Research in the Operational Modal Analysis of Rotating Machinery Reducer
In operational modal analysis process of the rotating machinery, it is always difficult to adopt usual modal analysis methods in parameter correction because of the modal parameter identification problems caused by harmonic modes. A technique to distinguish harmonic and structural modes is proposed here, that is, through frequency domain decomposition (FDD) of the vibration signals power spectr...
متن کاملComparison of Methods for Separating Excitation Sources in Rotating Machinery
Abstract Vibro-acoustic signatures are widely used for diagnostics of rotating machinery. Vibration based automatic diagnostics systems need to achieve a good separation between signals generated by different sources. The separation task may be challenging, since the effects of the different vibration sources often overlap. In particular, there is a need to separate between natural frequencies ...
متن کاملOperational Modal Analysis on Structures with Rotating Parts
Operational Modal Analysis was originally invented for vibration analysis on civil engineering structures exposed to ambient excitation being purely stochastic and broadband in nature. When performing Operational Modal Analysis on civil or mechanical engineering structures with dominating rotating parts, the original algorithms are often inadequate in providing accurate results due to determini...
متن کاملDiagnosis for Rotating Shaft Using Adaptive Modal Parameter Identification Method
It's important to understand the dynamic behavior of a structure under operating condition from the view point of vibration shapes of a structure on well excited frequency components and accurate identification of amplitude on each point of a structure. Operating Deflection Shapes (ODSs) can be defined for nonlinear and non stationary structural motion. ODSs provide very useful information for ...
متن کاملRotating Machinery for Condition Monitoring
Novelty detection has been developed into a state-of-the-art technique to detect abnormal behavior and trigger alarm for in-field machine maintenance. With built-up models of normality, it has been widely applied to several situations with normal supervising dataset such as shaft rotating speed and component temperature available meanwhile in the absence of fault information. However, the resea...
