Inner mass impact damper for attenuating structure vibration

Dynamic behaviour of composite mass damper for control of wind-excited vibration

The aim of this paper is to study the effectiveness of the passive, active and semiactive versions of the composite tuned mass damper systems to reduce vibrations of building structures exposed to strong winds. The LQR method is used to determine the active and semi-active control forces. Several remarks concerning the effectiveness of considering dampers are formulated on the basis of extensiv...

Transverse Vibration Control for Cable Stayed Bridge Under Construction Using Active Mass Damper

Fuzzy Control of Seismic Structure with an Active Mass Damper

Fuzzy theory is highly promising for active structural control. The advantage of fuzzy controllers over classical controllers is the limited number of measured structural responses used to implement the control rules and its intrinsic robustness. In this paper, Fuzzy rules were generated firstly by learning from sample data obtained from the performance of the system under optimal control algor...

Vibration Control of MR Damper Landing Gear

In the field of Automation, Fuzzy Control Fuzzy control has significant merits which are utilized in intelligent controllers, especially for vibration control systems. This paper is concerned with the application aspects of the developed MR damper for landing gear system, to attenuate the sustained vibrations during the landing phase. Also a comparative study is made on the responses obtained f...

Harmonic analysis of a magnetorheological damper for vibration control

Semi-active control systems are becoming more popular because they offer both the reliability of passive systems and the versatility of active control systems without imposing heavy power demands. In particular, it has been found that magnetorheological (MR) fluids can be designed to be very effective vibration control actuators, which use MR fluids to produce controllable damping force. The ob...
