摘　　要：故障诊断是一门交叉学科,广泛应用于各个领域,在飞机维修虚拟训练系统(VMTS,virtual maintenance training system)平台基础上,提出基于虚拟仪器进行测试、故障定位的仿真训练策略,构建了基于需求的虚拟测试仪器模型框架,并在VMTS系统中得到应用;通过虚拟测试仪器与推理模块协同配合的方法解决了维修虚拟训练过程中普遍存在的故障诊断类型套路化问题,并且能够完成复杂状态下的故障诊断任务,满足各种故障诊断训练要求,最后以尾桨故障诊断为例,证明该方法的可行性。In this paper, on the basis of the Virtual Maintenance Training System platform, it presents a simulation training strategy which is based on virtual instrument testing and fault location, builds a virtual test instrument model framework and applies in VMTS. Virtu- al testing instrument coordinates with inference modular solves the routine problems of fault diagnosis in the process of virtual maintenance training system, and it can complete fault diagnosis task in the complex state and meet the requirements of various diagnostic training. Final- Iv, it demonstrates the feasibilitv of the method which takes a tail rotor fault as an example.
