Abstract

The invention discloses a processing method of an octahedral lattice structure and a derivative topological configuration lattice structure of the octahedral lattice structure. The processing method comprises the following steps that an in-plane truss and an out-of-plane truss are manufactured, the in-plane truss and the out-of-plane truss are assembled in an embedded mode through a bayonet embedding method, an 'octahedral core-octahedron' multi-layer configuration lattice structure is assembled, and an 'octahedral core-octahedral core' multi-layer configuration lattice structure is assembled.The designed 'octahedral core-octahedron' multi-layer configuration light lattice structure and the derivative lattice structure thereof have the high specific strength, the high specific stiffness and the high energy absorption property, in addition, the 'octahedral core-octahedron' multi-layer configuration lattice structure and the derivative octahedral base lattice structure thereof can alsobe widely applied to the civilian field, severs as a novel building plate and decoration / ornament plate, and used as structural load-bearing parts in the building filed, furniture and home building materials and decoration consumables, the specific stiffness and the specific strength of final products can be improved, and meanwhile, the demands of a user for product attractiveness can further be met.

Description

technical field [0001] The present invention relates to the processing method of octahedral lattice structure and its derived topological configuration lattice structure, specifically refers to a kind of cheap subtractive processing method to prepare "octahedral core-octahedron" multi-layer configuration lattice structure and its Derived topological configuration lattice structure. Background technique [0002] The strong demand for structural weight reduction is mainly due to energy considerations; for example, the US military's fuel consumption in military vehicle and ship transportation reaches 1 million US dollars per day. The data show that every 10% reduction in weight of the vehicle and ship structure can reduce fuel consumption by 10% to 15%. At the same time, the strong demand for structural weight reduction is also due to the requirements for improving the performance of military vehicles and ships in terms of maneuverability, mobility, speed, and stability.

Problems solved by technology

However, there is currently a lack of advanced engineering preparation methods to fabricate lattice structures with complex topological configurations.

[0003] Traditional engineering methods for preparing lattice structures are limited to fusion casting and additive manufacturing. However, these methods are costly and complex, and there are defects such as pores in the matrix material, which reduces the intrinsic mechanical properties of the matrix material; rough The surface constitutes a source of fatigue; the size of the product is limited, and scalable production cannot be obtained; in addition, the selectivity of the matrix material is limited, limited to specific metals and resins, and cannot be applied to many high-performance metals, ceramics and composite materials

In order to solve the limitations of the above-mentioned traditional preparation methods, the design and development of novel engineering preparation methods to manufacture lattice structures has become an urgent problem to be solved
