Semi-Active Pulse-Switching SSDC Vibration Suppression using Magnetostrictive Materials
One of the best vibration control methods using smart actuators are semi-active approaches which are as strong as active methods and need no external energy supply such as passive ones. Compared with piezoelectric-based, magnetostrictive-based control methods have higher coupling efficiency, higher Curie temperature, higher flexibility to be integrated with curved structures and no depolarizati...
متن کاملThe effect of semi-active controller in Sirri jacket seismic vibration control
The Sirri jacket offshore platform was designed and installed in Persian gulf of Iran in 1975 and has been in service since that time. The importance of offshore structure's stability and the failure of this kind of structure during an earthquake in different active zones revealed that earthquake loading has to be considered. In this paper, Magnetorheological (MR) fluid dampers have been propos...
متن کاملSweeping piezoelectric patch vibration absorbers
This paper presents a simulation study concerning the low-mid frequencies control of flexural vibration in a lightly damped thin plate, equipped with five time-varying shunted vibration absorbers. The panel is excited by a rain-on-the-roof broad frequency band stationary disturbance. The absorbers are composed of piezoelectric patches connected to time-varying RL shunt circuits. Continuous, swe...

متن کاملThe Study and Development of Energy Harvesting Vibration Absorbers
Vibrational energy harvesting seeks to convert ambient energy into electricity when battery replacement or line transmission is infeasible or impracticable. Electromechanical mass-spring harvesters are designed to exhibit a resonance frequency close to the principal vibrational frequency of the main or environmental system; excited near to resonance, the harvesters convert the kinetic or potent...
