Knowledge-driven assembly process reconfiguration method for aerospace complex products
Aiming at the problems of aerospace complex product assembly semantics without standard constraints,difficult reuse of assembly process and long assembly design cycle,a knowledge-driven assembly process reconstruc-tion method for aerospace complex products was proposed.By analyzing the correlation between satellite assembly semantics and process elements,the logical relationship and multi-level ontology model of satellite product assembly process knowledge system were constructed,and the hierarchical association representation of satellite product as-sembly knowledge was realized.The assembly process knowledge mining model of satellite products was de-signed.On this basis,the assembly process similarity calculation and improved AP clustering algorithm were used to mine the typical assembly process knowledge,and the effective reuse of historical assembly process knowledge was realized.Taking a certain satellite product as an example,a rapid configuration generation system for assembly process was developed.The successful implementation of this technology in aerospace enterprises verified the effec-tiveness of the proposed method,which shortened the generation cycle of assembly process description content and supporting information by 52%.
