Abstract

The invention provides a method for realizing specific honeycomb structure strength, which comprises the following steps of: establishing a simulation model of a honeycomb material by utilizing simulation software, and realizing the specific honeycomb structure strength by adjusting material performance parameters and / or honeycomb hole lattice size parameters of the simulation model. According tothe invention, the simulation model of the honeycomb material is established in the computer by means of simulation software. Various parameters of the simulation model are adjusted quickly; the specific honeycomb structure strength is accurately obtained. The problem that the strength period of a specific honeycomb structure obtained by utilizing an empirical method and a semi-empirical formula theory method is long is effectively solved. The precision is low, and the repeatability is poor. The honeycomb structure strength adjusting repeatability is improved, honeycomb materials in actual production finished products can be reversely simulated according to the specific honeycomb structure strength required by customers, then honeycomb hole lattice size parameters required by honeycomb material production are rapidly and accurately obtained, and the production efficiency of the honeycomb materials is improved.

Description

technical field [0001] The invention belongs to the technical field of honeycomb material manufacturing, and more specifically relates to a method for realizing specific honeycomb structure strength. Background technique [0002] Honeycomb material is a composite material with a honeycomb structure, and its honeycomb structure generally consists of a series of hexagonal, quadrilateral or other shapes of honeycomb-like cells. Because the honeycomb structure has higher strength and stiffness than other forms of sandwich structures, and has a lower elastic modulus and higher energy absorption performance, it is widely used in passive safety in aerospace, aviation, rail transportation and other fields. in protective gear. [0003] The axial compressive strength is one of the important mechanical performance parameters of the honeycomb structure, which determines the energy absorption capacity of the honeycomb material under the same area. However, due to the different mechanic...
