SYSTEMS AND METHODS FOR ENGINE VIBRATION MONITORING

Provided are methods and systems for monitoring vibration in an engine (110). A vibration signal from at least one sensor (416) coupled to the engine (110) and a speed signal representative of an operating speed of the engine (110) are received at a computing device. A target frequency of the engine (110) is determined, at the computing device, based on the speed signal. A center frequency of a filtering system (430) is altered, via the computing device, so that a pass-band of the filtering system (430) contains the target frequency. The vibration signal is filtered with the filtering system (430) to obtain a filtered vibration signal. A vibration amplitude for the engine (110) is determined, at the computing device, based on the filtered vibration signal.
