Part semantic relationship geometry model and gene coding
Xiulian Qiu · Computer-aided engineering · 2008
To describe part information fully,six kinds of operators such as PAD and SHAFT and so on are defined by analyzing constitution of static of parts;two reasonable constraint features AND constraint feature and OR constraint feature are obtained by studying dynamic semantic relation between features,which are combined to implement dynamic semantic connection between static features and Part Semantic Relationship Geometry Model(PSRGM) is built based on feature-based modeling technology.According to dynamic generating process of PSRGM and coding structure,feature gene coding is completed,and DNA coding of part series is realized.Taking the crank for example,application of this method is illustrated.
