Effect of particle shape and fragmentation on the response of particle dampers [PDF]

open access: yes, 2013
A particle damper (PD) is a device that can attenuate mechanical vibrations thanks to the dissipative collisions between grains contained in a cavity attached to the vibrating structure.

Experimental Study on a Hybrid Coupling Beam With a Friction Damper Using Semi-steel Material

open access: yesFrontiers in Materials, 2019
RC coupling beams have been reported to have had serious damages during the 2008 Wenchuan earthquake. Beams are very difficult to repair once cracks occur.

Enhancing Friction Pendulum Isolation Systems Using Passive and Semi-Active Dampers

open access: yesApplied Sciences, 2020
Friction pendulum systems (FPSs) are a common solution for isolating civil engineering structures under ground movements. The result is a base-isolated structure in which the base exhibits low shear stiffness in such a way that the input energy of the ...

Simulation of a mechanical thrombectomy device based in the use of self-expandable stents for the blood clots extraction [PDF]

open access: yes, 2011
Recently, we have presented some studies concerning the analysis, design and optimization of one experimental device developed in the UK - GPTAD - which has been designed to remove blood clots without the need to make contact with the clot itself ...

Design of a frictionless magnetorheological damper with a high dynamic force range

open access: yesAdvances in Mechanical Engineering, 2019
This article discusses an increase in dynamic force range in a spring–damper unit achieved by elimination of sealings’ friction. This friction is a part of damping force that cannot be controlled; therefore, it is undesirable in magnetorheological ...

Development of a Multiaction Hybrid Damper for Passive Energy Dissipation

open access: yesShock and Vibration, 2018
A multiaction hybrid damper (MHD) is designed to have independent hysteretic characteristics under small and large loading conditions, and its control performance for building structures excited by wind or earthquake load is verified. The MHD is composed

Effectiveness of friction dampers on seismic response of structure considering soil-structure interaction

open access: yesGrađevinar, 2020
The effect of soil structure interaction (SSI) on a single degree of freedom system with and without friction damper is analysed in the paper. The structure with different mass, stiffness and soil conditions was prepared and analysed for ten different ...
