摘　　要：针对飞机水平尾翼故障诊断研究的具体需求,采用基于MFC的Vega软件开发了可视化故障诊断虚拟实验平台。根据不同飞行任务特征,对水平尾翼进行了载荷分析,利用概率断裂力学原理建立了水平尾翼疲劳裂纹的数学模型,实现了故障数据的动态获取和故障形成过程的可视化显示。实验结果表明,该实验平台能为研究人员提供可靠的诊断依据,还能提供直观的交互界面,基本满足水平尾翼故障诊断验证要求。According to the needs of horizontal tail fault diagnosis, a visualization experiment platform of fault diagnosis was developed by using Vega based on MFC frame. The load of the horizontal tail was analyzed from the characteristics of different flying tasks. The mathematic model of the fatigue crack was built by using Probabilistic Fracture Mechanics. The fault data couldbe obtained dynamically and fault establishment could be displayed visually. The simulation experiment conclusion shows that the basic requirement of horizontal tail fault diagnosis can be satisfied. This platform can not only provide the credible groundwork of diagnosis for researchers, but also furnish an intuitionistic interactive environment.
