较大的地板振动幅度可能会造成工作中断并降低员工的工作效率，在更极端的情况下，可能会导致结构完全放弃其预期用途。本文探讨了在轻型楼板系统中实施主动控制以降低振动水平的问题。已经开发了一种速度反馈方案，其中电磁检测质量致动器用于在地板系统上施加控制力，从而减小地板运动的幅度。的发展，分析和实验验证讨论成功实施此控制应用程序。一个全尺寸的实验测试地板的设计，建造，并模拟分析这项研究。地板瞬态激励响应的分析和实验结果表明阻尼从约2.5%增加到40%。步行激励的实验结果表明，峰值速度振幅的12%的振幅记录为…
Large floor vibration amplitudes can produce disruption and reduced efficiency in employees, and in more extreme cases can result in complete abandonment of a structure for its intended use. The implementation of active control to reduce vibration levels in lightweight floor systems is explored in this paper. A velocity feedback scheme has been developed in which an electromagnetic proof-mass actuator is used to impart control forces on a floor system, thus, reducing the amplitudes of the floor motion. The development, analysis, and experimental verification are discussed for the successful implementation of this control application. A full-scale experimental test floor was designed, constructed, and modeled analytically for this study. Both analytical and experimental results for the floor response to transient excitation show an increase in damping from approximately 2.5% to 40%. Experimental results for walking excitation show a reduction of peak velocity amplitudes to 12% of amplitudes recorded for th...
