To achieve sustainability goals and reduced emissions, new aero-engine designs have to be lighter, at the cost of increased vibration levels. Uncontrolled, vibrations threaten the integrity of components that are already highly stressed by static loads, and this can result in early failures. Therefore, the correct analysis of the dynamic response of the engine components is of uttermost importance, but such analysis is limited by the lack of fully predictive modelling approaches. This lack is partly due to the presence of friction joints in the engine, which are difficult to model because of their complex underlying physics and a lack of experimental data from the contact interfaces.
