【摘要】 根据模型试验中活动导叶上出现的空化现象 ,利用CFD软件分析了导叶与导叶轴颈过渡圆弧对空化性能的影响。在导叶轴颈强度允许的情况下 ,应该尽量减小其过渡圆弧的尺寸 ,从而减小导叶的空蚀更多还原

【Abstract】 This paper presents a review of the most recent developments in the field of the fault diagnosis and detection of induction motors. It covers the application of wavelet analysis, artificial neural networks, fuzzy logic systems, expert systems that can be integrated into each other and also with mote traditional techniques.更多还原
