Establishment method for multi-dimensional tool design knowledge assembly

Abstract

The invention relates to an establishment method for a multi-dimensional tool design knowledge assembly and belongs to the field of knowledge engineering and digitization design. According to the method, from the aspects of the process dimension and object dimension in the tool design process, the multi-dimensional tool knowledge assembly is established, and tool design process knowledge is effectively organized, managed and used. Related design resources in the tool design fields such as design rule knowledge, parameterization and three-dimensional models are mainly involved. According to different types of knowledge, a structuralization method is adopted for organizing a rule, knowledge application in the knowledge assembly is definite, and the running mode of a specific design task is completed. According to the establishment method, the automated reasoning process of a decision is achieved, and human intervention in the tool design process is reduced. In the running process of theknowledge assembly, the running result of the knowledge assembly is directly determined through parameter values input by design personnel, the integrated process from an input requirement of a user to an output result is achieved, and the man-machine interaction part when the task is executed in the knowledge assembly is reduced.

Description

technical field [0001] The invention relates to a method for constructing multi-dimensional tooling design knowledge components, belonging to the fields of knowledge engineering and digital design. Background technique [0002] Due to the complex structure and function of tooling, tooling-related design knowledge has rich semantic connotations and complex and diverse constraint relationships. The concepts and relationships in the field of tooling design are complex and ambiguous. In order to realize the unique definition of tooling design domain knowledge in the whole tooling design process, in the current technology related to knowledge components, some knowledge ontologies established by Dong Mingming in "Research on the Construction Method of Knowledge Components Supporting Design Reuse" are relatively fragmented and have not been established. A set of procedural, systematic and automated system does not form a general, multi-dimensional knowledge organization method, can...

In order to realize the unique definition of tooling design domain knowledge in the whole tooling design process, in the current technology related to knowledge components, some knowledge ontologies established by Dong Mingming in "Research on the Construction Method of Knowledge Components Supporting Design Reuse" are relatively fragmented and have not been established. A set of procedural, systematic and automated system does not form a general, multi-dimensional knowledge organization method, cannot well integrate various knowledge forms in the process of tooling design, and cannot effectively realize tooling planning and design, structural design, etc. Knowledge reuse in the entire design process; Gao Bo did not well organize and express the tooling design subject (workpiece), design requirements (tooling body and examples) and tooling design process in the "Research on Rapid Design of Tooling Components Based on Knowledge Components" The knowledge needed; Liu, Rosen, and Yu gave an ontology-based knowledge modeling method in "Ontology based knowledge modeling and reuse approach inproduct redesign", which divides variant design activities into parametric variant design activities and structural variants Design activities, corresponding knowledge will be provided when performing different activities, but the detailed solution steps of the method and the method of constructing the ontology are not given; In "Research on Tooling Intelligent Design Technology", a tooling component knowledge component modeling method was proposed, and the knowledge component model was defined, but the structure of the knowledge component was not refined, and the expression of design knowledge was formulated in depth, considering how to integrate Knowledge is well organized and managed, and detailed actions for internal execution are not specified
