滚动轴承磨损的模糊诊断与分析

Application of Vibration Monitoring in Diagnosis of Fault of Ventilation Equipment in Underground Coal Mine

本文通过对机器振动状态及故障的模糊分类 ,采用模糊数学中模糊识别和贴近度的概念所测得的机器当前的运行状态与标准的运行状态进行比较 ,来识别机器当前的运行状态及发展趋势。

The paper presents a description of the method for fault diagniosis of ventilation equipment with vibation technique,the method for defining the fault due to imbalance of rotor based on the characteristic of vibration as well as the method for determining the operational status of equipment according to the intensity of vibration of bearings.
