摘　　要：为满足协同装配设计所需的信息,分析了协同装配中预装配、装配顺序规划和装配路径规划等活动对装配信息模型的需求,给出了协同装配模型的信息构成,包括零件信息、装配信息和设计决策信息3部分。提出了装配结和装配基元的概念,前者简化了装配约束关系的描述,后者反映了装配顺序及装配操作;由此构成了便于计算机存储的协同装配模型的信息表达方案以及指导预装配活动的框架视图表达方案。结果表明,该模型能有效地支持协同装配设计的实现。Based on requirement analysis of the preassembly, assembly sequence, and assembly route of cooperative product assembly activity, an information model including part information, assembly information and decision-making information in an assembly design was presented to satisfy all information requirements of the cooperative assembly design. The part assembly restriction relations, assembly sequence and operations were described by introducing an assembly knot and an assembly unit. An integrated information model was organized in the framework mode. The results show that the model is easy for storage and has availability to support cooperative assembly design.
