Influence of Internal Rubber Damper on Cable External Viscous Damper Effectiveness [PDF]

Eng, 2022
In practice, the internal rubber dampers are widely installed inside the cable guide pipe between the external viscous damper and the cable anchorage. In order to study the effect of the internal damper on the performance of the external viscous damper, the theoretical analysis model of a taut cable with an internal rubber damper and an external ...

Damping Characteristics of a Novel Bellows Viscous Damper. [PDF]

Sensors (Basel)
Micro-vibrations during the operation of space remote sensing equipment can significantly affect optical imaging quality. To address this issue, a bellows-type viscous damper serves as an effective passive damping and vibration isolation solution. This paper introduces a bellows-type viscous damper with adjustable damping capabilities, designed for mid-

The Effect of Viscous Dampers on the Seismic Performance of Curved Viaducts with the Combined Use of Steel Stoppers

Applied Sciences, 2022
Viaducts with roller bearings are subject to large displacement, which could lead to the collapse of the deck during earthquakes. This study attempts to prevent large displacements by installing steel stoppers at both sides of roller bearings.
