Implementation of Structural Control with Viscous Damper

Applied Mechanics and Materials, 2011
For the sake of safety of structures subjected to abnormal loadings, damper could be one of the effective devices to reduce the responses by the energy dispassion functions. Key points in the process of development and application of damper and aseismatic engineering are narrated.

The Extended Theory of the Viscous Vibration Damper

Journal of Applied Mechanics, 1955
Abstract The paper extends the theory of the Viscous Vibration Damper either tuned or untuned to multimass systems and shows how an optimum damper can be designed for any installation. Special formulas are derived for the two mass plus damper systems.

Torsional Viscous-Friction Dampers

Journal of Fluids Engineering, 1949
Abstract This paper describes the large torsional viscous-friction or “Lanchester” dampers manufactured by the author’s company for use on Diesel engines. Some properties of the new silicone fluids, that are necessary for damper design, are given.

Self-leveling viscous elastic damper

The Journal of the Acoustical Society of America, 1983
A self-leveling viscous elastic damper comprising an inner member at least partially received in an outer member and joined to the outer member with an elastomeric shear spring. A main fluid chamber is included in the outer member in communication with a second fluid chamber in the inner member through restricted orifice means.

A New Type of Nonlinear Viscous Damper

Applied Mechanics and Materials, 2012
In order to satisfy the needs in engineering practice，a new type of nonlinear viscous damper with conical valves is developed. There is a through hole and two valves in the piston of the damper. When the damper work, the fluid flows throw the hole and the regulators, then the energy is consumed.

The damping algorithm and design of viscous damper

2019 IEEE 8th International Conference on Fluid Power and Mechatronics (FPM), 2019
The energy dissipation mechanism of hydraulic viscous damper was studied considering the shear thinning effect of dimethyl silicone oil. The analysis indicates that most of the energy loss occurs in the damping hole, which is mainly manifested as the damping loss along the path. The calculation formula of damping loss is simplified by assuming boundary

Viscous damper development and future trends

The Structural Design of Tall Buildings, 2001
AbstractViscous dampers can protect structures against wind excitation, blast and earthquakes. Viscous damper technology originated with military and aerospace applications. Approximately 10 years ago it was found that the same fluid viscous dampers that protect missiles against nuclear attack and guard submarines against near‐miss underwater ...

Mitigation of micro vibration by viscous dampers

Earthquake Engineering and Engineering Vibration, 2009
This study proposes a micro vibration mitigation system using viscous dampers to solve the problem of vibration in a high-tech building. Due to the operating frequency of the air conditioners and fundamental mode of the floors, a resonant phenomenon is occasionally experienced at the upper levels of the structure.
