基于形式概念分析的3D零件结构模型关键结构确定方法
A Method to Find Critical Parts Structure of 3D Structural Model Based on Formal Concept Analysis
摘要
Abstract
Existing part’s coding method based on the assembly structural model was to search all structural codes and compare all codes in part retrieval.It reduced the retrieval efficiency.To solve this problem,a method to find critical structures of the parts based on formal concept analysis was pro-posed.By mapping relationships among the part functional surfaces and the positions to the binary for-mal context,a concept lattice of 3D parts structural model was built.Weights were designed by the in-formation entropy,the important attributes and the intents were found,then the formal concepts were sorted.The users can set thresholds as well as the deviation with the central weights to determine crit-ical structure of the parts.It lays the basis for the efficient parts query using structure coding.关键词
