摘要

In this study, failure in the pump main shaft, supports, couplings and bearings due to excessive vibration are investigated by experimental and numerical modeling of the system behavior. The origin of fatigue failure is shown by the vibration measurement and its analysis as well as for the modification of system from any failure source finite element method is utilized. Finally, using of model based diagnosis and its analysis the modification of system will be done accurately without any more expenses.
