摘　　要：面向装配信息数据表达与飞机零部件装配夹具协同设计问题,阐述了飞机装配对象及其夹具多域集成建模过程,该建模过程给出了多域集成模型的知识框架.其次,定义各领域信息构成,全面系统地描述了装配工艺规划的所有数据.提出了装配对象与装配夹具之间互映射机理,详细阐述了互映射过程中所需的4个关键知识点.最后以翼尖小翼为实例,证明建模方法的可行性与有效性,使夹具设计更加系统化,提高了飞机结构、装配工艺规划和工装设计的协同设计效率和响应速度.Considering the problem of aircraft part assembly fixture collaborative design and assembly data expression, the modeling process of aircraft assembly object and its fixture multi- domain integration was discussed. The modeling process provides the knowledge framework of multi-domain integration model. The information composition of all domain, and describe all the data in the assembly process field were defined. At the same time, the mapping mechanism between assembly object and assembly fixture, and elaborate four key knowledge points included in mapping process was proposed. Finally, the effectiveness and feasibility of the method are demonstrated by winglet example, making it more systematic and improving the response speed ＆ the collaborative design efficiency of aircraft structure, assembly process planning, and tooling design.
