摘要

为了有效地识别振动信号中存在的虚假信号

采用全息谱方法对具有时间延迟和相位延迟的理想测量面和典型测量面形状误差转子的振动信号进行了理论分析和试验研究.同时

分析并讨论了两种情况下测量面形状误差引起的虚假振动信号对实际振动信号的影响

总结了两种情形下的振动和全息谱特征

得到了具有测量面形状误差的转子振动信号特征.通过试验和现场数据验证结果

与理论分析结果一致

从而为现场转子测量面形状误差的诊断提供了新的识别理论和方法.

Abstract

To effectively identify the illusory components in vibration signal

both rotor vibration signal of rotor with ideal shape at measurement section and illusory signal generated due to the typical shape error at measurement section are analyzed to summarize the signal characteristics adopting holospectrum method. Simultaneously

the influences on real vibration signal from shape error at measurement section and the characteristics of real vibration signal of rotor are discussed. The results are verified by the analysis of experimental and practical signals to provide a new method for actual monitoring and diagnosis of rotary machinery.
