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％.
