Modal Testing and Finite Element Analysis of Crack Effects on Turbine Blades
The study of vibration response of a turbine blade helps to detect the crack presence in the blade which alters its dynamic characteristics. The change is characterized by changes in the modal parameters associated with natural frequencies. In this paper, study of vibration response is made for turbine blade in the presence of a crack like defect. Turbine blade is initially assumed as a cantile...
متن کاملResearch 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 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 کاملHarmonic component detection: Optimized Spectral Kurtosis for operational modal analysis
This work is a contribution in the field of Operational Modal Analysis to identify the modal parameters of mechanical structures using only measured responses. The study deals with structural responses coupled with harmonic components amplitude and frequency modulated in a short range, a common combination for mechanical systems with engines and other rotating machines in operation. These harmo...
متن کاملFrequency Domain Techniques for Operational Modal Analysis
Operational Modal Analysis, also known as Output Only Modal Analysis, has in the recent years, been used for determination of modal parameters of civil engineering structures and is now becoming widely used also for mechanical structures. The advantage of the method is that no artificial excitation needs to be applied to the structure, or force signals to be measured. In this paper, the non-par...
