Abstract :
This paper describes how commercial finite element packages may be used to simulate rotor faults and hence enhance the capability of practical condition monitoring schemes. Some known causes of inaccuracy between models and experimental data are accounted for and the results compared with experimental data. An accurate model of the machine under faulted conditions is developed which is used to determine the monitoring strategy for less common faults
