Abstract

The invention provides a method for calculating double reinforced regular hexagon honeycomb axial compressive stress. The method comprises the following steps of: step1, based on a geometrical configuration of a double reinforced regular hexagon honeycomb, calculating total bending deformation energy absorbed by four additional plane units; step 2, calculating total thin film deformation energy absorbed by four additional plane units; step 3, based on energy conservation, according to the total bending deformation energy and total thin film deformation energy obtained in the above steps, calculating axial compressive stress of the double reinforced regular hexagon honeycomb under the axial compression. The method disclosed by the invention is not limited to predict the static mechanical properties and explain the deformation mechanism, and can calculate the axial compressive stress by using super-folded element theory based on the principle of conservation of energy. The calculation method has the advantages of simple analytical expression, high precision and high reliability and can rapidly judge energy absorption ability of the honeycomb energy-absorbing devices of different cell-element sizes.

Description

technical field [0001] The invention relates to the technical field of regular hexagons reinforced with double ribs, in particular to a method for calculating the axial compressive stress of a regular hexagonal honeycomb reinforced with double ribs. Background technique [0002] Because of its light weight and good energy absorption properties, honeycomb materials are often used to make various energy absorption or buffer devices, and are widely used in the fields of aerospace and vehicle engineering. Honeycomb materials can absorb a large amount of impact energy when subjected to axial impact. With the increasing application of honeycomb materials in protective structures, the research on the axial compression characteristics of honeycomb materials during impact has become one of the key issues in their performance design. [0003] The axial impact mechanical properties of honeycomb structure are closely related to its geometric configuration. In order to improve the ener...
