摘要: 在自动聚类分析的基础上, 根据某汽轮机减速箱运行状态特征数据, 采用Kohonen网络方法, 确定该机械的运行状态, 结果与选用其它方法所确定的结果一致。该方法能实现对汽轮机减速箱运行状态的监控Abstract: The application of Kohonen network to the diagnosing of mechanical failure was studied. The results show that the Kohonen network can discribe the machine's running through testing the characteristic data of decelerating box. Compared with other methods, it is pointed out that this method is reasonable, and this method can monitor and control the decelerating box running.
