Study on separation of the vibration response of diesel vibration inner forces based on the blind signal separation

An approach based on blind extract and deflation is applied in blind separation of the vibration response of dynamic forces of diesel at different locations in order to improve the accurate of the statues monitoring of diesel. The scale factors indeterminacy of blind signal separation is solved by this approach in a in a relative sense. This method is discussed in this paper, and the results of simulation proved it effective. In the end, the Piston Slap of diesel is extracted from the vibration signals of diesel. The results show that the response of the Piston Slap was separated successfully by the discussed method.
