Orthotropic steel bridge deck vibration reduction method based on leakage-proof magnetorheological damper
The invention discloses an orthotropic steel bridge deck vibration reduction method based on a leakage-proof magnetorheological damper, and relates to the technical field of structural engineering and automatic control. For vibration reduction of an orthotropic steel bridge deck, the leakage-proof magnetorheological damper is installed below the orthotropic steel bridge deck, the characteristic that the damping force of the leakage-proof magnetorheological damper is adjustable is utilized, an intelligent control algorithm is combined, real-time variable additional damping force is provided for the orthotropic steel bridge deck, deformation of the orthotropic steel bridge deck is reduced, thus the stress concentration degree is reduced, and the vibration reduction effect is achieved.
本发明公开了基于防泄漏磁流变阻尼器的正交异性钢桥面板减振方法，涉及结构工程和自动控制技术领域。针对正交异性钢桥面板减振提出了通过在正交异性钢桥面板下安装防泄漏磁流变阻尼器，利用防泄漏磁流变阻尼器的阻尼力可调特性，结合智能控制算法，为正交异性钢桥面板提供实时可变的附加阻尼力，减小正交异性钢桥面板的变形，从而降低应力集中程度，达到减振效果。
