An Active Damper System for Hybrid Control of Bridges Under Earthquakes

9402535戈尔达内贾德需要桥梁和其他大型民用建筑的创新控制系统，以加强在地震、强风和其他人为和自然灾害情况下的安全。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。通过施加不同的激振力和频率，以及使用几种不同的电流变液和压电传感器，将仔细检查模糊控制器的自适应特性和控制器可能发生故障的条件。将通过地震模拟和真实桥梁的分析模型来检验所建议的阻尼器的实施。***

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. ***
