摘要：
Aiming at the problem that the feature division sets of parts and assembly is not unique, a part feature division method composed of "three-dimensional entity, 2D feature and connection relation" was put forward. The definitions of strong connection relation and weak connection relation among features were given, and the product feature network model was constructed. Based on the strong and weak link network model of complex product features, three discrete states of feature network nodes were defined and the meaning of change propagation index was given. Two types of change propagation probability and its calculation method were defined and the influence degree of change propagation of product feature network was evaluated. The feasibility of the proposed evaluation model was verified through the features network construction of a space product's valve body and the analysis of its change propagation. © 2019, Editorial Department of CIMS.
