Internal viscous damper monitoring system and method
The Journal of the Acoustical Society of America, 2008A method for operating an internal combustion engine of a vehicle traveling on the road, the method comprising of damping engine vibration with a damper coupled to the engine, and when said damping is reduced, preventing engine speed from falling below a threshold value, at least under selected operating conditions, to reduce degradation of the engine ...

Improvement of Building Resilience by Viscous Dampers
2019In recent years, structural control strategies have been very important in earthquake and wind resistant designs in the world. In the classical period, structures were designed only for vertical loads. The modern period brought about dynamic calculation methods and applications.

The Extended Theory of the Viscous Vibration Damper
Journal of Applied Mechanics, 1955Abstract 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.

Seismic protection of bridges using viscous dampers
2012The proposed paper deals with the seismic protection of bridges by means of passive energy dissipation viscous devices installed between the continuous beam deck and the supporting piers. An analytical approach is used to study the problem and a simple design procedure, using the frequency response analysis, is provided to determine the optimal value ...

Nonlinear Damping: From Viscous to Hysteretic Dampers
2017This paper is dedicated to a brief discussion on the nonlinear damping. We present the particular results for linear and nonlinear viscous dampers, for fractional damper and for the hysteretic damper . As a main purpose we consider the mathematical model of damper with hysteretic properties on the basis of the Ishlinsky-Prandtl model.
