The invention discloses a honeycomb structure corrosion damage library construction method. The honeycomb structure corrosion damage library construction method comprises the following steps: step 1: classifying to-be-tested honeycomb structures to form multiple groups of to-be-modeled honeycomb structures; step 2: modeling each group of the to-be-modeled honeycomb structures; step 3: performing mesh division on each group of honeycomb structure models, wherein any mesh in any group of honeycomb structure models is called as a honeycomb structure unit; step 4: changing the thickness of each honeycomb structure unit to obtain multiple groups of honeycomb structure units with different thicknesses, wherein each of the honeycomb structure units with the different thicknesses is called as a to-be-tested group; step 5: stimulating each to-be-tested group to obtain different frequencies of to-be-tested groups; and step 6: summarizing frequency data of the honeycomb structure units with the different thicknesses to construct a honeycomb structure corrosion damage library. With the adoption of the method, the batch detection can be carried out.
Description
technical field [0001] The invention relates to the technical field of honeycomb structures, in particular to a method for constructing a corrosion damage library of a honeycomb structure. Background technique [0002] With the advancement of industry, the honeycomb structure is widely used in various fields of national production. Among them, in the field of aircraft design and manufacturing, the honeycomb structure has gained an increasingly important position. The use of honeycomb structure can improve structural efficiency and reduce structural weight. Followed by the health monitoring of the honeycomb structure, corrosion damage inspection, repair and other related issues. [0003] In the prior art, a corresponding physical inspection is usually performed for a certain honeycomb structure. In this way, when multiple honeycomb structures need to be inspected, it has the disadvantages of time-consuming and labor-intensive waste. [0004] Therefore, a technical solution...
