Abstract: 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.
Key words: part features, complex networks, changes propagation, change impact, product research and development
摘要: 针对零部件特征划分组合不唯一的问题,提出“三维实体+2D特征+连接关系”表达的零件特征划分方法;定义了特征之间的强弱连接关系,并构造了产品特征网络模型。基于特征强弱连接网络模型,定义了特征节点的3种离散状态,给出了变更传播指数的含义,分析了产品特征变更传播的两种类型及其概率计算方法,并对产品特征网络变更影响程度进行了评估。通过某航天产品的阀体的特征网络构建及其变更实例分析,验证了所提评估模型的可行性。
