| Abstract: | The permanent-magnet adjustable magnetorheological damper has the advantages of no power source and adjustable damping capacity. The article studies the mechanics performance of this permanent-magnet magnetorheological damper by the experiment and puts forward the stay cable damping scheme with the permanent-magnet adjustable magnetorheological damper in the view of the stay cable vibration of Liuyang River Bridge in Changsha. The field damping experiment and the practical application result make clearly th... |
