Research on mechanical properties analysis of new honeycomb sandwich structure
Honeycomb sandwich structure is widely used in modern industry.With the increasing demand for material structure in industry,it is urgent to innovate new honeycomb materials with high performance.In this paper,a new four-hole shape honeycomb structure was designed.Based on the wall thickness and overall size of a single cellular structure,the thickness of the honeycomb sandwich structure and cell combination,the mechanical properties of the structure under different directions were studied.The new four-hole shape honeycomb sandwich structure had better mechanical properties than hexagonal and octagonal honeycomb structures.The simulation results showed that compared to the hexagonal and octagonal honeycomb structures,the external force bearing capacity of the new four-hole shape honeycomb structure was significantly improved as well as the transverse and longitudinal isotropy.The new four-hole shape honeycomb structure is of great significance to functional material shape and structure in the field of aerospace,shipbuilding,automobile and other industries.
