MECHANICAL VIBRATION MONITORING AS A MODERN MAINTENANCE TECHNOLOGY FOR MACHINES (KEY IJP************854)

• Sibete Godfrey Ayeabu

Abstract

Mechanical vibration monitoring technology is a vibration based monitoring of faith from gas turbine rotor shafts. The paper highlights vibration monitoring technology, vibration monitoring techniques, vibration analysis, Dynamics of bean vibration theory and monitoring instruments fitted on test engine. A conclusion drawn that vibration amplitude on bearing along a rotor shaft depends on the distance of the bearing from the load end of the shaft which is taken as the reference point, and that the size and location of a crack from the reference axis are proportioned to the magnitude of the vibration amplitude. The reseachers therefore recommended that some environmental factors should be considered while carrying out vibration based simulation of gas turbine rotor shafts and artificial neural networks developed to validate modelling in rotor shaft defeats should be given more attention.
