Efficacy of Tuned Mass Dampers for Bridge Flutter Control
This paper examines efficacy of tuned mass dampers ~TMD! in controlling self-excited motion resulting from negative damping. New optimal TMD parameters are suggested which provide better performance than those suggested in the literature. The dependence of TMD performance on structural damping is highlighted. The equations of motion of a combined system comprised of multiple TMDs attached to a ...
متن کاملSemiactive Tuned Mass Dampers
Studies have already demonstrated the successful use of linear semiactive damping devices, such as variable orifice (VO) dampers, for semiactive TMD systems. More recently, nonlinear semiactive damping devices, such as magnetorheological (MR) dampers, have also been shown to be effective for semiactive control of TMDs. Though semiactive dampers differ widely, with responses ranging from linear ...
متن کاملTuned Mass Dampers in Passenger Cars
It is very well known that tuned mass dampers are engineered to minimise the vibrations in buildings in earthquake prone areas and in some cases machinery [1]. This paper evaluates the utility of Tuned Mass Dampers in passenger cars. For the same suspension system, addition of a tuned mass was found to reduce the transmissibility by a considerable amount. Addition of a tuned mass also helps in ...
متن کاملCOMPARISON OF RELIABILITY BASED AND DISPLACEMENT BASED OPTIMIZATION OF TUNED MASS DAMPERS REGARDING UNCERTAINTY
Some structural control systems have been devised to protect structures against earthquakes, which the tuned mass damper (TMD) being one of the earliest. The effect of a tuned mass damper depends on its properties, such as mass, damping coefficient, and stiffness. The parameters of tuned mass dampers need to be tuned based on the main system and applied load. In most of the papers, the paramete...
متن کاملTHE CAPABILITY OF OPTIMAL SINGLE AND MULTIPLE TUNED MASS DAMPERS UNDER MULTIPLE EARTHQUAKES
The main focus of this research has been to investigate the effectiveness of optimal single and multiple Tuned Mass Dampers (TMDs) under different ground motions as well as to develop a procedure for designing TMD and MTMDs to be effective under multiple records. To determine the parameters of TMD and MTMDs under multiple records various scenarios have been suggested and their efficiency has be...
