中文摘要:

电磁的团更潮湿(EMD ) ,控制系统减少结构的颤动的一个创新活跃控制系统,在传统的活跃质量上提供许多优点司机 / 阻尼(AMD ) 控制系统。在这篇论文,摇晃的几 EMD 控制策略和凳子规模的研究搁置二故事的模型结构的测试被描述。首先,相应于的二个结构的模型不受管束并且 Zeroed 盒子被开发,并且这些模型的参数通过正弦曲线被验证打扫测试为为进一步的研究建立一个精确数学模型提供一个基础。然后,为 EMD 系统的简化控制策略基于杆赋值控制算法被建议。而且,理想的杆地点通过一系列摇晃的桌子测试被导出并且验证。最后,三个基准地震地面运动和正弦曲线打扫波浪被强加到结构上调查为结构的颤动控制使用这类创新活跃控制系统的有效性和可行性。另外, EMD 系统的坚韧性被检验。测试结果证明 EMD 系统是为结构的颤动的控制的一个有效、柔韧的系统。

英文摘要:

The electromagnetic mass damper (EMD) control system, as an innovative active control system to reduce structural vibration, offers many advantages over traditional active mass driver/damper (AMD) control systems. In this paper, studies of several EMD control strategies and bench-scale shaking table tests of a two-story model structure are described. First, two structural models corresponding to uncontrolled and Zeroed cases are developed, and parameters of these models are validated through sinusoidal sweep tests to provide a basis for establishing an accurate mathematical model for further studies. Then, a simplified control strategy for the EMD system based on the pole assignment control algorithm is proposed. Moreover, ideal pole locations are derived and validated through a series of shaking table tests. Finally, three benchmark earthquake ground motions and sinusoidal sweep waves are imposed onto the structure to investigate the effectiveness and feasibility of using this type of innovative active control system for structural vibration control. In addition, the robustness of the EMD system is examined. The test results show that the EMD system is an effective and robust system for the control of structural vibrations.
