【摘要】 基于压电元件的被动控制技术正得到越来越多的重视。该文针对一种新型的被动减振技术———基于压电元件的同步开关减振技术,进行了理论分析和实验研究。详细阐明了同步开关减振技术的原理,并以根部粘贴有压电陶瓷片的悬臂梁系统为例,对同步开关振动控制进行了实验研究,给出了被动减振的实验结果。更多还原

【Abstract】 At present,more and more attention is paid to the passive control based on piezoelectric ceramic.Recently,a new passive control technology appeared.In this paper,this new technology-synchronized switch damping (SSD) is discussed in detail.At last,a practical circuit of SSD is designed and implemented with an experimental simply supported cantilever beam.更多还原
