摘　　要：为了能充分利用汽轮机轴心轨迹的形状和动态特性信息 ,使其能够更好地为故障诊断服务 .本文介绍了轴心轨迹自动识别系统的结构、功能及识别方法 ,该系统充分运用了神经网络的结构和功能 ,运用BP网络构建识别系统 ,该系统在一定的识别率下实现了对汽轮机转子轴心轨迹的自动识别 .The purpose of this paper is to discuss the full use of the shape and dynamic feature of orbit of shaft centerline of marine turbine,and to make good use of it for fault diagnosis. A kind of automatic recognition system was designed. The structure,function and means of recognition of the system were introduced and the BP neural network was in use for the system . The system can automatically recognize the orbit of shaft centerline of marine turbine rotor for a certainty of identification probability.
