Abstract: The existence of a “breathing” crack can not only cause variations in harmonic components but also produce extra transient components into vibration signals of a rotor system. In the present ...

Abstract: Application of viscoelastic materials in vibration and noise attenuation of complicated machines and structures is becoming more and more popular. As a result, analytical and numerical techniques ...

Abstract: Direct time integration methods are usually applied to determine the dynamic response of systems with local nonlinearities. Nevertheless, these methods are computationally expensive to predict the ...

Abstract: Although the study of vibration isolation has a very long history, when an isolated structure is so flexible that it cannot be properly approximated with a rigid body or a single-degree-of-freedom ...

Abstract: A new cepstral analysis procedure with the complex cepstrum for recovering excitations causing multiple transient signal components from vibration signals, especially from rotor vibration signals, ...

Abstract: The problem of flexible structure vibration isolation on a flexible foundation is analytically investigated by simplifying the vibration isolation as single axis isolation, which can be realized ...

Abstract: Bilinear time-frequency distributions, which provide simultaneous high resolution in both time and frequency domains, offer advantages for the analysis of vibration signals where the harmonic ...

Abstract: An analysis procedure, using the time-frequency distribution, has been developed for the analysis of internal combustion engine noise signals. It provides an approach making use of advantages of ...

Abstract: To improve the dynamic environment of a spacecraft, an octostrut vibration isolation platform is designed to replace the payload attach fitting, which can significantly attenuate the vibration ...
