Abstract

The invention discloses a node enhanced lattice structure. The node enhanced lattice structure comprises a plurality of periodically repeatedly-arranged lattice single cells; the lattice single cellscomprise a plurality of spherical nodes which are distributed in a spatial manner and a rod body connected between the spherical nodes. According to the node enhanced lattice structure, spherical nodes are applied to an existing lattice structure, different rods are connected through rounded corners, so that smooth transition of the rod structure is realized, and the mechanical property of the lattice structure is improved.

Description

Technical field [0001] The invention relates to the technical field of material structures, in particular to a lattice structure. The lattice structure includes a plurality of periodically repeating units, and with its light weight, high strength, and open hole characteristics, it exhibits excellent mechanics and other functional properties. Background technique [0002] At present, with the rapid development of my country's aerospace and vehicles, the demand for lightweight design is becoming stronger. Under the premise of ensuring performance and safety, lightweight design can effectively save fuel and is an effective way to improve travel. The lattice structure is composed of periodic regular unit cells, with high specific strength, specific stiffness, low relative density and some special functions (such as damping and shock absorption, energy shock absorption). The application of lattice structure to aerospace, automotive and other fields has great potential. For example,...
