接口控制是航天型号及其各级产品(系统、分系统、设备)总体设计的关键环节之一。本文提出了接口识别、分类和定义的方法和步骤,提供了接口控制文件的编制和更改流程,以及一些有用的接口控制工具,可指导航天型号设计师和管理人员对接口实施适当的控制,有助于保证接口的相容性,提高航天型号研制的接口控制效率,改进接口定义和控制的过程,并适时更新相关知识。 Interface control is one of the key aspects of the overall design of aerospace models and their products (systems, subsystems and equipment) at all levels. This paper presents methods and procedures for interface identification, classification and definition, provides the process of preparation and modification of interface control files, and some useful interface control tools to guide aerospace model designers and managers to implement proper control over interfaces. There are Help ensure the compatibility of interfaces, improve the efficiency of interface control developed by aerospace models, improve the process of interface definition and control, and update related knowledge in time.
