摘　　要：采用了"顶层基本骨架"的概念和自顶向下的设计方法,通过该骨架收集单机设备的机械接口信息,并将信息传递至各直属件骨架模型中作为直属件设计的输入。直属件完成详细设计后,单机机械接口的最新变更信息通过骨架传递至直属件模型,确保直属件模型能够及时更新,同时实现了直属件的关联设计和自动装配,其设计失误率降低至1.6%,设计周期缩短约35%。此方法可为航天器直属件设计提供参考。The paper brings forward a concept of top basic skeleton and top-down design method for special parts for integration of a spacecraft, which means the unit mechanical interfaces infor- mation is collected through a skeleton model and transmitted to the skeleton model as design inputs. With the special parts design completed, the latest change information of the unit me- chanical interfaces shall be transferred to special part model via the skeleton to ensure the model can be updated in time, and at the same time the associated design and automatic assembly of the special parts are realized. This method, with which the design error rate can be reduced to 1.6 and the design time shortened about 35 %, can provide a reference for the design of special parts for integration of spacecraft
