Assembly Model Retrieval Based on Attributed Relational Graph Matching

In this paper, an assembly model retrieval method based on attributed relational graph matching is presented in order to find the similar assembly model for design reuse and generation of manufacturing and assembly plans.First, the contact faces' attributes are extracted from the assembly model, meanwhile the assembly model and its parts models are respectively described as part attributed relational graph and contact face attributed relational graph.Then, the matching number of the faces and their relation and the parts' compatibility matrix are calculated, which serves as the respective measure of the similarity between two parts and between two assemblies.Finally, the optimal matching with the measures is calculated using Kuhn-Munkres algorithm.Experimental results show that the method is able to support the assembly model retrieval.
