Abstract

The invention provides a part searching method and system, and relates to the technical field of computer technology. According to the method, part feature information (including geometric structures, material attributes, machining process information and the like) is converted into feature vectors through an algorithm model. The method comprises the following steps: firstly, training a historical part feature information conversion algorithm model; 2, storing a trained model and historical part feature vectors, and constructing a historical feature vector library; 3, inputting feature information of a to-be-searched part to the trained model to obtain a feature vector; 4, calculating the similarity between the feature vector of the to-be-searched part and all parts in the historical part feature vector library; and 5, determining and outputting a search result. The technical problem that in the prior art, the accuracy of part retrieval is low is solved.

Description

technical field [0001] The invention relates to the technical field of computer technology, in particular to a search method and system for parts. Background technique [0002] In the product development process of the mechanical design industry, there are a large number of repetitive designs (that is, reuse of past component designs), while completely new designs only account for a small part. Therefore, it is one of the keys to improve design efficiency and shorten the development cycle to search for similar part models from the database and modify them simply, quickly and accurately. [0003] The traditional part search method is to mark each part in advance by the designer, add some index information, divide it into different categories, and then achieve the part index through keyword search. [0004] Due to the traditional method: the designer needs to mark all the parts, and the new parts designed in the follow-up also need to perform this operation, which is a long-t...
