摘　　要：电磁激振器是一种提供激振力的装置,具有工作频带宽、体积小、激振力自重比大等优点。文章简要介绍了其工作原理,在此基础上设计了一种新的内磁式电磁激振装置,并详细阐述了电磁激振器动态特性和电磁激振力的一般表述形式,对电磁激振装置的设计选用具有一定的指导意义。Electromagnetic vibrator is a device that supplies exciting force. It possesses the advantages of wide bandwidth, small volume, and high exciting force /weight ratio etc.. A new vibration device was designed based on working principle, which was introduced in this paper at first. Dynamic characteristics and common presentation of exciting force were presented in detail. The results presented here are useful for designing and choosing the device.

关 键 词：电磁 动态特性 激振力
