Abstract

A method of monitoring periodic vibrations of machine equipment with a number of machine components which generate vibrations, in particular for monitoring the periodically repeated ignition sequence in a multiple cylinder combustion engine, in particular a number of diesel engines connected in parallel in a ship. Vibration signals (A) from sensors, which are disposed on a joint gear box on the extension of the respective engine axle, are sampled upontriggering (B) from a trigger sensor, which is disposed on the cylinder which is first in the ignition sequence of the respective engine, and are digitized to form time series, whereupon mean values are calculated on the basis of a plurality of such time series so as to form a characteristic ignition sequence. According to the invention the vibration signals (A) are additionally converted (FFT) to the frequency domain, and the peaks in the frequency spectrum are reconverted to time intervals for fine-correction of the respective characteristic ignition sequence.
