Embodiment Construction

[0045] A method for checking integrity of MBD data sets based on association rules in the present invention, such as Figure 6 As shown, the specific steps of the method are as follows:

[0046] Step 1: If figure 1 As shown, the design, manufacturing, testing, management and other information that needs to be defined in the MBD data set in the enterprise are decomposed in detail, and all items are uniquely coded and managed and released by the computer. Each of these entries is called a piece of standard engineering annotation information, and also constitutes each item in the association rule. Each standard engineering comment is composed of "code" + "label content" + "URL", where URL is a detailed document of the standard engineering comment, such as "5SN00796|Provide the tensile modulus and tensile strength data of the furnace test piece| http: / / standards.web.CASC.com / hlgw.cgi?app=BAC&spec.”

[0047] Step 2: Record the construction history of the MBD data set, store the ...

Abstract

A method for checking the integrity of MBD data sets based on association rules, the steps are as follows: 1. Decompose the design, manufacturing, testing, and management information that needs to be defined in the MBD data set, encode all items, and manage and publish them by computer ; 2. Record the definition history of the MBD dataset; 3. Clean the data in the history; 4. Use the association rule algorithm to mine the historical records of the MBD dataset; 5. Import all frequent item sets into frequent sets In the database, import the association relationship and its confidence value into the relational database; 6. Obtain all the standard engineering annotations of the MBD data set that need to be inspected for integrity, and extract the strong association item set Ck that contains the most items; 7. Query the rule Confidence degree of the rule and sorted; 8. Query the confidence degree of the rule and sort it. The invention standardizes non-geometric information and performs unified coding management, has high accuracy and good adaptability.

Description

technical field [0001] The invention relates to a method for checking the integrity of a data set based on model definition (MBD), in particular to a method for checking the integrity of an MBD data set based on association rules, which can check the integrity of non-geometric information in an MBD data set through association rules , to meet the design definition requirements, belonging to the field of computer-aided design. Background technique [0002] In the past 20 years, with the continuous improvement of the level of digital technology, the large-scale equipment manufacturing industry represented by aerospace has gradually adopted the full three-dimensional digital quantity and size transmission system. Boeing fully adopted the MBD (Model Based Definition) technology integrates 3D product design information and 3D manufacturing information into the product 3D model, cancels 2D drawings, and realizes high integration of product design, process, tooling, part processing...
