Abstract: Aiming at the problem of pure mathematics based assembly sequence generation methods had difficulty in explicitly representing the semantics of knowledge and experience required in the generation of valid assembly sequences,the ontology was introduced into automatic generation research of assembly sequences.Starting from the subassembly relation of assembly,an assembly information model was established through combing the information of positioning,interference and connection relations.Assembly information ontology was constructed and some ontology rules were defined to explicitly represent the semantics of knowledge and experience based on the established model.On the basis of the constructed ontology and the defined rules,an automatic generation method of assembly sequences was designed by determining the validity of assembly sequences.An example was presented to illustrate the work process and to verify the effectiveness of the method at the aspect of reducing invalid assembly sequences.
