Abstract: The authors describe an integrated approach to the modelling and active control of lateral vibrations in turbomachinery. Starting with consideration of the control of multiple rotor bending modes, ...

Abstract: Some recent experimental studies have been concerned with the stabilization of rotating machinery through control action applied at critical points on the rotor. These studies have tended to ...

Abstract: In this paper, the authors describe a systematic procedure for classifying the modes of operation of ER fluids. The classification is achieved by treating an ER device as a generalized modulator ...

Abstract: A new approach is proposed to the identification of the eight linearized coefficients which characterize the dynamics of a journal bearing oil-film. The use of pseudo-random binary forcing ...

Abstract: In this paper the authors describe an experimental study to identify the damping laws associated with a squeeze-film vibration damper. This is achieved by using a nonlinear filtering algorithm ...

Abstract: The electro-rheological (ER) effect is the name given to the phenomenon whereby the resistance to flow of certain special fluids can be controlled through the application of an electric field. ...

Abstract: This paper describes the application of sequential frequency domain techniques to the estimation of mass, stiffness, and damping parameters using measured frequency response functions from a portal ...

Abstract: This paper describes progress on a new technique to detect pipeline features and leaks using signal processing of a pressure wave measurement. Previous work (by the present authors) has shown that the analysis of pressure ...
