The Study Of Mechanical Properties And Processing And Forming Technology Of Cubic Cellular Metal Material

In this paper, the mechanical properties and manufacturing process for the cellular material with cubic structure are studied. The cellular metal material is a hollow cube cubic unit cell structure based cellular material. According to the functional requirements and the geometric characteristics of the cubic unit cell cellular material prepared spatially arranged to form a cellular material having a specific function and shape.Special attribute structure of the cellular material is its internal disperse a large number of holes, compared with conventional solid material which has a lot of special properties, this study mainly for their mechanical properties, combined with the finite element simulation method, its static depth analysis of mechanics and dynamics. Statics, mainly for the cellular metal cubes through DoE analysis, design statics simulation, analysis of static mechanical properties of the cellular material of different material size parameters under positive pressure, and the relative density of the cellular metal studied. Dynamics, finite element simulation and theoretical structural honeycomb material quadrilateral and its dynamics calculations, research cubic cellular metal material with respect to the mechanical properties of the cellular material quadrilateral comparative analysis.This paper presents a method for sheet metal stamping process, the process for preparing a cellular metal cube. Cube split by a combination process, the cubic unit cell is divided into two separate cubes split. Each cube split by a set of progressive stamping, respectively, the two units split snap together to form a complete cube monomer. Then a lot of cube unit body by a metal bonding or laser welding process, spliced into a complete cube cellular metal samples. Through experiments at room temperature, the cellular metal test sample preparation process for the completion of the analysis.
