Abstract
Unbalance is among the most common mechanical faults in rotating machinery, and is of particular interest to the aviation industry. A state of the art machine fault simulator has been used in order to recreate a range of unbalance faults which have been studied in detail from the perspective of fault localisation. High fidelity finite element models have been created in NASTRAN NX and experimentally validated against results for the machine fault simulator. The applicability of such simulations is discussed from an IVHM perspective, along with the potential for such research to influence the development of future engine health management with respect to improved safety and maintenance.
