英文摘要	Cellular metal is an ideal energy absorbing material which is extensively used in passive safety area. This paper investigates the manufacturing process and mechanical properties of a novel periodic cellular metal with three-dimensional closed cubic structure. The manufacturing process of this kind of cellular metal is unconventional because it is obtained initially by sheetmetal forming, and then by cells bonding. In this work, two methods including gluing and laser welding are introduced for bonding the cells. By the gluing method, various cellular metalswith irregular/regular topological cellular structures can be automatically manufactured via an innovative device which is originally put forward in thiswork. By contrast, the laserweldingmethod ismore suitable for fabricating the cuboid cellular metal blocks. Meanwhile, the cellular metal fabricated by laser welding comparing with by adhesive owns better mechanical performance because there are not any heterogeneous layers between the cells. In order to investigate the mechanical properties of the cellular metal fabricated by laser welding, a series of quasi-static compressive and dropweight impact experiments were carried out. The experimental results demonstrate that the presented cellular metal possesses a sound energy absorbing performance and a great potential used for passive safety.
