Journal of Marine Science and Engineering, 2022 Propeller-induced longitudinal vibration resonance in marine propulsion shafting systems causes great harm to the hull structure and is the primary source of shipboard noise. Integrating a friction damper with designed parameters into thrust bearings can

A Hybrid Damper with Tunable Particle Impact Damping and Coulomb Friction
Machines, 2023 A particle impact damper (PID) dissipates the vibration energy of a structure through impacts within the damper. The PID is not commonly used in practice mainly because of its low damping-to-mass ratio and the difficulty in achieving its optimal design ...

FLUTTER ANALYSIS OF BLISKS WITH FRICTION RING DAMPERS [PDF]
Proceedings of Global Power & Propulsion Society, 2022 Aeroelastic flutter is a phenomenon when blades experience an aeroelastic selfexcitation from the surrounding air resulting in the full destruction of aeroengines. It poses a big challenge for aeroengine bladeddisks design, especially for integrally bladeddisks (blisks).

Numerical Study of Horizontal Friction Dampers Made of Steel and Brake Pads in Chevron frame under Cyclic Loads [PDF]
پژوهشهای زیرساختهای عمرانی, 2022 Observations of damage to buildings in recent earthquakes indicate that some of the damage was in the area of welded joints. Due to the weakness in the joints, the idea of using a horizontal friction damper using brake pads in bracing openings ...

Behavior of multidirectional friction dampers
Journal of Vibration and Control, 2020 Earthquakes are catastrophic events causing loss of lives, injuries, and extensive losses in properties. Majority of the life and property losses of earthquakes are dependent on the incapabilities of the building stock to resist earthquakes. Although unsuitable design, analyses, and production techniques play a major role as the main reasons for the ...
