Open AccessExperimental studies on the energy dissipation of bolted structures with frictional interfaces: A review
Bolted joints play a more and more important role in the structure with lighter weight and heavier load. This paper aims to provide an overview of different experimental approaches for the dynamic behavior of ...

Dynamic performance of a novel tuned vibration absorber with nonlinear friction interfaces
A novel tuned vibration absorber with frictional interfaces (FTVA) is proposed in this study, combining the benefits of a tuned absorber and nonlinear dry friction dam** to dissipate energy. Firstly, the mec...

An Extensive Test Campaign of a Turbine Bladed Disk in the Presence of Mistuning and Underplatform Dampers, and Numerical Validation
The design of lighter and highly loaded aircraft turbo engines is driven by the need of improving their efficiency for a sustainable air propulsion. In this context, forced and self-excited vibrations in blade...

Open AccessStress recovery algorithm for reduced order models of mechanical systems in nonlinear dynamic operative conditions
Nonlinear forced response analyses of mechanical systems in the presence of contact interfaces are usually performed in built-in numerical codes on reduced order models (ROM). Most of the cases these derive fr...

Numerical assessment of friction dam** at turbine blade root joints by simultaneous calculation of the static and dynamic contact loads
In turbomachinery, the perfect detuning of turbine blades in order to avoid high cycle fatigue damage due to resonant vibration is often unfeasible due to the high modal density of bladed disks.
