摘要
控制结构体的振动是工程结构研究的热点。磁悬浮技术是一种集电磁学、电子技术、控制理论、信号处理的新兴智能技术。运用可控磁悬浮技术的工程结构减振控制方法,是指在地震动或风荷载作用下,利用磁浮力在受控结构与支承结构之间产生预定的间隙,使受控结构脱离支承结构,把振源与受控结构完全隔离,从而达到隔振的目的。文章评述了磁悬浮技术在航天航空、机械制造和磁浮列车等领域的研究和应用,提出了利用磁悬浮技术进行工程结构减振控制的设想以及需要进一步研究的问题。
Vibration control of structures is always concerned by researchers. Magnetic levitation is an emerging in- telligent technique, which integrates electromagnetism, electronic technique, control theory, and signal processing. Engineering vibration control method based on magnetic levitation is to separate buildings and its base by a certain clearance with the aid of magnetic levitation technique for eliminating or reducing the effect of terrestrial vibrations and wind loads on buildings. This paper is to provide a stated-of-the-art review of researches and applications of magnetic levitation technique in aviation and space, machinery vibration isolation, and magnetically levitated train. Finally, the ideas and problems of applying magnetic levitation to buildings are presented.
