中文摘要:

      地面试验评价是提高地面试验效能的有效措施，国内在电传飞控系统地面试验中未见应用。通过研究基于试验内容、试验方法、试验过程、试验数据处理等维度的电传飞控系统地面试验评价指标体系，建立了地面试验知识模型库，开展了密切值评价法、相关性矩阵法、专家打分法在电传飞控系统地面试验评价应用中的技术研究，给出了每种方法的计算公式和应用实例，总结了3种方法在实际应用中的选用原则。通过电传飞控系统地面试验评价技术的应用，可以提前发现试验方案的缺项，尽早开展优化工作，降低试验风险，提高试验效能。

英文摘要:

      The evaluation of ground test is an effective measure to improve the efficiency of ground test,which has not been applied in the ground test of the fly-by-wire(FBW) flight control system in China.By studying the evaluation index system of the ground test of the FBW flight control system based on the test content,test method,test process and test data processing,the knowledge database of the ground test is established,and the technical research on the application of the osculating value evaluation method,the dependency matrix method and the expert evaluation method in the ground test evaluation of the FBW flight control system are studied.The calculation formulas and application examples of each method are given,and the selection principles of the three methods in practical application are summarized.Through the application of ground test evaluation technology for FBW flight control systems,the shortcomings of the test programme can be identified in advance and optimisation work can be carried out as early as possible to reduce test risks and improve test effectiveness.
