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

Semiactive Control System based on MR Damper for Suppressing Vibration of Stay Cable under Wind Load

This paper investigates the performance of the semiactive control system based on magnetorheological fluid (MR) dampers for suppressing excessive vibration of stay cable installed in cable-stayed bridges under wind load. The cable model is extracted from a 156.3 m long stay cable with high tension. The external wind load is generated from the widely used wind load spectrum such as the Kaimal sp...

Development of a Self-Powered Magnetorheological Damper System for Cable Vibration Control

A new self-powered magnetorheological (MR) damper control system was developed to mitigate cable vibration. The power source of the MR damper is directly harvested from vibration energy through a rotary permanent magnet direct current (DC) generator. The generator itself can also serve as an electromagnetic damper. The proposed smart passive system also incorporates a roller chain and sprocket,...

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...

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...
