Firearm variant design method supporting rapid generation of schemes

Abstract

The invention provides a firearm variant design method supporting rapid generation of schemes, comprising the following specific process of: a step 1, establishing a rule knowledge base and a design example base; a step 2, traversing the design example base according to new design requirements, calculating a requirement similarity between the new design requirements and each design example, and sending back a similar example set composed of a set number of examples of which the similarity is higher than a similarity threshold value; a step 3, performing adaptive modification on design parameters of each example in the similar example set according to design rules stored in the rule knowledge base, and obtaining a set of firearm schemes meeting the new design requirements; a step 4, evaluating the schemes in the scheme set obtained in the step 3 through a grey correlation method, and selecting the scheme with the best evaluation effect as a final variant design scheme. In the method provided by the invention, design knowledge and design experience, which are common in a design process, are embedded in the design process in the form of rules, thus, automation level of design activities is improved, and rapid acquisition of the design schemes may be realized.

Description

technical field [0001] The invention belongs to the technical field of product design, and in particular relates to a firearm variant design method that supports rapid generation of schemes. Background technique [0002] The research and development process of firearms products requires a long cycle and huge financial and material support. The design process involves cross-field and multidisciplinary knowledge support such as product function decomposition, component modeling, structure and performance optimization. A large amount of design work requires Refer to design knowledge such as design manuals, standard specifications, past product examples, and experience knowledge. Although systems such as product data management can provide life cycle information management for products, effectively organize all process information and resources related to products, and provide data management and control environments for product development and development, this is not enough fo...

Problems solved by technology

[0008] The purpose of the present invention is to improve the traditional firearm scheme design, in order to solve the problem that in the scheme design stage of firearm variant design activities, design knowledge and design process are separated from each other, design examples cannot be quickly reused in the design process, and design rules cannot directly constrain design behavior. , a firearm variant design method that supports the rapid generation of schemes is proposed
