Design and Development of an Hybrid Strut-Based Lattice Structure
摘要
Lattices are cellular structures made of beams, surfaces, or plates that fit together in an ordered or stochastic manner and are frequently derived from nature. They feature a high strength-to-weight ratio and great energy absorption capacity. Hybridization is the modification of geometries of unit cells to achieve specific characteristics and increase stiffness. In this study, body-centered cubic (BCC) lattice geometry is used to hybridize by adding struts to different faces and edges. Simple BCC, BCC-hexagonal, and BCC-diamond lattices were designed in modeling software. Fused deposition modeling (FDM) is utilized to manufacture the final lattice models, and this study seeks insight into energy absorbing capabilities of lattices. Under quasi-static stress, the BCC-hexagonal lattice absorbs (7.152 J/mm3) the greatest energy, making it a prime contender for high-performance lattice designs when compared to BCC-diamond (4.073 J/mm3) and simple BCC (0.97 J/mm3). The current study’s findings show that the lattice structures geometry and capacity of energy absorption are strongly correlated.
