurations and multi-size triply periodic minimal surface core structures were studied through finite element simulation numerical methods combined with experimental verification. The results show that TPMS sandwich structures with good designability have better vibration characteristics compared to typical face-centered cubic or body-centered cubic lattice sandwich structures. This paper concludes that reasonable selection of TPMS configuration and relative density can enable this type of structure to obtain better shock absorption ability which will bring new ideas and inspirations for lightweight applications in related fields such as aviation and aerospace industries, weapons and equipment industries, and automotive industries etc.
