An Active Damper System for Hybrid Control of Bridges Under Earthquakes

9402535 Gordaninejad需要创新的桥梁和其他大型土木结构控制系统，以提高在地震、强风和其他人为和自然灾害下的安全性。在本项目中，将开发电流变（ER）流体阻尼器、压电陶瓷传感器和自适应模糊控制器来控制桥梁结构的响应。模糊控制器的自适应特性和控制器可能失效的条件将通过施加不同的激励力和频率，以及使用几种不同的电流变换器流体和压电陶瓷传感器来仔细检查。所提出的阻尼器的实施将通过真实桥梁的地震模拟和分析模型进行检验。＊＊＊

9402535 Gordaninejad Innovative control systems for bridges and other large-scale civil structures are needed for enhancing safety in the event of earthquakes, strong winds and other man-made and natural hazards. In this project, electro-rheological (ER) fluid dampers, piezoceramic sensors and a self-adaptive fuzzy logic controller will be developed to control the response of bridge structures. The self-adaptive nature of the fuzzy controller and condition under which the controller may fail will be carefully examined by applying different excitation forces and frequencies, and by using several different ER fluids and piezoceramic sensors. The implementation of the proposed dampers will be examined through earthquake simulations and analytical models of real bridges. ***
