摘要:
飞机测试可模拟飞行环境，验证飞机功能符合性和性能精准性。近年来，飞机装配过程已逐步转变至三维装配工艺设计，而飞机测试仍局限于通过文档形式进行测试任务描述和过程执行。基于模型定义（MBD）对飞机测试顶层设计进行了研究，提出测试工艺设计概念和测试工艺数字化定义方法。将飞机全过程测试分为4个阶段，形成从测试设计到测试结果的工艺模型定义，并实现部分工程化验证。结果表明：基于MBD的测试工艺数字化定义结果可作为唯一数据源，实现飞机测试的统一表达与信息传输。

Abstract:Aircraft test can simulate the flight environment to verify whether the aircraft functions meet the requirements and the performance is accurate. In recent years, the aircraft assembly process has gradually turned into three-dimensional design, while aircraft test is still limited to the description of test tasks and process execution in the form of documents. Based on the Model Based Definition (MBD), the top-level design of aircraft test is studied, and the concept of test process design and the digital definition method of test process model are proposed. The whole process of aircraft test is divided into four stages, completing process model definition from test design to test results and achieving partial engineering verification. The results show that the MBD-based digital definition result can be used as the only data source to realize the unified expression and information transmission of aircraft test.
