Independent component analysis of a single measured mixing signal, that is single channel Independent component analysis (SCICA), has been widely used in feature extraction of a signal. In this paper we provide a example of using single channel ICA for extracting the feature of a abnormal running condition of a turbine from measured vibration signals, in order to show the effect of SCICA. The bearing...
Washing machines are typical systems with electromechanical coupling vibration. A novel approach is presented for modeling of an inclined drum washing machine system in this paper. Its Lagrangian function and Rayleigh dissipation function are obtained firstly. Then, its detail electromechanical coupling model is established based on Euler-Lagrange theory and variational principles. Notation that the...
On the basis of the current sheet model, a new analytical solution for permanent magnet (PM) bearings is developed. Compared with analytical methods based on the coupling energy model and the magnetic dipole model, the proposed one is more physically intuitive and convenient for engineering designers. According to the analytical model, the thrust characteristics of a novel PM thrust bearing is studied...
