Problems solved by technology

[0003] Patent technology A method and system for engine modular fan design (CN202010885458.5) discloses a method of matching parts in the form of features, but the configuration BOM of this method is only for feature association of parts, but does not associate The features are constrained, so that when selecting the parts list through the features, not only need to check all the features, but also need to manually check the accuracy of the configuration

Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the specific embodiments and with reference to the accompanying drawings. It should be emphasized that the following description is exemplary only, and is not intended to limit the scope of the invention and its application.

[0024] With reference to the following figures, non-limiting and non-exclusive embodiments will be described.

[0025] like figure 1 A method for matching part feature constraint relationship shown in the figure, all the part features that form a part A are recorded as part group Y; each part feature corresponds to a specific part one-to-one; the correlation of each part feature in part group Y is The properties are related through constraint relationships; when one of the part features of component A is checked and recorded as key part feature B, the available part features applicable to the key part feature B are identified according to the constraint relationsh...

Abstract

The invention discloses a part feature constraint relation matching method. The method comprises the following steps: forming all part features of a part A and recording the part features as a part group Y; the part features are in one-to-one correspondence with specific parts; correlating the relevance of each part feature in the part group Y through a constraint relation; when one part feature of the part A is checked and recorded as a key part feature B, an available part feature applicable to the key part feature B is identified according to the constraint relation; the needed available part characteristics are automatically or manually selected; the checked available part features and the key part features form a part list of the part A, and the part A is obtained according to part assembly in the part list. The method has the advantages of being clear and convenient in part matching, reducing workload of operators and the like.

Description

technical field [0001] The invention relates to the technical field of engine parts matching, in particular to a method and system for matching a feature constraint relationship of parts. Background technique [0002] BOM (Bill of material, Bill of Materials) is a technical document that defines a manufacturing enterprise's products and their constituent materials. Generally, the products and the materials that make up the product are based on a table or tree diagram formed by the hierarchical relationship and quantity relationship between manufacturing and assembly. express. The material in the BOM has a broad meaning. It is a general term for production-related substances such as products, semi-finished products, work-in-progress, raw materials, accessories, cooperative parts, and consumables in a manufacturing enterprise. [0003] Patent technology A design method and system for an engine modular fan (CN202010885458.5) discloses a method for selecting parts in the form o...
