Vibration Analysis

Example Campbell Diagram

Following a compressor stator blade failure in a UK power station, EKES was commissioned to carried out a full vibration analysis to ascertain the possible cause of failure.

EKES created a 3D FEA model of the stator vane and determined the component's natural frequencies and EKES created a 3D FEA model of the stator vane in order to determine the component's natural frequencies and associated mode shapes. The Campbell diagram which was produced enabled the predicted natural frequencies to be compared against possible forcing excitations.
