利用灰色理论的关联度分析实现了旋转机械故障的精密诊断 ,利用灰色模型( GM)实现了旋转机械的状态预测及故障预报 ,并用 C语言编制了一套完整的旋转机械灰色故障诊断、状态预测与故障预报软件。同时本文对某厂透平机进行了全面的计算机诊断与预报 ,通过现场对该透平机检查发现故障与本软件诊断结果一致 ,进而揭示了利用灰色理论开发旋转机械故障诊断和预报系统的可行性。本软件为旋转机械故障诊断专家系统的开发提供了新的借鉴 The gray theory (GM) was used to predict the state of the rotating machinery and to predict the failure. The complete gray system fault diagnosis, state prediction And fault forecasting software. At the same time, this paper conducts a comprehensive computer diagnosis and forecast for a turbine turbine. Through the on-site inspection of the turbine, the fault is consistent with the diagnosis result of the software, and then reveals the feasibility of developing the fault diagnosis and forecast system of the rotary machinery by using gray theory Sex. The software provides a new reference for the development of rotating machinery fault diagnosis expert system
