Abstract
In industrial applications the vibration analysis mostly focuses on the main components, while accessories, such as pumps, electronics or pipe work are often neglected. This can lead to failures in these support systems, which can lead to performance reduction, shut down, or in the worst case catastrophe failure of the application due to secondary effects. One such accessory system is the fuel manifold of an aero engine, which delivers the kerosene to the fuel injectors. Previous experimental work has highlighted a strong nonlinear dynamic response of this setup, making an accurate prediction during the design process very challenging. In this study, a low order nonlinear modelling approach for fuel supply pipes, based on linear finite element and implicit nonlinear element analysis, is presented and its advantages and limitations are discussed.
