摘　　要：针对工程机械驱动桥装配序列规划中缺乏基于知识的推理决策,难以实现复杂产品智能化装配的问题,提出一种基于语义工艺知识的装配序列规划方法。构建了驱动桥装配语义工艺知识信息模型,表达子装配体层级结构信息、属性信息和装配语义信息。通过建立装配序列规划本体,并将SWRL规则引入装配本体,研究了工艺知识的语义表示和推理决策。采用Neo4j构建驱动桥工艺知识图谱,实现了典型结构子装配体装配序列快速识别。通过量化零件几何、物理属性和装配工艺信息对装配效率的影响,生成装配权重序列,并利用SWRL规则迭代修正形成非典型结构子装配体装配序列。以某型号压路机驱动桥装配序列生成与仿真,验证了该方法的可行性,为知识驱动的复杂产品装配序列规划提供参考。In response to the lack of knowledge-based reasoning and decision-making in the assembly sequence planning of construction machinery drive axles,which makes it difficult to realize intelligent assembly of complex products,a method for assembly sequence planning based on semantic process knowledge was proposed.The semantic process knowledge information model of the drive axle assembly was constructed to express the hierarchical structure information,attribute information,and assembly semantic information of sub-assemblies.By establishing an assembly sequence planning ontology and introducing semantics web rule language(SWRL)rules into the assembly ontology,the semantic representation and reasoning and decision-making of process knowledge were studied.The process knowledge graph of the drive axle was constructed using Neo4j,and the assembly sequence of typical structural sub-assemblies was quickly identified.By quantifying the influence of geometric properties,physical properties,and assembly process information of parts on assembly efficiency,the assembly weight sequence was generated,and the assembly sequence of atypical structure sub-assemblies was iteratively modified by SWRL rules.Finally,the feasibility of the proposed method was verified by generating and simulating the assembly sequence of the drive axle of a certain model of road roller,providing a reference for knowledge-driven complex product assembly sequence planning.
