For highly-loaded rotor systems of aero-engines, residual preloads in the same row of bolts
are generally asymmetric after multiple operational cycles. The asymmetry in residual bolt …

This paper investigates the effects of fretting wear on frictional contacts. A high frequency
friction rig is used to measure the evolution of hysteresis loops, friction coefficient and …

The dynamic response of individual components in an assembled structure shows high
accuracy compared to experimental measurements of the system response. However, when …

Bolted joint structure is widely utilized in the aeroengine compress rotor systems with
convenience in assembly and maintenance. Due to the inherent structure discontinuity and …

This paper presented a non-linear modeling approach for bolted joint connection interfaces
and identified the micro-slip model's parameters through quasi-static experiments based on …

Underplatform dampers are widely used in turbomachinery to mitigate structural vibrations
by means of friction dissipation at the interfaces. The modelling of such friction dissipation is …

Accurately predicting the nonlinear dynamic response of aero-engine components is critical,
