研究了基于MBD的航天产品装配工艺规划技术,首先针对航天产品的装配工艺特点进行装配信息建模,构建基于设计MBD模型的MBD装配模型,MBD装配模型包含了装配规划模型和装配仿真模型,分别用于装配工艺规划和装配工艺仿真;其次,引入结构化设计思想,通过产品、工艺、工厂、资源四者的关联,构建基于MBD装配模型的P-P-P-R装配工艺模型;同时,通过信息集成,构建以P-P-P-R模型为核心的装配工艺信息模型;最后提出了基于装配工艺信息模型的装配工艺规划流程和内容.以某型号火箭进行了实例验证.

英文摘要：

It proposed a MBD-based assembly process planning technique for aerospace products. Firstly, according to the characteristics of the aerospace products it builds the MBD assembly model based on the MBD design model by assembling information modeling, and the MBD assembly model is constructed by the process planning model and the process simulation model; Secondly,introduces the structured design ideas and builds the MBD assembly model based on PPPR assembly process model by connecting the product,process ,plant and resource; Then, build the assembly process information model by the information integration; At last, propose the assembly process planning procedures and content by instance validation of a model rocket.
