摘要:
为了解决传统的频谱技术在转子-轴承系统故障诊断中存在的问题，采用全频谱技术诊断方法，对油膜诱发转子失稳故障进行诊断。该方法可以完整描述转子的进动状态，对整个进动平面进行监测，且能够同时容纳空间上两个垂直的传感器的信号。结果表明，全频谱技术可以对油膜诱发转子失稳的故障进行有效诊断，提高了故障诊断的便捷性与准确度。
Abstract:
In view of the fact that the traditional spectrum plot can only express vibration information in a fixed direction in the fault diagnosis of rotor-bearing system，which has poor reliability and contingency，and causes misjudgment of the results.In this paper,the fault diagnosis of oil film induced rotor instability is carried out by using the full spectrum plot.The full spectrum plot can completely describe the rotor precession state and monitor the whole precession plane,and it can accommodate the signals of two vertical sensors in space.The results show that the full spectrum plot can diagnose the fault characteristics of oil film induced rotor instability，and it can improve the convenience and accuracy of fault diagnosis.
