摘要
从理论和实践上分析了转子存在裂纹情况下的频率变化的特征.并利用频谱分析法成功地诊断了转轴存在裂纹故障的设备,验证了该方法的有效性,为出现类似频谱现象的设备的分析提供参考.
This work analyzed the frequency characteristics of rotor under the circumstance of cracking. With the use of spectrum analysis method, we successfully diagnosed the crack fault of rotating equipment, verified the effectiveness of the method we proposed, provided a reference for analysis of the equipment of a similar spectrum phenomena.
