摘要
随着现代飞机系统综合集成程度的大幅提高,系统间深度融合和交联,单个系统的功能需要多系统的协同才能实现,这对飞机总装阶段机上地面试验是否能有效验证产品功能提出了挑战。面对高度综合集成的飞机系统,对飞机内部各层级交联关系在生产制造阶段的解耦,是总装机上地面试验建立有效验证产品功能的关键。通过借鉴系统工程(Systems engineering,SE)原理和工具,建立飞机产品设计与飞机总装机上地面试验工艺设计间的内在继承关系,实现对产品内部交联关系的有效识别与解耦,并与总装机上地面试验硬件在环仿真(Hardware-in-the-loop)需求建立联系,基于此形成了飞机系统试验解耦“V”模型的一般性方法框架。该方法在飞机电源系统机上地面试验应用中有效解析了系统试验仿真需求,结合飞机总装阶段试验环境特性,继而形成相应总装电源系统测试环境。
With the rapid improving of modern aircraft system integration,deeply cross-linking between systems,the function of a single system needs the cooperation of multiple systems,which challenges whether the ground test on aircraft can effectively verify the product’s function in aircraft assembly stage.In the face of highly integrated aircraft systems,how to decouple the cross-linking relationship at different levels of aircraft design in manufacturing stage is the key to establish the effective verification of product function in the ground test on aircraft.By referring to the principles and tools of system engineering(SE),it is established that the internal inheritance relationship between aircraft product design and ground test process design in aircraft assembly stage,which can effectively identify and decouple the internal cross-linking relationship of products.And the cross-linking relationship shows the requirements of hardware-in-the-loop simulation for ground test on aircraft in aircraft assembly stage.Based on these,the general method framework of decoupling“V”model of ground test on aircraft is formed.The initial application of the method showed that the electrical system test simulation requirements are effectively analyzed,and combined with the environment characteristics in aircraft assembly stage,it formed the corresponding test facilities for electrical system.
