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...

Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and specific examples. A firearm variant design method that supports rapid generation of schemes, the basic implementation process is as follows:

[0023] In order to apply the method of case-based reasoning to the field of firearm scheme design, figure 1 A rapid design process of firearms scheme based on case-by-case reasoning is constructed.

[0024] Step 1: Construct two knowledge bases, the design case base and the rule knowledge base.

[0025] The design example library stores the design examples of previous design activities. The content of the design examples includes three parts: (1) Design requirements information: the requirements of previous design activities, and a detailed description of the design problems. This part of the description information is the second step. The main object of instance similarity calculation usually exists in the form of tactica...
