Effect of Adding a Styrene-Butadiene Rubber Damper to A Sled Sample and Extraction of Its Equivalent Stiffness and Damping [PDF]
International Journal of Advanced Design and Manufacturing Technology, 2023 Protection of sled systems from destructive vibrations is inevitably under attraction due to the importance of sled testing in the aerospace industry. A pair of SBR dampers were used between the slipper and the sled body to reduce vertical vibrations, so

Seismic Performance Evaluation of Building-Damper System under Near-Fault Earthquake
Shock and Vibration, 2020 The building-damper system designed by a seismic code is usually considered to be able to withstand the attack of strong earthquakes. However, near-fault earthquakes, especially those with the forward-directivity effect, might cause early and unexpected ...

A Concentric Design of a Bypass Magnetorheological Fluid Damper with a Serpentine Flux Valve
Actuators, 2020 This work presents a new concentric design structure of a bypass magnetorheological (MR) damper with a serpentine flux valve type. In this design, the serpentine valve is installed not in the middle of the piston but on the bypass channel of the damper ...

The model of working process of the boom lifting and lowering mechanism with an additional damper in the form of hydrodiode [PDF]
Омский научный вестник: Серия "Авиационно-ракетное и энергетическое машиностроение", 2023 In hydraulic and pneumatic systems, due to the many factors of their operation, pressure and flow fluctuations inevitably occur. Such fluctuations are formed during the operation of gas-liquid aggregates, during the passage of resistance flow, and ...

Physica A: Statistical Mechanics and its Applications, 2019 As an application of the classically decayable correlation in a quantum chaos system maintained over an extremely long time-scale (Matsui et al, Europhys.Lett. 113(2016),40008), we propose a minimal model of quantum damper composed of a quantum harmonic oscillator (HO) weakly interacting with a bounded quantum chaos system.

APPLICATION OF MR DAMPERS TO VARIABLE DAMPERS
Doboku Gakkai Ronbunshu, 2004 ダンパーの減衰力を任意に変化させることができれば, 橋梁の地震応答を抑える上で有利であり, 構造物の応答に応じて特性を変化させることのできるバリアブルダンパーの利用が効果的であると考えられている. 本研究では, 電流で減衰力を制御可能なMRダンパーを用いたバリアブルダンパーの有効性を実験, 解析の両面から検討する. 小型MRダンパーの特性を明らかにすることを目的として繰り返し載荷実験を行った後, 模型橋の振動台加振実験を行い, 地震時のMRダンパー及び橋梁の挙動を調べた. また, バリアブルダンパーをモデル化し, 橋の地震応答を地震応答解析によってよく再現できることを示した.
