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。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.
