In any rotating machinery, unbalance and misalignment of the rotor are the two major malfunctions. Perfect alignment of shafts never exists. Improper aligning of shafts through couplings often leads to severe vibration problems in many rotating machines. In the present work effect of flexible coupling misalignment on lateral vibrational characteristics of a rotor-bearing system has been studied in an Object Oriented Programming framework using finite element method. An off-line rule based expert system has been developed for condition monitoring of a gas turbine, which predicts the machine condition severity and the cause of the problem. The system is implemented in C++.
