Man-machine hybrid enhanced aircraft structural member design method based on instance reasoning

Abstract

The invention provides a man-machine hybrid enhanced aircraft structural member design method based on instance reasoning, which comprises the following steps: step 1, according to structural member design requirements, designers clearly design the type and other information of a target part; 2, after the information input in the step 1 is received, a computer conducts reasoning matching of similar cases in an instance library, and according to an instance reasoning algorithm, a similarity value is output; and 3, calling out examples with certain similarity deduced by a computer from the example library, directly using the examples if the examples directly meet the requirements, otherwise, performing deformation design by a designer according to the requirements, finally outputting parts meeting the requirements, and adding the parts into the example library to add more reference applications for subsequent example reasoning. The workload of designers can be reduced, and the design period is shortened. In actual detection, the modeling time can be saved by more than 80% under the same workload.

Description

technical field [0001] The invention belongs to the field of computer-aided design of aircraft structural parts, and particularly relates to a human-machine hybrid enhanced aircraft structural part design method based on case-based reasoning. Background technique [0002] With the development of the aviation industry, my country has put forward higher requirements for the design quality and design efficiency of aircraft structural parts. In the process of product development, new technologies such as computer-aided design are inevitably used to shorten the development cycle, thereby reducing costs and enhancing Competitiveness. [0003] China's aviation industry is at a critical stage of overtaking with the world's aviation powerhouse, and shortening the development cycle of aircraft is an inevitable choice in this process. There are many similar parts on the aircraft structure. When such similar parts are modeled by CATIA software, the steps and processes are exactly the sa...
